UART not working
I have an STM32WB55CGU6 on a custom board with a 32MHz HSE. I'm using low power uart1 with PA2 & PA3 pins. My settings for it are: - baud rate 9600- word length 8 bits- 1 stop bit- parity noneIt won't transmit. Cube doesn't receive it, any terminal ...
ST-LINK/V2 LPUART Connection
I tried to set up a UART connection from my custom board to my PC but encountered some problems and after a bit of probing, it seems that UART TX and UART RX are connected to GND. Do I need to enable UART somewhere for the ST-LINK ? Also why do some ...
SPI slave mode send data after transaction complete
I'm trying to send a fixed length packet in SPI slave mode from the STM32 via DMA. The SPI master may send/recv longer than that fixed length packet. It would be nice if the STM32 just sends 0 one the transactions is complete, but it seems to want to...
Trying to locate the ADC SAR sampling estimation tool

Resolved! FD_CAN How to reset error counter
In the FD_CAN register, there is a CEL[7:0]:, REC[6:0]: and TEC[7:0]:,The CEL register is not being reset on read and goes into the Bus-Off mode.Do I need to also reset the REC and TEC register?I am currently using the HAL_GetErrorCounter() function ...
Resolved! STM32G030 Oversampling Trigger Rate
I am a bit confused by the documentation on oversampling and the required trigger rate. I'd like to do 2 conversions a second on 5 channels using 256x oversampling. I have the ADC in continuous mode. I am triggering off TIM3 update. It's not clear...

Resolved! SysTick and FREE Rtos
Hi to everybody.I'm using H5 and FREE RTOS. I'm porting a project from M3 , than M4 now to H5. I used LL for all the periferals, but moving to HAL isn't a probelm (... but I prefer LL!).On M3 and M4 I used a timers to "serve" the RTOS scheduler, the...
