I am trying to take the spi class into use however I am always get the error: OSError: [Errno 22] EINVAL . I validated the Zephyr part of this, but everything seems to be well there.I also tried using another board using the zephyr port however there too I am getting same error. In the commit messag...

I am trying to get GPGGA data from the GPS on my board running the zephyr port of micropython. I am skeptical about the uart.readline() method of this port as it is not able to read the gps data.I also tried going deeper on the hardware level using a logic analyzer and everything seems to work well ...

I am using the Accel 10 click housing the LIS2DW12TR accelerometer and I want to run it using a MicroPython program.The code is as follows:https://github.com/Yadnik1/Accel10I2C/blob/main/ADXL345.py. The code prints out 0s abruptly and I am skeptical there I am making some mistake in the init functio...

Thank you scruss, Even after making all the changes like this: buf0 = b'\x55\x00\x01\xFE' buf1 = b'\x55\x01\x01\xFD' buf5= b'\x55\x05\xFA' buf10=b'\x55\x0A\x26\x00\xCF' buf17=b'\x55\x11\x01\xED' buf19 =b'\x55\x13\x01\xEB' buf25 = b'\x55\x19\x88\x88\x88\x88\x88\x88b\x84\x21\x08\x42b\x10\x80\x80\x80\x...

I think this what you were saying:

utime.sleep_ms(1)
uart.write(bytes(buf25))
utime.sleep_ms(1)
uart.write(bytes(buf10))
utime.sleep_ms(1)

However this also is returning only 0's, any other suggestions you have.
Thank you!!

Sorry scruss,
I will only post the part of code that does not work now onwards.

I tried using bytes(buf10),however that gives me an error saying SyntaxError: can't assign to expression . My code currently looks like this:https://github.com/Yadnik1/Ultrasonic-Click/blob/main/ultrasonic%20uart.py . Can you please have a look and please tell me any alternative of assigning the hex...

Thanks mhelm,
I would love to.Although it is not so generic, but is there a place I can take references from or any document I can follow.
Do I just have to make changes to the machine_uart.c file?

I did incorporate the changes in my code from the code : https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/910128/pga460-q1-pga460-q1-and-arduino However I am yet getting the same error i.e. my program returns only 0's Can you please have a look at my code:https://github.com/Yadnik1/U...

Thank you Robert,
The output I get is as follows:
