Sorry ST guys but the UART HAL and LL_HAL ist a total fail!I developing over 15 years all kind of serial communication with linux and different microcontrollers. Now I regret my desistion to use the STM32WB MCU. I'm trying over two weeks the get a st...

Hi there, I use the Nucleo-WB55 Board and I want to set some GPIO PINs in a high speed.I use Low Level code to get fastest response.GPIO_Init: GPIO_InitStruct.Pin = PID_D0_Pin|PID_D1_Pin; GPIO_InitStruct.Mode = LL_GPIO_MODE_OUTPUT; GPIO_InitStruct.Sp...

Hello, the project is now on hold because of some other priorities. I will be back if there is some time left... Thanks for your interest.

Thanks Piranha for your clear words and it confirms my assumption. I will check out the USART example you posted. The documentation looks promising to get a save an good solution...

Welcome to the 21 century, but polling was maybe ok in the 80ies. Polling it no rocket science thats right, but if you want to use a high end MCU/CPU thats the totaly wrong way....Why put ST this effort into examples and libraries which are not worki...

I started from zero with a new STM32CubeMX and STM32CubeIDE project including the latest HAL librarys. I use the Nucleo dev board and create a UART setup with interrupts, thats all.static void MX_USART1_UART_Init(void) { huart1.Instance = USART1; ...

Thank's this helps a lot. Both PIN's are set at the same time. 

STM32 UART HAL and LL failed

STM32wb55, why is GPIO so slow ? How can it speed up?
