Resolved! PUPDR in GPIOD - default values are wrong
In the manual it states, that reset value is 0x000.., and that 0xFFFF... is reserved. But when debugging, i see, that it is 0xFF... . When now assigning a new value to it via HAL_GPIO_Init(), the register does not take the new values.Hold on!I just f...
ADC multichannel DMA with Freertos on STM32H735G-DK
I have tried many things but cannot seem to get ADC multichannel DMA with Freertos on STM32H735G-DK working.I have setup the ADC to use DMA following many tutorials. I have set up a task to start the ADC with DMA, but the conversion complete callback...
Resolved! How To Achieve Fast Data Write On GPIO Port With The Fixed Frequency Between 5MHz to 10MHz?
Dear Experts,I need your help, I am interfacing 16-bit DAC LTC1668 50MHz with STM32F411CCU6. I have used Timer 4 as 1MHz CLK for DAC, on Half Pulse Complete interrupt I update the GPIO Port (Port A A0-A7 are D0-D7, Port B B0-B7 are D8-D15). But Facin...
What are the exact pins and ports for UART1, UART4 in STM32h745I-DISCO board?
Hi Team,I'm working with the STM32H745I-DISCO board for UART communication. As I'm working with UART, I'm able to get the data through UART3 from STLINK. But I also need same communication through UART 1 and UART4. Could you please help me with the e...
