Good day I am sending a CAN message from a STM32F042. The first two bytes are the value read from an ADC split into 2 bytes. Then just for testing I set 4 bytes to "F042" which is then a fixed value that i know its sending what I ask. The problem I h...

I am not 100% sure what solved this, butni made the variable that i am putting into the TxData a pointer, it came out wrong for obvious reasons but for the first time i had a value from a variable that was the same in TxData and is was on the logic a...
