Hi Rick,


it is of course possible, but (the big BUT) you have to write a new bootloader which presets lets say 38KHz as carrier frequency for your newly soldered IrDA module.
Hence you need a ISP programmer, hence your current Programmer for RS232 using 36KHz still does not work anymore.


As a 2nd solution you could use a "Daughter Board" where your current IR transmitter and receiver are soldered on. The same you could fabricate for the i.e. 38KHz variant (implies this is really the frequency used by your phone) and this two doughter boards can be plugged to your board somehow.
Now you could flash the Asuro using the "old" components and communication with your phone would go with the "new" board.


In this thread you can see a PCB daughter board as i mentioned above. It is meant for distance detection, but you could use the same principe for your purposes.


What do you think?



Greets,
