stm32F746 Custom board, capacitive to resistive touch LCD
I got my custom stm32F746 PCB Working! It is based on the STM32F746G-DISCO. So, for the first revision I used the same capacitive touch lcd used on the Disco. So that all works! But I need a resistive lcd, so I designed in a TSC2046IPWR controlle...

I m trying to communicate through USART with my NUCLEO-L476RG but the STM console is displaying nothing. I have created a simple project:I m overriding the __io_putchar function:int __io_putchar(int ch) { if (ch == '\n') { uint8_t ch2 = '...
Resolved! Problems using PTH components instead of SMD?
I am making a stm32f411ce board and I want make sure everything works because it's very expensive to order a pcb in my country. I want to use components like Hc-49 8mhz crystal(and dt-38 32.768khz) oscillators with ceramic PTH capacitors, the only sm...
[DEV_CONNECT_ERR] When trying to connect to a STM32H747-DISCO
HI there, I own a couple of STM32H747-DISC0 boards for a year. I been using them without issues debugging but when started a new project, I do not know what went wrong that cannot access to any core from any ST tool (CubeIDE or CubeProgrammer).No mat...
