It seems that mraa and upm libraries and not maintained anymore. So you cannot use mraa and upm related Grove modules. FIX THIS BLOODY ISSUE AND DO NOT CLOSE IT AGAIN UNTIL IT IS FIXED.

The analog to digital converter (ADC) of the [https://wiki.seeedstudio.com/Grove_Base_Hat_for_Raspberry_Pi/](Grove Base Hat for Raspberry Pi) is no longer working after commit a4a5c9b.

To get it working, the i2c address 0x04 must be explicitly passed to the ADC class constructor:

from grove.adc import ADC
adc = ADC(address = 0x04)

My understanding is that Seeed is prioritizing a new default micro-controller for the Base Hat (change from STM32 to MM32). However, it is important to clearly inform those who have the STM32 Base Hat of the changes and how to get it working.

I suggest adding a note to the adc.py module and a note on the Base Hat's Wiki page.

Hi,
I am working on interfacing grove ultra sonic sensor v2.0 with my Jetson NX board. I dont have a base hat/shielf/I2C adapter. I want to interface the sensor directly with Jetson board.

I started with looking into : https://wiki.seeedstudio.com/Grove-Ultrasonic_Ranger/ where they have mentioned "If we don't have Grove Base Shield, We also can directly connect Grove_Ultrasonic_Ranger to Seeeduino as below." But this example C library will not work since it uses arduino library.h.

Then I started to work with code in this git: https://github.com/Seeed-Studio/grove.py/blob/master/grove/grove_ultrasonic_ranger.py
Like I mentioned I dont have base shield so I replaced (pin number) with my GPIO pin and got the below error.

Check whether I2C enabled and Grove Base Hat RPi or Grove Base Hat RPi Zero inserted

So i had to remove the lines 98 to 100 and directly configure my pin number and try. It is just printing "Detecting distance.." and nothing else.

It would be really helpful to get some inputs on this.

Regards
Niranjan

In the GPS module code, the only source that is detected is GP, the US GPS constellation. The Air530 sensor supports other constellations, but this library is unable to detect them.

The logic in the read function should ignore the 2 characters for the sender field at the start of the NMEA message to support other constellations.

I installed the package as it is described in the documentation but I can't call GPIO of grove.gpio like from grove.gpio import GPIO because it throws an error that No module named grove.gpio etc. But when I copy my python file into the root directory of grove.py and run it, everything seems ok and the code works. What is the problem with that? Shouldn't I be able to run my codes which call grove classes/modules from any location on a Pi?

I tried to follow grove water sensor example shown in https://github.com/Seeed-Studio/grove.py/blob/master/grove/grove_water_sensor.py
The below condition is opposite in my case:

if sensor.value > 800:
            print("{}, Detected Water.".format(value))
        else:
            print("{}, Dry.".format(value))

It prints >800 Detected water when sensor is not in water and prints <800 Dry when sensor is in water..

Is that expected ?

Hi, I'm getting some permissions errors I can't seem to resolve on my own when running curl -sL https://github.com/Seeed-Studio/grove.py/raw/master/install.sh | sudo bash -s –
I've tried running the curl command as root, and setting sudo's -H flag as the error message suggests, but still got the following errors. Was wondering if you had suggestions for getting around what appears to be user conflicts between user root and my user?

I could not find any information about the Infrared Temperature Sensor (MLX90615).

Did anyone made this running on a RPI?

using GROVE BASE HAT RPI with Grove - RGB Led ring (16-WS2813 Mini)
On Rpi 3B Buster version
The Led are on PWM slot .
i can't get the leds switch on
and no error message is given

code :
from grove.i2c import Bus
from rpi_ws281x import PixelStrip
from time import time, sleep
from grove.gpio import GPIO
from RPi import GPIO as io

def light_led(led, pix, r, g, b):
for pixel in range(pix):
led.setPixelColorRGB(pixel, r, g, b)

print("led mode {} {} {}".format(str(r),str(g),str(b)))
led.show()

led20 = PixelStrip(16, 12) # Grove RGB led connected to grove PWM
led20.begin()

light_led(led20, 16, 55, 0,0)
sleep(5)
light_led(led20, 16, 0, 55, 0)
sleep(5)
led20._cleanup()

in i2c.py the line #51

Bus.instance = smbus.SMBus(bus)

causes problems when trying to open two distinct i2c busses from the same app. in our case both calls would open a device on the same i2c bus.

changing to

self.instance = smbus.SMBus(bus)

fixed the problem.

using respberry py at the paj7620 sensor on i2c bus 1 & 3

Can the Raspberry Pi Pico utilize grove.py ?

