[Bacnet-developers] Understanding AVR port

[Isaac C. <son...@ya...>]

     I'm new to BACNET and trying to understand the AVR port I see on file hardware.ods that some of Port B and C is connected to dipswitch and see the reference in main.c line 140 and 141.  I also see some led on/off  reference in rs485.c.  I also see that there is a file name ai.c which I presumed is analog input and somewhere in the avr port files there should be an analog to digital conversion referencing AVR hardware ports but I could not find this reference and I don't see it either in the hardware.ods where this would be.  I see that ADC4/ADC5 TWI/I2C is reference but I could not find in the avr directory where the actual analog to digital conversion is done.

     Thanks for all your help.


Sonny
