i cant do anything with interrupts. ive already made the PCBs up for these circuits and the only interrupt pin is an output. i never thought i would need it

can you post your schematic?

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

sure, here it is.Originally Posted by mister_e
i spoke with a really clever electronics guy today about that capacitor thing mentioned in the last thread. he showed me the best way to do it but its not done in this circuit obviously.
the only interrupt pin is RB0 which is the 4th pin up on the left and thats in use on the first triac optoisolator
Edit: aparently the bmp is too big. sorry for the jpeg quality

no i meant a real schematic, not a board layout

oh, erm. i havnt got one. sorry

mm, so you could move what's on RC7 to RC5, and free BOTH USART pin? yeah some PCB mods... no harm, but bit of pain i agree..

i could but as i said ive already etched the PCBs as i didnt have any need to use the interrupt pin. any new circuits i do ill always use the interrupt pin as the serial input.
suppose if theres no other way to do it then i can just write my VB app to always send out so many characters
