Decoupling capacitor placement
Hi,I am currently optimizing some designs and started thinking about decoupling capacitors. As far as I know, it is a rule of thumb to place "one 100 nF capacitor per V+ pin".In the attached document, ST recommends exactly this. Let´s look at the doc...
STM32H747i-Disco LCD Driver Issue
I have been working with the STM32747i-Disco and the STM32F769--Disco boards. Both have the MB1166-A09 LCD daughter board attached. I have implemented the LCD_DSI_CmdMode_DoubleBuffer example for both. Teh H747 platform took a little more work as the...
Resolved! GPIO outputs are in high-impedance state
I have two of the STM32H747I-DISCO boards. I have used STM32CubeIDE to create a simple project for the boards. I followed AN5361 and am able to debug and see the CM7 and CM4 cores running.I've added code to toggle the board LEDs (port I) but don't se...

Resolved! STM32H747-DISCO cannot run at 480MHz
Hi,I have bought the STM32H747-DISCO kit for testing and I want to test at the max frequency (480MHz). I'm aware of the requirements for the 480MHz, I have followed the user manual:Desoldered and soldered relevant SBs for LDO operation.Updated the co...
Nucleo ST32F4F439ZI will not run on VIN External Power
We have a very time-sensitive project that uses the Nucleo ST32F439ZI Development Board. It works, boots, and emulates just fine when powered from USB however, when externally powered it gets stuck and will not boot properly or work with the USB ST-L...
