My H7 board has a strange issue: if I connect it to USB, Windows recognizes it (PRODUCT ID & VENDOR ID are correctly shown) but no communication (by CDC_Transmit_FS()) happens: CDC_Transmit_FS reports me BUSY_USB.If I reset (by the pushbutton) my boa...

Hello, I have a doubt about the voltage tolerance of STM32H743: looking at Stm32h743bi.pdf, LQFP176 pins are numbered 1,2,...,176, while CubeIDE gives me PA1, PA2, PB1, PB2.... etc.So, how can know if my UART3 pins (PB10 & PB11, Alternate function P...

I have a question about the electronic config on my stm32H743 board.At the moment, I have a digital pin that reads a switch position:Now, I'm going to use the NO pin to drive a 5V OMRON Relay (with a led and a diode on the coil terminals) to drive a ...

Unfortunately, it is not possible to access debugging functions: it is a custom board and I can program it by USB (there is a switch to set "Config Boot System" and to allow me USB programming by STMCubeProg), but STLink / JTAG /SWD Interfaces aren't...

Due to the R2 resistor, the relay simply cannot operate...I can bypass the R2, but I don't know if the 160 Ohm resistor is too limited and it causes damages to my pin.Can someone help me?Thanks and best regards

Hello Tesla DeLorean and thanks for your reply. I didn't notice the "Pin Name (function after reset)" :o column, so I wasn't sure it was 5v tolerant.In that case, my pins should be 5V tolerant.I have to connect my stm32 to an RS232 -> RS485 industria...

If I have correctly understood your problem, I think you have to modify your ScreenXXX.cpp and insert :dynamicGraphXXX.setGraphRangeX(min+range, max+range); range=range+9;I never used this function, but I think it is the right one (.. I hope) 

I think the problem is in the osDelay() values (do I need to increase them?) but I'm not sure how to define these delays: I set TouchGFX to osDelay(100) without problems but between ADC function (about 5-6 ms to complete the function) and USB to moto...
