I'm trying to setup IrDA communication on UART0 (K60N) but having some difficulties.
Maybe someone can help me out?
1.) I'm wiring UART0_TX to the internal photodiode by setting PTD7 to ALT3 which sets PTD7 = UART0_TX.
2.) Now I want to UART0 to input from the internal photoresistor PTC6. Therefore, I guess, I somehow need to set PTC6 = UART0_RX.
But how do I accomplish that?
Since PTC6 is hard-wired with the comparator CMP0_IN0, I rather have to wire CMP0_OUT = UART_RX, is that right?
So, what are the correct Pins to be wired together?
By now, I found out the following:
There are two pins, PTC5 and PTB20 which I can set to ALT6 to get = CMP0_OUT.
Does that help anyhow?
And there are 4 Pins, which can be set to UART0_RX:
=> PTA1 ALT2
=> PTA15 ALT3
=> PTB16 ALT3
=> PTD6 ALT3
But I still have no idea how to wire UART0's input with the photoresistor's output, i.e. how to set CMP0_OUT = UART_RX.
Any help would be much appreciated!
