Issue with the 4-wire resistive touch interfacing with smt32h743zi
i have written a driver code to run 4 wire resistive touch panel. I use only 1 adc and change its adc channel during runtime. Like i set X+ and Y+ as output high by default and X- and Y- set as low by default and set X- and y- pull down to make ADC r...
Resolved! STM32H7 - MPU Configuration
Hi All, I was testing my new STM32H746XIH6 board and met the post below by @GSpre.1 during a search about SDRAM performance. GSpre.1 - Performance characteristics of SDRAM on STM32F7508-DISCO board I don't have a lot of time to read MPU documentatio...

Resolved! Periodic PC sample packets via DWT
I am trying to persuade an stm32F412 to provide Periodic PC sample packets.Reference manual RM0402 implies it is doable (Configure DWT as a PC sampler)The "Cortex-M4 Technical Reference Manual r0p0" says "You can configure the DWT to generate PC samp...
STM32U5 FDCAN permanently retransmitting with retransmission disabled
Hi, For a reason that I cannot explain, the STM32U575ZI (on the nucleo board) is sending a CAN bus message with infinite repeats and 100% bus utilisation, but I have repeated transmission turned off (DAR bit set to 1) and I have confirmed this using ...
