When using PlatformIO it is not enough to only include this library repo in the library dependencies. The library Adafruit_BusIO is also required and I think the README in this repository should mention it at the very least.

platformio.ini Example:

; Libraries
lib_deps =
     https://github.com/adafruit/Adafruit_BusIO
     https://github.com/adafruit/Adafruit_INA260

Having used the library manager in PLatformIO V1.41.1 to download the Adafruit INA260 Library (V 1.3.2), on compiling a fatal error is generated concerning a library dependency of Adafruit_I2CDevice.h. This is including the provided examples, outside of my own project.

*** [.pio\build\nodemcu-32s\src\main.cpp.o] Error 1
In file included from C:\Users\Dave.platformio\lib\Adafruit INA260 Library_ID6239\Adafruit_INA260.cpp:37:0:

Already having I2C devices operating in my project (ESP32s, framework Arduino), and not being able to find the specified library, is there a way around this issue?

When ever i want to measure voltage it only give me 0.00125 volt or less. looks like noise tbh.

i tested a battery i had lying around that was 3.4V. i tested that with a multimeter.

When i attached the ends to the V+ and V- terminals and did the test with the ina260 it showed the very low voltage.
when i tested it with my multimeter it also showed a very little voltage.

now i checked the code of the ina and to my surprise it always measures current and voltage at the same time! which is so weird because a current measure will just short circuit the battery. this would explain the low voltage.

but how do i set the ina260 into a mode so that it only measures voltage?

I've see that reading of alarm limit level, of cause set too, will be multipled (divided in setAlarmLimit) with 1.25. But LSB of power isn't 1.25mW, it is 10 mW.

There are a couple pointers that are dynamically allocated in the begin function that do not seem to ever be explicitly freed.

Although this may not be a problem for most projects because the object will probably stay around for the lifetime of the entire code execution, creating and destroying multiple Adafruit_INA260 objects could cause a memory leak.

Adding a simple destructor that frees these pointers if they have been allocated would address this issue.

Thanks,

Line 30 and 31 in Adafruit_INA260.h is:
#define INA260_REG_MASK_ENABLE \
0x06 ///< Interrupt/Alert setting and checking register

Don't know if this will cause any issues with compilation or code functioning.

Should be?
#define INA260_REG_MASK_ENABLE 0x06 ///< Interrupt/Alert setting and checking register

^^

I have read the documentation and comments and cannot find detail of how the set the Alert trip point. Can someone please send me in the right direction? Will need to set current trip.

Dear adafruit team,

1.3.0 from (platformio) PIO’s eyes is commit 7f5760f, aka 3 commits behind master.

Therefore please increase library version number to 1.3.1 to solve this issue.
