ADC accuracy problem
I am sensing the voltage using stm32f103c8 module.using Keil micro--vision 5register level codingcode:#include "stm32f10x.h" float av,volt; int main(void) { // SEND A CLOCK SOURCE FOR ADC //LcdSend2StringWithDelay(50000,"Start Clock",""); ...
Unknown pulsing on STM32L073RZ
Hi there,I'm working with an STM32L073RZ CPU and Mbed OS 5.12.0 and experiencing an issue that I'm not quite sure how to describe. The processor gets into a state whereby it oscillates a pin (PA_5 which is setup as an InterruptIn that pulls down) and...
STM32H7 hangs when trying to erase bank 1, sector 0 shortly after reset
Using an STM32H753, I have boot code in bank 1, sector 0 (0x08000000) that detects and jumps to application code in bank 2, sector 0 (0x08100000). In the application code I am trying to erase and rewrite bank 1 sector 0, but the MCU locks up (with no...
Problem with STM32F4.7 External Interrupt
Dear All,i configured an input pin as external interrupt with rising edge detection and pulled it down internally.i apply a pulse train which it sets and resets within the time that the interrupt is disabled.i expect that the ISR executes when it is ...
MSI with LSE auto calibration accuracy
Has the MSI with LSE auto calibration a sufficient precision for the 1Mbit CAN bitrate?What is the accuracy compared with a crystal PLL clock?
STM32F103 - PB3 just doesn't work as GPIO
Posted on December 14, 2016 at 10:27Hello,did anyone ever manage to get PB3 working as an I/O port on an STM32F103?I am having a hard time with the F103VB where I need PB3 as input - no matter what I try, PB3 simply is returning a 0 value.AFIO->MAPR...

SPI not working with MCP6S21
Hi everyone,I would like to use a simple VGA (MCP6S21) but still not reach to do it.The datasheet is available here : http://ww1.microchip.com/downloads/en/devicedoc/21117b.pdfI'd like to put a +2 gain, the signals (SCK,MOSI) I transmit seems to be O...
About UART communication between PC and STM32F4
Hey, I am trying to connect my STM32F4-DISC board to PC via USART. It is a very common and basic example like sending a string to PC COM port which is covered by lots of tutorials on the web. But my question is,I first used this product and directly ...
