DMX512 Problem ..Schema+Code

[mister_e]

I already said...

AND as you dont use any HSERIN/HSEROUT, the DEFINE HSER_xxx are useless. You need to write the right value directly to the SPBRG, RCSTA, TXSTA register

so begin with...

RCSTA = $90 ' Enable serial port & continuous receive
TXSTA = $24 ' Enable transmit, BRGH = 1
SPBRG = 4   ' 250 KBaud @ 20MHz, 0.0%
