Hello,we want to build a system with STM32H7, hopefully one of the new up to 480 MHz devices. And we really need a high clock of 400 MHz and above. On the other hand we need low power and we use ADC and DAC, both requiring a 3.3V Vref.Now my question...
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",""); ...
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...
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...
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 ...
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?
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...
In STM32F429 Discovery Board , CAN Communication is not happening , Tool used,PCAN.
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...
