Alex Vilson said: > And what about configuration bit from this 16F874? LVP=? WRT=? I'm using the following settings: HS osc (4MHz xtal), WDT off, PWRTE on, BOR on, LVP off, Data write enabled, Code write enabled, Debug disabled, Code Protect disabled. Unfortunately I can't confirm this as both of the chips I put Wloader on are now dead... These are the defaults from the Wloader code.
