ADC-DMA Test can't work on STM32H757 i-EVAL Board

I want to test ADC-DMA function on STM32H757 i-EVAL Board. But the result is DMA transfer error. I just copy the example code of STM32Cube --- STM32H743I-EVAL\Examples\ADC\ADC_DMA_Transfer to my STM32H757 project.When execute the code, it occurs onl...

STM32G4xx FDCAN Delay Compensation

A little something I have noticed today. I have been developing an application which is using the G431 and uses FD-CAN. My code was working in External Loopback mode such that a CAN message of my choosing was being correctly received by an external d...

Im trying to connect a flight controller/esc board to an application im using on my cellphone but when i plug in the FC and try to connect it will not read the port connection?

UART not receiving anything

Hi I have a code bellow:static void MX_UART8_Init(void) {   /* USER CODE BEGIN UART8_Init 0 */ GPIO_InitTypeDef GPIO_InitStruct = {0};   /* USER CODE BEGIN UART8_MspInit 0 */   /* USER CODE END UART8_MspInit 0 */ /* Peripheral clock enabl...

DAC output differs between Channel 1 & 2 on Nucleo-F446RE

Hi :) I found something quite strange, it seems that:1) On DAC Channel 1 - the output buffer does not work (a 10kOhm load brings the voltage down), but it's output is inverted (as expected)2) On DAC Channel 2 - the output buffer does work (maintains ...

Java on an MCU

seems like the chances of a JVM on an MCU is a nightmare?research show java is supposed to be cross platform, however it makes sense to be able to embed the virtual machine without difficulty first. I can’t even find a successful case online except b...

STM32H745/755 clock setup with LL libs doesn't work properly (CubeMX)

Hi guys, I tried to setup frequencies for cores to max which is possible. The code for LL was generated, compiled, but the actual frequency of core M7 (480 MHz) looks much lower than 480 MHz. LL generated codevoid SystemClock_Config(void) { LL_FLAS...
