STM32F746GDISCOVERY AN4760 pg. 58 How to proceed to program QSPI Flash memory only once... for IAR EWARM STM32Cube_FW_F7_V1.14.0\Projects\ STM32746G-Discovery\Applications\QSPI\QSPI_perfs My project, based on the above

I have 3 pictures 544K in size (ARGB). Please write in more detail how each time do not overwrite the data to QSPI during debugging. The reading of the IAR HELP "Linking using ILINK section" did not add to the understanding.Thanks in advance. Sorry f...

STM32F103VCT6,Serial port 1 interrupts, and simultaneously outputs data in serial port 1 and serial port 2. Serial port 1 stops sending after just a few frames of data are output, while serial port 2 still has data output.Is there a solution?

In the interrupt of serial port 1, data is output in both serial port 1 and serial port 2. Serial port 1 first sends data, then serial port 2 sends data. After serial port 1 outputs a few frames of data at the beginning, there is no data output, whil...

Hi, I use the core-g431kbt6 which I feed at 10 volts between the Vin pin and the gnd. I would need to connect with the usb via stm Studio to monitor some variables, but when I do the card is reset. Is there any way to avoid this reset?

confused about command declarations of QSPI flash memory for STM32F746 custom board with W25Q256FVEM QSPI flash memory chip

I am working on custom board STM32F7 MCU project with W25Q256FV quad SPI flash memory and according to the ST 5-Part quad SPI video tutorials, I copied all the necessary sections from public storage QSPI.c & QSPI.h files to my project, but based on m...

Why not replace Systick by hardware timer?

Recently a thought popped up when I had a look through interrupt handlers (Using HAL):As Systick handler gets called every millisecond (if not changed to something else) only to increase a counter, doesn't this unnecessarily waste valuable compute ti...
