The hardware is the STM32F407 that is receiving a request from a RS485 USB converter connected to my pc and the STM32F407 too that is transmitting to the pc. We are using the peripheral USART3 to receive and to transmit. With an oscilloscope I see ...

Hi Peter,with the following code variation I've the symbol "°" in the display. I don't know why I can't write == '°' and leave "°C" instead of =='?' and " ?C". If I do so the if condition is skipped.

modbus tcp/ip with stm32f407 and switch ksz8563rnx of microchip

Hi, using the USART I've seen that the hardware of the board expects the echo of the transmission on RX, the peripheral doesn't receive the messages that transmits. I've used CubeMx to set the peripheral. Could have I set some filter that prevent this?

Hi, I would like to print to the screen a string, reported below in Details, with the celsius degree symbol "°". However, I find other characters if I look to the screen. Is it possible to change alphabet with some option of the STM32CubeID to find "°"?
