Hello. I have problems with communication with TMC2209 through UART. It doesn't respond at all. I think that I've fried a receiver in UART1. Is that even possible? My board is Nucleo-F303k8. Please help me. Here's the code:/* USER CODE BEGIN Header *...

Hello. I have few questions on UART half-duplex single-wire peripheral. I'm using stm32f303k8.In RM it states that TX and RX are internaly connected and TX is low (or whatever "released" can mean) when it's not transmitting. This means that when no t...

Hello. I'm trying to obtain CRC value from CRC peripheral. It's supposed to give me 8 bit number. Instead it gives me 32 bit number. What am I doing wrong? Below is the code and program outputs. /* USER CODE BEGIN Header */ /** ********************...

No, I manually flipped 0xA0 to 0x05. Now I have to send it in MSB first order. 0xA0 in LSB order is 0x05.But it doesn't make sense why in CubeMX setting "MSB first" to Enable doesn't work while Disable works. This is sending 0x05 in LSB order and it ...

Praise Jesus! I prayed to Lord and He helped me!But still, it's weird. It started to work after I switched the "MSB first" option in CubeMX to Disable. I swear that before it worked with "MSB first" in Enable.But it doesn't make sense now honestly. T...
