Posted on July 11, 2018 at 11:49Hi,I am using the MCU STM32F439 in my Project. We are using I2C which connect other slaves with 5V logical level.But the STM32F439 says the I2C port in the STM MCU is not a 'true OPEN Drain' port. Can connect an 5V ex...
Posted on July 11, 2018 at 11:53My setup: STm32L053 nucleo and custum board with STm32L0. I am running a scan from nucleo borad for all possible I2C slave devices address in order to obtain the address of slave device ds1337.Both boards are connecte...

Posted on July 12, 2018 at 19:05Hi,I enabled the ADC DMA inside the Timer2 interrupt, and Put '1' for a GPIO PIN, as follows:void TIM2_IRQHandler(void) { HAL_GPIO_WritePin(GPIOA, GPIO_PIN_0, 1); HAL_ADC_Start_DMA(&hadc1, (uint32_t *) buffer, 100);HA...
Posted on July 09, 2018 at 22:43Hi,I am trying to find some example for DMA configuration on Nucleo144 (STM32H743ZITx).A DMA should transfer data from GPIO port pins to memory by SYNC signal provided by external clock (EXTI2).Did not find something ...
