Normally I use ST-link for programming. But I can not see data in serial port on computer. I use TMS,TCK,RST pins for programming. I would like to solve this issue for my new design. Could help me please? What I need to learn exactly ?

Hi everyone, I am confuse about I2C pull-up resistors. I use 4 I2C sensors. I am not sure is it true that pull-up resistors count. I use every sensors for pull-up resistors. If I use just one I2C port (I mean one port for all sensors) is it enough?

Thank you so much for advice I will work on it.

I mean programming STM32G474 from programming circuits. Programming circuit could be has a STM32F103.

Actually, I just want to make my own programmer circuit for STM32G474RET6 MCU. Problem: I do not want to just programming and debugging like ST-Link. I want to read data from serial port too. But ST-link doesn't have any RX/TX pins for that.Any idea...

Hi, I do not understand one thing. How can you decide value of resistors? I use STM32F446RE so, Can I wire SD card socket (I mean just connection side) directly my microcontrolller with this pull up resistors?

Thanks for your return guys. :)

I want to use ST-Link as a debugger and seri port reader. Any one know about it? Please help me.

Hi ST community, I would like to use CH340G USB UART converter for programming STM32F446RE Microcontroller. How can I do this? Any advice or idea about this? Thx a lot. :)

Also, I heard "Pull-up resistors are not require because STM32F already have one." is that true? Please help me about it. I will be really appriciated.
