start up problem
hello,
i have written a pulse generator program (my first) and it runs perfectly in mplab simulator, but when i plug chip into hard ware it only runs sometimes. i have to turn supply on and off. crystal runs always (20mhz) and once running i can manual reset fine (mclr to gnd) is this hardware or software? mclr has 100nf to ground and 100k to 5v. 5v is regulated and has filtering caps. thanks for any replies.
