I am experiencing a vey long external interrupt latency up to 2 microseconds.Clock is internal PLL, 64MHz.void HAL_GPIO_EXTI_Rising_Callback(uint16_t GPIO_Pin){ if (GPIO_Pin == TRIGGER_Pin) { __disable_irq(); LL_GPIO_Reset...
Hello,we're also suffering from the general part shortage and are planning to switch some of the STM32 devices we use to a lower temp grade, as those seem to be better available.I'm trying to figure out what impact the switch from a grade 7 to a grad...
Hi, sir.Before I speak, I'm Korean so English may be wrong.But please help me... (T^T)I am using STM32H743VIT for project. And I want to save Flash memoty to some data.Sometime, It is return HAL_OK. So i can save some data in flash memory.but Most of...
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...
