Hi,

I'm afraid it's not something that I is exposed - but presumably you could just attach a signal diode (so only 0.3v drop) between the STM32 TX pin and the serial line, so it's only ever capable of pulling the signal down?

You could take a look at https://www.espruino.com/STM32+Peripherals though as it may be you can set the STM32 up as normal and then just poke a register value in the UART to enable the half duplex mode?

Hi Gordon,

Thanks for your response. I managed to activate half duplex mode by poking the correct register as you suggested and all seems to work as expected.

Thanks!
