Hi,I want to use the ETR to count pulses and set a second timer, so every ... seconds the value from the ETR counter is red and renewed like discribed in this ExampleSTM32 Frequency Counter – LAB10 https://deepbluembedded.com/stm32-counter-mode-examp...
I'm trying to send data via USART to a serial monitor (i'm following a course) but i can't see it's receiving the data, the course is creating its own library manipulating registers.void UART2_WRITE(int ch); int main(void) { //enable clock to g...
Trying to synchronize in time three different STM32F446RE MCUs. I first tried to look how internal oscillators drift compared to each others.The datasheet says that the precision of the oscillations are of 500ppm (parts per million). So every 1000000...
Hello,I'm trying to implement a UART DMA data transfer in STM32F429. I face the following problem.I'm using custom-made Python to receive and transmit data over the serial port. I am sending an unknown number of bytes from my computer to MCU. So, I'm...
Hi All,I am new in development of controller run in low power mode and resume, I used the STM32F072RBT6 microcontroller. In my code CAN Peripheral with extended data frame( 1 Byte data) format and three timers are used.Now, The requirement is when...
Hi All,I don't managed to send char on USART3 with the attached project.I was wondering if someone had already detected issue in using USART3 Thanks in advance
In the reference manual STM32H7 (version July 2018) in chapter 37.1 - figure 343 for the clock source it says "CK_TIM18 from RCC".Problem: If I look for "CK_TIM18" in the complete manual, this name appears ONLY ONE TIME, here in this chapter 37.1 fig...
Hi i am using stm32H750VB as the IC for my project.I need to detect sudden power shutdown .I.e., i need to use PVD mode for detecting the sudden drop in voltage and save the EEPROM Contents.I need to use PVD using external analog voltage PIN RB7. But...
