Posted on July 13, 2018 at 05:12Hello,I am using the scanf with CubeMX 4.26, I want to read the input string with white spaces so I do something like this:/* My variables here */char console_input1[20];char console_input2[20];/* My code here */print...
Posted on July 07, 2018 at 16:52Hi All; I would like to know when I use HAL library for parity. I setting please see belowhuart1.Init.Parity = UART_PARITY_ODD;When I setting 'UART_PARITY_ODD' and 'UART_PARITY_EVEN' is not working.I would like to ...
Posted on July 13, 2018 at 03:19Hello all, Perhaps, you can shed some light on my issue I'm seeing. I have a board with a STM32F413RG microcontroller, I'm trying to control a DAC for multi outputs but I am having trouble getting the F413 to gener...
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 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 ...
