Hi, I have RS485 full-duplex IC on my board with outputs from the IC wired as half-duplex. DE/RE pins connected to GPIO on HPS are used to controll the transmission instead of RTS/CTS pins so I cannot use the RTS/CTS approach which is already supported by the driver. I would like to ask if there is already some driver or framework how to toggle dedicated pins during the switch between Tx/Rx. Or do I have to implement this pins toggling into the driver by myself?
G'day Michal You should be able to export the uart to the fpga and use loanio to remap the hps gpio pins so that you can use the driver as is. I did similar to get a PPS signal from a GPS module into the hps uart on the correct signal for gpsd to work. -- Regards Phil Reid _______________________________________________ Rfi mailing list [email protected] http://lists.rocketboards.org/cgi-bin/mailman/listinfo/rfi