If so, how does one install it ?

If not, is there a different repository to look at ?

Is there a possibility to have a code example for programming the grove led bar?

Hello,

I've been playing around with an OKdo Air Quality kit and I seem to have fallen at an early hurdle.

The installation of grove.py on to a Pi using the command below seems to go well until the very end where I am told that the installation failed.

Any thoughts on how to solve this would be awesome.

Hi,

I there also support for grove_6_axis_accel_gyro_bmi088 for Jetson NX?

Thanks !

Hello,

When I use "curl -sL https://github.com/Seeed-Studio/grove.py/raw/master/install.sh | sudo bash -s -" on Jetson nano, the output informs me as:

Err:18 https://seeed-studio.github.io/pi_repo unknown Release
404 Not Found [IP: 185.199.109.153 443]

Any suggestion?

Thanks!

I want to use Temperature & Humidity Sensor(DHT11).

I installed grove.py following the steps.
But [grove_temperature_humidity_sensor] Command is not found.
Also, I can't find the source code(grove_temperature_humidity_sensor.py).

[grove_temperature_humidity_bme680] Command and [grove_temperature_humidity_sht31] Command can be confirmed.

Please let us know if you know why it doesn't work.
Thank you very much.

This issue was reported by @nikolozka in Issue #12.

The issue is still in the code and I would like to submit a PR for it, however, I'm trying to understand the reasoning behind this.

class Bus:
    instance = None
    MRAA_I2C = 0

    def __init__(self, bus=None):
       ... skipping code ...

       if not Bus.instance:
            Bus.instance = smbus.SMBus(bus)

      ... rest of code ...

Why is instance being used as a class attribute? It effectively makes the Bus class a singleton class.
Are there any advantages to doing this that I'm missing?

To reproduce this problem:

• Connect a Base Hat to the reTerminal.
• Use an analog sensor such as the Grove Soil Humidity sensor with the ADC of the Base Hat.
• Create a new I2C bus 4 for the reTerminal (using this example).
• Connect an I2C sensor such as the AHT20 temperature & humidity sensor to the base hat.
• Try to read from both sensors.

File "/usr/local/lib/python3.7/dist-packages/grove/grove_temperature_humidity_aht20.py", line 44, in read
    self.bus.write_i2c_block_data(self.address, 0x00, [0xac, 0x33, 0x00])
File "/usr/local/lib/python3.7/dist-packages/smbus2/smbus2.py", line 643, in write_i2c_block_data
    ioctl(self.fd, I2C_SMBUS, msg)
OSError: [Errno 6] No such device or address

Any idea on if or when this will be available? Or does anyone know of any alternative libraries I can use to connect the Jetson Nano to an LED strip (not just aWS2813 - I'm also looking at using a WS2812 or WS2812B)

     Grove.py installation FAILED, FAILED, FAILED      
-------------------------------------------------------

This looks like the Python2 packages are not compatible with bullseye, which makes sense as Python2 has been deprecated. It would be nice if the script was update to only install Python3 libraries to avoid these errors.

If I import this:

from grove.factory import Factory 

and run python3 main.py, I get:

Illegal instruction

Any idea why?

I'm a pretty new user of Grove modules. I have successfully run 16x2 LCD and ultrasonic ranger with that Python library but I can't run IMU9DOFICM20600 (gyro/accelerometer/compass) with it.

What I try:

from grove.grove_imu_9dof_icm20600_ak09918 import GroveIMU9DOFICM20600

imu = GroveIMU9DOFICM20600()

and just instantly I get an error message being logged: Failed to open i2c bus /, error = -1. It's not an exception, I can still go on and run methods like imu.get_accel() or imu.get_gyro() but they keep returning all zeros. That module have no documentation in the library so I don't have an idea if I do something wrong. Did anyone use that module and can confirm it works?

