Programming external STM32H750 MCU using NUCLEO-STM32H743 board

2021-01-31
I have NUCLEO-STM32H743 board and some STM32H750 MCU-s. As I can see in the board manual, it has on board SWD interface. I want to use that board to program and debug aforementioned MCU-s and, as far as I can see, this should be possible. Where can I...

Power supply scheme for STM32H750

2020-12-03
I'm working on PCB with two MCUs, and I'm not sure how to connect power supply lines. Even after reading the datasheet and RM0433, I still find it confusing. Like, which one of the VDD33USB or VDD50USB should I connect and why? Do I connect both? Or ...

Can't get a stable VGA output on Nucleo-H743ZI2 board.

2020-11-30
I have connected LTDC output to VGA monitor input and the picture is flickering. I've connected HSYNC and VSYNC signals, ground pin and only the highest R/G/B bits over 500 Ohm resistors to R/G/B input signals of the monitor. I've set vertical/horizo...

Slightly overclocking STM32G070 without external oscillator

2020-11-25
It runs at 64MHz, and I need it running at 65 MHz. I've managed to create 65 MHz clock in PLL using multipliers/dividers in STM32 Cube IDE, but I'm not able to test it before I order the PCB-s, which I'm not intending to do before I confirm this woul...

STM32G070RBT6 effective speed when running on 64MHz

2020-11-21
I've read in RM that, when running on 64 MHz it has 2 wait states, meaning that 1 cycle instructions execution takes actually 3 cycles. If I understand this correctly, that means that the effective speed is actually 21.3 MHz? What use is there using ...
