Receive command UART polling mode using LL library

Hi everyone!I've been trying to implement UART reception using LL library in polling mode. The code below is what handles the reception: uint8_t LL_USART_Receive_Byte(USART_TypeDef *USARTx) { // Wait for Read Data Register is not empty while (!LL_U...

Need more understanding about the Timer enabling fn I am changing CNT register of the Timer in order to get a changed time period on the go (for down counting mode), but doing so correctly is getting delayed by one period.

So I am using STM32H725 on which I have Timer 2 (general purpose timer) which is in down counting, one pulse mode with an interrupt which is triggered at underflow. Once the interrupt is fired, the TIMx_CNT register value is changed and then __HAL_TI...

Avoiding STM32 for new product designs?

Is it reasonable to consider using an STM32 for new product designs. Can't find any official statements of if and when any microcontroller will be available through official channels/distributors.

Encoder Z pulse Problem?

Hello Everyone!Wanted to ask because I have a problem with getting the z pulse, or index channel to work on my encoder. I am using an encoder on a motor, and a nucleo board, and programming everything on stm32cubeide.What is the correct way of doing ...

Can a Timer Trigger an Input Capture on another Timer in Encoder Mode?

On an STM32F746 I'm using TIM3 in encoder mode to count pulses from a motor's quadrature encoder. I'm using TIM2 to generate interrupts every 10 msec were I read the TIM3 CNT register to calculate the motor's RPM. There's some jitter here because of ...

We would like to be able to use the STM32F769NIH6 processor in our devices before 2026, but we cannot obtain it. I would appreciate it if you could let us know how and where to get it.

Dear Madam/Sir,As Tende, we produce medical devices for neonatal intensive care. We have been looking for a product that you can see below for a very long time, but due to the chip crisis, we are getting very high prices. Some items are not even offe...

HAL_FLASH_Program crashing my MCPU - but not in debug mode

I'm not completely sure where to start. But, I have 20k of data and I want to write to to flash.I'm using this function to do it (Start address is Bank2 of this processor 0x08080000)page size is 256 bytes, for this MCPU. (StM32L471)void Save_to_Flas...