Device info:
Raspberry Pi 2B
Raspbian 10 "Buster"
Python 3.7.3
I use Grove Base Hat for Raspberry Pi.
IMU 9DOF v.2.2 is connected to the first I2C port on the hat.
I have the newest version of the library installed from source.
I have other devices connected to the hat (ultrasonic ranger and LCD) but tried to remove them and it didn't help.
I've run i2cdetect and it seems like 68 address is detected.

Hello. I want to use GrovePi on my Raspberry Pi 4 on top of IoT Edge runtime (docker engine).
I prepared python module, but have problems with installing all dependencies in dockerfile.
I am using: arm32v7/python:3.7-buster as base image. Image using Debian GNU/Linux 10 (buster) as OS.
Using instructions of both auto and manual install of dependencies, I end up with error:

The following packages have unmet dependencies:
 python3-mraa : Depends: libpython3.5 (>= 3.5.0~b1) but it is not installable
E: Unable to correct problems, you have held broken packages.

The same instructions work well directly on Raspberry Pi 4. (which is Raspbian GNU/Linux 10 (buster))

I know that this is due to some python libraries missing - but both distributions have 3.7.5. What is done extra in Raspbian distribution that this instructions works, and on pure buster, not?

How to fix that?
Thanks in advance for help :)

I think this happens because libmraa1 cannot be located.

Installing libmraa from here with the following commands:

sudo add-apt-repository ppa:mraa/mraa
sudo apt-get update
sudo apt-get install libmraa2 libmraa-dev libmraa-java python-mraa python3-mraa node-mraa mraa-tools

After that, I executed the curl command again and got a little further but the installation of grove.py stilll fails because of libbma456:

I couldn't find out how to install the missing dependency libbma456. Any ideas how I can fix this? Thank you!

I want to use Grove Base Hat for Raspberry Pi 3B running Ubuntu 18.04 LTS.

I tried
curl -sL https://github.com/Seeed-Studio/grove.py/raw/master/install.sh | sudo bash -s -
But it never succeeds with the below error messages,
main line 30: lua command not found
main line 82: dtparam command not found
E: Unable to locate package libmraal
dpkg-query: package 'libmraa1' is not installed and no information is available

I have executed "sudo add-apt universe" so that i see "universe" in /etc/apt/source.line

My goal is to complete installing grove.py so that user application has path to Grove hardware

I have two different raspberry Pi 4 b and each has the same issue.

'No modules name upm'

I followed the instructions on #46 but it didn't work.

I also followed all the instructions on the wiki as well.

I have I2C enabled.
Python 3.9.2
OS: Linux Debian GNU Linux 11

It was the 64-bit image provided by Raspberry Pi folks.

Please advise.

Thank you

The code I'm running is from: https://github.com/Seeed-Studio/Seeed_Python_SI114X/blob/master/examples/BasicRead.py
but the error message indicates that it's within this library? (please correct me if I'm wrong)

• I found some sources claiming that the "OSError: Please check if the I2C device insert in I2C of Base Hat" is due to incorrect wiring but I don't see how this would be the case when using the Pi hat..
• I've checked with "i2cdetect -y 1" to make sure the device is recognised (it is)
• The above error ("OSError: [Errno 121] Remote I/O error") goes away when I type in the I2C device address manually (in my case 0x53), but the bottom error ("OSError: Please check if the I2C device insert in I2C of Base Hat") remains..
• I'm using this module from grove: https://wiki.seeedstudio.com/Grove-Sunlight_Sensor/
• I've tried clean-installing from scratch and only downloading the required libs for the hat+sensor
• I've also tried installing from source (this repo) instead of fetching directly from pip
• I've tried using a different Pi (same specs) just to be sure it's not an issue with my pi

Unfortunately I don't have any other I2C devices I can try.

