Hello everyone,I am struggling with a problem that has not been solved before. Perhaps someone could be found who would be able to solve it. The issue is with the operation of the interrupt for receiving a character via USART. The interrupt is not re...

Hello everyone, I have a problem with sending a variable of type string using the USART interrupt in order to control an SG90 servo with PWM. Initially, the idea was to use keyboard key presses to make the motor rotate either to the right or to the l...

I am working with an STM32F303 and trying to generate a PWM signal on TIM3, Channel 1 (PA6). Everything seems to be correctly configured (verified in the debugger – registers appear correct), but there is no PWM signal on PA6. The function responsibl...

Hi everyone,I'm working on UART communication with an STM32F303RE, and I'm experiencing an issue with data reception. I'm sending the character 'A', but I'm receiving incorrect values (F8F8 instead of 0x41).I tried changing the APB1 prescaler, but th...

Hi, I’m having trouble reading measurements from the ADXL345 using SPI. I’ve attached a picture from the debugger that shows a view of the variables. The SPI is configured as master full duplex, and I’ve included a screenshot showing the SPI configu...

@Tesla DeLorean At the beginning of the program execution, I successfully sent the letter. However, the USART is not receiving the letter I am sending for interrupt. The registers in SRFs debugger mode do not show any Noise or Framing type error bloc...

@waclawek.jan According to your recommendations, I fixed the interrupt handling code, but unfortunately, I did not receive the desired letter from you.void USART2_IRQHandler(void) { if(USART2->ISR & USART_ISR_RXNE) { message[currentindex] = USA...

@waclawek.jan A diode is connected to the timer’s output pin. I tested everything using HAL, and it worked fine. In the main loop, I changed the duty cycle to turn the diode on and off.In the future, I plan to control a stepper motor, and I want to b...
