Hi everyone!
I am trying to send some HEX data to a printer module using STM32F4 Discovery board, UART. in cubeMX I defined some pins as TX, RX and CK. when I generate the code, I can not see any sign of these pin!!! why?
also when I use function HAL_UART_Transmit(), does it send data to TX pin?
thanks everyone!
Again, that has nothing to do with Keil!
The HAL is ST software - not Keil's; not ARM's.
What does the documentation tell you?
If ST's documentation is unclear, you need to ask ST for clarification!
