please i need help with the attached proteus microcontroller simulation, the hex file load okay but when i press the key, the leds dont come on.
Also where can i find materials using proteus with the pic16f84a, thats the microcontroller that i have for now thanks
Hey! change the supply, I wish I knew how to attach what I did to make it work but I looked around can't find it and i don't have much time!
but just go to sources change the supply, remember that blue means logic level zero and red means logic level one, so watch out for those! if you don't get this email me at chieftsonga@yahoo.com and i will forward you the Schematic will relevent changes!
The ground is not connected to the minus of the buttery, you have placed the ground there but you haven't connected it.
Move the ground a little lower and draw a wire, then it will work.

Never expect proteus to connect pins just because you place them touching each-other in the schematic, you have to draw a wire.
Thanka all, i have done all the corrections the leds comes on but i get error messages which says logic contentions detected on nets #00004 to nets #00006 the simulation does not work the way it should
