While trying to get a bare metal environment up and running on the STM32G431 i seem to have found a way to brick both a nucleo-64 with an STM32G431RBT6 and a nucleo-32 with an STM32G431KBT6.The first one , i switched on the HSE, waited for it to be r...
Hi, I've been facing some issue using HAL_UART_TRANSMIT. The thing is that I want to send a message when I press a button. My idea is to catch the interrupt of the button and setting a flag, then in main sending the message detecting the flag.The pro...
Hi guys,I am using the STM32H750 and try to reprogram the internal 128KB flash.Please check my code as below :During the programming i got the "PGSERR" randomly , and error code is "0x00040000 "Any comment , thanks HAL_FLASH_Unlock(); __HAL_FLASH_CL...
I'm noticing some odd behaviour in the QUADSPI peripheral on the STM32H743. When I use the automatic status polling feature in quad mode it appears that the 1st query works as configured, but subsequent queries are strangely incomplete.What I mean by...
Hi, I am trying to receive 19 bytes in UART in DMA mode. I have configured both the peripheral (DMA_CCR_PSIZE) and memory alignment(DMA_CCR_MSIZE) as byte. When I Enable the UART receive in DMA mode, I encountered with Hardfault exception. After debu...
Hi,I'm trying to generate a serial data pattern in STM32H753 for WS2812B LED chip. I did it before with STM32F2, as the TIM, GPIO & DMA2 are within the same data bus matrix, i'm able to use TIM module events as a trigger event for DMA, and start movi...
Hello everyone ; Please if someone from ST could confirm : We have a shortage of stm32f429 and the given lead time is about 80 weeks ; so our production will be stopped for 1 year; to solve this we decided to revise the design of the board and cho...
When I use Keil MDK V5.30 build target file,it cames. So how can I solve it.
We cannot purchase microcontrollers. No distributors. Nowhere. When will the problem be solved?
The solution was to hard reset the SPI module using RCC_APB1RSTR register.HAL includes macros for this:__HAL_RCC_SPI2_FORCE_RESET(); __HAL_RCC_SPI2_RELEASE_RESET();With these it completely resets and can be initialized again!I'm using SPI slave mode....
