the hardware, it should be made ?

You can connect the simulated LCD just like a real on with the Oshonsoft simulator.

I think the 16F877 has died.
someone has a small program with some leds
and tried to make sure that the 16F877 is dead?
thank

Can you read the program back from the pic using your programmer?
Try erasing the pic and reprogramming..

My Inchworm quick start poster on my site has a schematic and program to flash an LED with a 16F877

I program with winpic800 and icprog.
programming is normally ok at the end.
reading the 16F877 is also normally
with winpic800 and icprog.
when I delete the pic is also good.
reading indicates 3FFF ... ... so it's good 3FFF
but I do not understand why the pic does not work with any program! ?....

Use Mpasm to generate the hex file from the assembly code...

You can download Mpasm from Microchip's website

I use MPLAB v8
I never managed to create a. hex from a file asm
Here is what I do and every time an error

project wizard --> next...16f877 --> next --> indic.location Mpaswin.exe ..---> next
creat name project file ..next --->add file asm..--> completed

after
....project open file project...---> make ------> error !!

16f877 --> he died ?

Hard to help you with this we have not any thing to go by
There a lot of things that can go wrong bigest is you tried to build on the desktop
and not a C:\ myfile\firsttry.asm

I have had a 16f877 stop working and all it was is the osc stoped working. I wouldn't throw it away
it's more likely something your doing.

Pourquoi esce que vouz utilisiez un oscillateur externe?
Why are you using an external oscillator?

It's A 16f877 they have no internal oscillator

my lcd
http://www.selectronic.fr/upload/pro...nique/2337.pdf

a real say j' board many programs for 16F877 n'ais I never had a successful figure !
I do not know if this is the 16F877 or lcd that has a problem ?

how to say that c' is the 16f877 which has a prbléme or the lcd which has a problem?

thank

Imageshack - schematic

You building this on a solder less bread board right try two things first clip a gnd on the OSC to gnd see if that works If not remove c5 and c4 and see if that works

Alors,

I have found my issue of EP numer 265.....Sadly that issue is no longer avaiable so I cant download the source code...

Suffice to say, I built a project from another issue called Meleda, based on 16F84 that refused to work...So I wouldnt rule out a s/w issue...
