#139433 - many have tried - and failed Responding to: ???'s previous message |
I want to let some pins low when I start my
machine. the presumed 'fix' is (pseudocode) 0 jmp reset reset px = 0; all well and good, but you will still have the pins high while the supervisor (if you do not have one add one) resets. the only reliable method is http://www.8052.com/forum/read.phtml?id=139426 "use an invertor e.g. 74xx04" Erik |