I'm running raspbian 11 (bullseye) on a raspberry pi 4

Hey, why is this code not on the master branch?
https://github.com/Seeed-Studio/grove.py/blob/8205879e6e96be4f9c9159b01c347ce1be1be2e5/grove/grove_temperature_humidity_sensor.py

The sensor documentation refers to non-existing files.
http://wiki.seeedstudio.com/Grove-TemperatureAndHumidity_Sensor/

The DHT11 sensor cannot be tested without this example.

https://github.com/Seeed-Studio/grove.py/blob/master/grove/grove_gesture_sensor.py

		if data0 != 0x20  :#or data1 <> 0x76:
			print("Error with sensor")
		

Only one byte is checked - second check is commted out. Why?

if data == self.GES_FORWARD_FLAG:
				return 1
				time.sleep(self.GES_QUIT_TIME) 

Multiple dead code statments after return?

 } else if (data == GES_FORWARD_FLAG) {
                    Serial.println("Forward");
                    delay(GES_QUIT_TIME);
}

Problem

The smbus instantiation logic in i2c.py selects the wrong i2c bus number for CM4 Pi.

This presents itself in the form of an uncaught IOError that crashes a python script when any of the adc methods are called, for eg:

>>> from grove.adc import ADC
>>> adc = ADC() 
>>> print(adc.read_voltage(0))
Check whether I2C enabled and   Grove Base Hat RPi  or  Grove Base Hat RPi Zero  inserted

I have written a workaround (see Bug Fix) but I don't understand the i2c logic well enough to know if this is the appropriate resolution in general.

Explanation

When the ADC class is instantiated, the bus number is chosen based on the value of GPIO.RPI_REVISION. See https://github.com/Seeed-Studio/grove.py/blob/master/grove/i2c.py#L39-L49.

I don't understand the motivation behind this choice, but I can see it causes the wrong outcome for CM4 Pis (such as the reTerminal).

The CM4 has RPi.GPIO.RPI_REVISION=0. https://raspi.tv/2014/rpi-gpio-quick-reference-updated-for-raspberry-pi-b.

The above logic results in bus=0 for the smbus used by the adc class. However, the bus should be 1, as can be seen by running i2cdetect:

pi12@pi12:~/ $ i2cdetect -y 0
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

Environment

• Hardware: reTerminal with CM4
• OS: Raspberry Pi OS, Debian 12 Bookworm 64bit
• ADC: Grove Base Hat

Example

Assume there is an analog device connected at A0, that the i2c interface is enabled, and that there are no wiring issues (as can be seen by the successful "Bug Fix" result).

Bug

>>> from grove.adc import ADC
>>> adc = ADC(0x04) # 0x04 for STM base hat, see https://github.com/Seeed-Studio/grove.py/issues/64 
>>> print(adc.read_voltage(0))
Check whether I2C enabled and   Grove Base Hat RPi  or  Grove Base Hat RPi Zero  inserted

Bug Fix

It is possible to extend the definition of the ADC class such that the bus number can be chosen at instantiation.

>>> import grove.i2c
>>> from grove.adc import ADC
>>> class customADC(ADC):
...    def __init__(self, address=0x04, bus=1)
...        self.address=address
...        self.bus=grove.i2c.Bus(bus)
...
>>> adc = customADC() 
>>> print(adc.read_voltage(0))
1628

Since we can make bus an optional parameter, this extension could be pulled upstream without breaking the interface, however, this would replace the existing bus determination logic.

Is that better? In my case, yes, since the bus determination logic does not work for my device. But, I'm not sure in general what makes the most sense, I don't understand how i2c bus numbers are determined for different devices.

Related issues

Not 100% certain, but this may be related to the following issues:

#70
#68
#61
#46

But both the https://github.com/Seeed-Studio/grove.py/blob/master/setup.py script as well as various documentation (e.g. https://wiki.seeedstudio.com/Grove_Base_Hat_for_Raspberry_Pi/#usage) prominently mention grove_pwm_buzzer.

I cannot find grove/grove_pwm_buzzer.py it in the current master branch. Only a pull request from some time back. #55
Am I doing something wrong or has the file been deleted for some reason?

Hi!
Not really an issue, but i cannot find any related script to the two digits display (https://wiki.seeedstudio.com/Grove-0.54_inch_Red_Dual_Alphanumeric_Display/). Any material you can share?

Cheers
