Hi All,
I'm making some small 4 channel 240Vac light dimmers to help out a
local school. I've already made the PCBs and have used a 16F628-04P
to control each one. I've included a 6 way DIP switch, 4 TRIAC drivers
and a zero cross detect via RB0. What I need to do now is write some
code for 'em! Does anyone have any good tips for phase control? I was
going to use the RB0 interrupt to detect the zero crossings and timer 0
to delay the phase firing from that point each time. I am going to use
the hardware UART with a RS485 driver/receiver. Sound OK so far?
Any good suggestions or pointers would be appreciated.  :-)
Regards...
