circularbuffer / as5047p Goto Github PK

Hello CircularBuffer,

I am trying to use your library for the AS5047P and I am running into a bit of a problem. I get the error, "Error 3: Parity bit error occurred in Rx frame".

I am trying to use this with an STM32G431RB Nucleo-64 dev board and STM32CubeIDE 1.6.1. I have the sensor connected to SPI1 and I have the VCP setup to debug as in your example. I have walked through your instructions of setting up the 5 functions and also configuring the SPI. In my main.c I then call AS5047P_Init(&encInstanceA, 0);, AS5047P_SetFactorySettings(&encInstanceA); and AS5047P_SetZeroPosition(&encInstanceA); to set the sensor up. My logic analyzer shows that I am both transmitting data from the MCU and receiving responses from the sensor. But as soon as I call encPositionA = AS5047P_ReadPosition(&encInstanceA, AS5047P_OPT_ENABLED); I get Error 3 and the result of encPositionA is -1. Everything complies and there are no build errors.

Would you have an idea of what I am doing wrong? I feel like this is a simple fix, but I just can't see it. Any hints of help would be appreciated.

Sincerely,

Dylan
