Hserin with Instant Interrupts.

[skimask]

I'm going to try your method of toggling the LED's Skimask, never seen it done like that, Thanks.

I like that method of using the heartbeat because it allows for an easy change of blink frequency. The LED 'attached' to a timer works also, but it only tells you that the timer is running and an interrupt is working. Generally, I use 2 heartbeats, one for a mainloop, and one for a timer. Mainloop says the program is looping, timer says the PIC is actually running.

From what I see it's mostly a matter of setting up the defines and running getbytes?

Is this the barebones of what I need to get data in/out of serialdata?

As long as data is at portc.7 it continuously runs in the background as an input, loading serialdata while any other code is executing?

I can then sample serialdata when I need to in my code?


DEFINE LOADER_USED 1
DEFINE OSC 4
DEFINE HSER_RCSTA 90h ' enable serial port,
define HSER_TXSTA 24h ' enable transmit,
define HSER_SPBRG 25 ' set baudrate to 9600
DEFINE HSER_CLOERR 1 ' automatic clear overrun error

TRISC = %10000000 ' PORTC.7 is the RX input, PORTC.6 is the TX output


' Serial communication definition


Getbytes:

While RCIF = 1 ' clear the buffer
HSERIN 100,error,[Serialdata] ' take it
hserout [serialdata] ' send it
