UART RECEIVE PROBLEM / STM32G061C6
Hi all,
I am using a STM32G061C6T6 MCU. I'm trying to contact Nextion HMI. My data sending is successful, but I can't get any data. I couldn't run any of the Pooling and interrupt methods when receiving data. When I follow the RX pin with the oscilloscope, the data comes, but I can't read it with MCU.
I tried the display on the Nucleo-F103RB card with a simple HAL code. I can read the data from the screen. Do I need to do a special operation on this MCU(STM32G061C6) to be able to read with UART? I'd appreciate it if you could help me.
