Platform.io still shows v0.1.5, seems it need a kick to pull in the current v0.1.6

Hey! I'm porting my ttgo t-beam's code to run on the newer model with AXP2101. For AXP192 I've got these lines of code reading the current consumption:

status.batt_milliamp = pmu->getBatteryChargeCurrent();
status.batt_milliamp = -pmu->getBattDischargeCurrent();
status.power_draw_milliamp = pmu->getVbusCurrent();

Is there an equivalent for AXP2101?

Thanks.

Espressif defines a PMU variable declared as extern for some of their SOCs (in my case it was the ESP32H2):
https://github.com/espressif/esp-idf/blob/1cb4f3468d64c9e8bde196b15df37cbcd4b31395/components/soc/esp32h2/include/soc/pmu_struct.h#L761
This code is precompiled into the esp32-arduino-lib library installed by Arduino. If you run the example programs on these SOCs, everything will get messed up due to the global PMU variable.

I encountered this problem when debugging the sleep function of ESP32-H2. It took me some time to troubleshoot this issue because the compiler doesn't directly prompt the error.
The sleep-related functions of ESP32-H2 will reference the PMU variable, which will cause the sleep function to not run properly and cause core panic.
https://github.com/espressif/esp-idf/blob/1cb4f3468d64c9e8bde196b15df37cbcd4b31395/components/esp_hw_support/sleep_wake_stub.c#L71-L74

This problem can be reproduced by running AXP2101_Sleep_Example.ino on ESP32-H2. Switch 'Core Debug Level' to 'Verbose' and it should show something like

Is it true that the first time it starts, the DCDC1 voltage will be 3.3 Vdc according to section 7.6 of the datasheet I attached? How will the starting order of the voltages be configured? I don't see instructions in the documentation.
Please help me!

Would it be possible to release the new changes and pio pkg publish them ?
Thanks!

AXP192_showstatus(): [src/power.cpp] Battery charging, 0.00V @ 752mAh

code:

if (pmu.isBatteryConnect())
    if (pmu.isCharging())
      ESP_LOGI(TAG, "Battery charging, %.2fV @ %.0fmAh",
               pmu.getBattVoltage() / 1000, pmu.getBatteryChargeCurrent());

Hello, from the datasheet I read that the AXP2101 pin for EX/PWRON can be configured as "enable pin" so that we do not need the PWRKEY to be pressed every time.

from the library it is not clear to me how to setup the PMU so that it will simply turn on/off using the pin as an ENABLE signal.

could you please help ?

thanks

Hello Dear,

Thanks alot for your work.
I think the structure should start with 1 and not with 0 according to the datasheet.
000 is 'reserved'
Kindly check if i am right or wrong.
This the following changes the charger outputs a proper voltage.
typedef enum __xpowers_axp2101_chg_vol {
XPOWERS_AXP2101_CHG_VOL_4V = 1,
XPOWERS_AXP2101_CHG_VOL_4V1,
XPOWERS_AXP2101_CHG_VOL_4V2,
XPOWERS_AXP2101_CHG_VOL_4V35,
XPOWERS_AXP2101_CHG_VOL_4V4,
XPOWERS_AXP2101_CHG_VOL_MAX
} xpowers_axp2101_chg_vol_t;

Is there any way to get current system uses, my board have SY6970 chip.
Thank you!

Hi,

I'm trying to init/begin the chip AXP2101 of the new T-Beam V1.2

#define I2C_SDA 21
#define I2C_SCL 22
bool result = PMU.begin(Wire, AXP2101_SLAVE_ADDRESS, I2C_SDA, I2C_SCL);

results always returns 1 , which I asume is "not" begin successful, right?

Hi,

First of all impressive work. I see there is I2C address for SGM41511 does this work fine with that IC?

Thanks

Thanks!

Hi,

I've been trying to use the library in my project from PlatformIO (v0.1.7) but after having it included in my espidf pure C code, the compiler complains about hpp and tpp files (because they are actually not C friendly and cannot be compiled and included in a C project: see https://stackoverflow.com/questions/152555/h-or-hpp-for-your-class-definitions).

Can you please make it so it would be usable? Or is there an alternative to manage the PMU (I have T-7080G-S3) using other libs?

Hello, firstly thank you for creating and managing this library. It has been very helpful to track these parameters of the microcontrollers.

I have 2 T-Beams, one with the AXP192 and one with AXP 2101. My aim is to retrieve if the T-Beam is charging, temperature, battery voltage and percentage and forward it to TTN. For the AXP192, I can see all these parameters but for AXP2101, the example does not show how to retrieve temperature data.

However, when I add the statement PMU.getBattVoltage() and print it out and send it to ttn, it produces a faulty value. For example. it returns temperature as 58.2 degrees when it should be in the 30s range. Is this function not configured for the AXP2101?

Thank you.

Hello, i'm trying to compile some examples and when i open the "AXP2101_Example" right at the start the file i see:

// Defined using AXP2102
#define XPOWERS_CHIP_AXP2102

And if i try to use:

#define XPOWERS_CHIP_AXP2101

it doesn't exist, so do AXP2101 and AXP2102 use the same protocol and can be used interchangeably? or i'm just a dummy?

Dear lewisxhe,
when I scan i2c address, I received 0x34.
but when I use example AXP2101_Voltage_Example, I received "PMU is not online"
I don't know why, i2c bus is ok, 2 resistors pullup is ok, but my device can't connect to AXP2101!

The charging current is only about 3-5mA, so the charging time exceeds 12H (set by reg67H[5:4]), and thus also interrupts the charging process. I can't fix this problem, please help me!

Is there an equivalent library for a battery powered ESP32-S3 to the AXP202 library for the TTGO T-Watch.
Currant usage could be measured without a device, such as an INA219 module.
The getBattChargeCurrent() and getBattDischargeCurrent() function are very useful.

Hello Dear,

May be this issue is not related to the library.
But i have no any other support sources.

The new boards arrived. All 50 are having strange behavier.
It is eather electrical connection issue or AXP2101 are faulty.

I am receiving this IRQ's in a raw and after that MPU shutdown:
isVbusRemove
isBatInsert
isBatRemove
isPekeyShortPress
isPekeyLongPress

This issue can happen during charging or during normal operations.
This issue can happen 1 hour after start or even 40 hours after start.
And i can not find any links to anything. It is just random shutdowns...

I am using
DCDC1 as ESP32 + Radio module power supply (max 0.6A total)
DCDC3 as GPS power supply (max 0.3A)
ALDO1 as gyro power supply (little load)
ALDO2 as spare power supply.

Kindly help with your expirience.
