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 ...
What could be the reson that the software on the Discovery board does not start?
I have a STM32F407 discovery board on which the flashed software does not start when I connect it via the USB connector. The board is found by the PC (Windows, the folder is opened automatically), the LEDs on the ST-LINK light up, but the flashed sof...

how to write SN for hundreds MCUS? i know j-flash can write fixed bytes,i need to write custom 10 bytes SN which has its own generation rule
[STM32F429 Flexible Memory Controller (FMC)] Is the write operation blocking for the CPU? (NO BURST MODE)
I couldn't find this info on the Reference Manual, maybe because it is trivial, in case I'm sorry. When the CPU performs a single STR within the FMC address space, is it blocked until the entire write cycle of the peripheral is complete, or it only w...
Frequency limitation when trying to generate a 2us period on a Timerfor the STM32F7.
Hi, I'm trying to generate a 500KHz counter on TIM1 on the STM32F7 to trigger an ADC conversion and I'm currently having issues as it seems to top out at 360KHz. I'm toggling a GPIO pin with a scope to the input and simply changing the Period on the...
