Topic: Future arduino designs: provision for RTS_DTR? (Read 750 times) previous topic - next topic


Hi all

I wonder if the future arduino designers would consider adding a PCB pad/pin for the RTS (pin 3) and DTR(pin 2) as it comes out from the FT232. At present the DTR line is used for RESETing the arduino but the RTS line is not used at all.


Well a lot of Ham radio software provide functionality through both DTR and RTS eg one can be used to send morse code and one is used to enable push-to-talk functionality .

The arduino mega provides a jumper to disable the reset function of the DTR line and thus one can use the DTR line from this jumper for a specific purpose. Unfortunately there is no track or connection for the RTS line at all. It would be nice if the nano or one of the other version catered for both of  these.
