PIC Help! MY led Keeps Flashing and dimming when displaying the message HELP!

well this won't help,but whats the point of using a basic compiler if the code is in asm? you would get more help if it was in the pic basic language.

I second that - the reason I bought PBP was because I never was very comfortable with ASM - just too dumb, I guess.

BTW, I find it SO much easier to get things working now!

Sorry for the hijacking - we now return you to your regularly scheduled thread!

Hi Jack,
It sounds more like you may be experiencing "current limiting" where your power supply is not providing enough current (amps) to your circuit. Have you checked the voltage before you power everything up and then what the voltage is when the circuit is operating? A schematic of how things are wired would be helpful especially with what parts you are using. An alternate test would be to send fewer characters and there is also the possibility your LCD display is bad? Maybe just send the letters TEST? Flashing and dimming is typically an indication of a power or wiring problem. Best, Ed
