errata
i was thinking that the "GP2W0120YP0F" has no internal manchester
encoder/decoder
i have imagined that GP2W0120YP0F was just a infrared transceiver, i
mean "infrared tx diode" coupled wth "infrared rx photo transitor +
operational amplifier" ....
but ... reading the GP2W0120YP0F's datasheet i see it has an internal
manchester encoder/decoder
so the GP2W0120YP0F.{rx,tx} should be directly connected to the ARM
cpu serual port
so it should be possible to unsolder GP2W0120YP0F in order to export
{gnd, tx, rx}, to be coupled with 3.3V-RS232-level-shifter
(or not ?)
