Serial On Digital Pin


#1

Hi Guys… hello! :smiley:

I bought this GPRS Shield (http://garden.seeedstudio.com/index.php?title=GPRS_Shield_v0.9b), but I need a class that “emulates” a serial communication over Di7 (RX) and Di8 (TX).

Using software UART for GPRS is a very bad idea. Just wire your shield to one of serial pins

Good Gus…

But, Digital Pin 0 is COM1 IN, this is the same as TX ? or RX ?

Thanks!!

by definition, IN is RX (recieve) and OUT is TX (transmit).
