Does anyone know if the LPC2100 series has the capacity to do IrDA without an external IrDA encoder/decoder? Some newer MCUs like the STR911/912 series have UART's which can do IrDA encoding/decoding as well (requiring only an LED transceiver). However it appears to me (at first glance) that the LPC2100 series doesn't have that capacity.

Can anyone give feedback from implementing IrDA with the 2100 ?

Hello,

the protocol starts by default with 9.6kbps and that is possible to do
with bit banging. If you want to go to SIR full speed, which is
115kpbs you have this 3/16 pulse form with 1.63us pulse width, should
be possible to do.
But I saw, that the new parts LPC288x for example do have Irda support.
Challenge is more the IrDA protocol stack itself.
Here is a starting point http://blaulogic.com/pico_irda.shtml

Im curious too if there is any way of manipulating and interpreting
the IrDA signals on LPCs that don't have the endec, without using an
external endec.
