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...

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...
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 ...
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 can I use the ×××_DeInit()? And where it should be used?
I have been following a course Mastering microcontroller with STM32, and the emphasis of this course is to walk the student through the architecture of STM32 MCU's, and develop the driver's for GPIO, SPI. I2C, and USART from scratch. I have an STM32F...
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
