The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
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...
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?
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
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...
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...
