UART flow control - which way up?

Postby frackers » Fri Jul 14, 2017 2:11 am

I'm talking to an ESP WROOM 32 with an STM32F303 and using the hardware flow control at both ends. I can't work out which way up the flow control signals are into and out of the ESP32 resulting in no data going anywhere!!
