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...

Driving 5V bus transceiver with 5V tolerant pins

Good evening (o;I know that most GPIO pins can be driven from 5V devices...But how about connecting a 5V bus transceiver? Is that also save?Or better to use a level shifter in between?Reason for asking: Project involving SN75160/161 bus transceivers ...

How to generate exact number of pwm pulses?

hi, I am working on a stepper motor driver with stm32f407. Facing a challenge in generating exact number of steps for driving the motor. Now what i have done is, i shorted a pwm generating pin with input capture and stops the pwm generation once the ...
