pic16f88 Serial questions (hserin/hserout, etc.)

Hello harralk,
put all this code in UPPERCASE letters

DEFINE hser_rcsta 90h 'set receive register to receiver enabled
define hser_txsta 20h 'set transmit register to transmitter enabled
define hser_baud 9600 'set baud rate

make sure your arduino is sending data TRUE not inverted, you CAN invert it with a single transistor, be sure to pull up the Rx input with about 4.7k resistor. I know there PICs in the family which are not so fussy, but don't know which ones they are.

Does the RX pin (pin 8) need to be shorted to INT (pin 6)? I've seen schematics where the pins are shorted, but nothing in the documentation I've seen says this needs to be the case for what I'm doing.

No that's a different interrupt, & on the subject of interrupts, I suggest you get some, try ON_INTERRUPT goto serial then set your intcon register . . . or use Darrel's instant interrupts and let them do all that brain damage for you and get free use of mighty fast assembly interrupts (THANKS DARREL) !.
