Picpac is now silent   Message List  
Reply | Forward Message #445 of 681 |
HI Group,
After completing my Picpac assembly, I was eager to load a
packet monitoring program, I located a file in the group files
named "Packet.asm", after setting up HyperTerm and seeing the
01> on the screen I started loading the file using send a text file.
Picpac never responded fact is,
It's dead. Picpac is silent and displays 2 rows of blanks.
Can the PIC16F87X be reset?
Is it the program I loaded the problem? It's from the DECODE1
folder.
Or do I have another problem?
I could have had a problem before loading, never seeing another
Picpac I am not sure, What I mean
Is on the LCD on start up displayed the words PICPAC to the extreme
left in the upper row and the contrast was poor the letters were
very faint at the best position of the trimmer.
Since the failure the display is dark and crisp, with no letters, no
tones, the red LED is lit.
Thanks my direct mail is aa1pi@... 73 Bob

Looks like you loaded an ascii sample source code file. What you want is an assembled 'hex' file. Loke in the FILES section for a folder names PIC-TRACK....

Kevin, when the PICPAC has some bad code, it will appear to be dead. At least you are getting the black lines. With power off, hold down the two black ...

I also get two rows of blocks on the LCD; rows 2 and 4. But when looking at the serial port every thing seems fine. The Boot loads are all ok. I've tried...

The classic problem with the LCD is that you accidentally break the Resistor array when assembling.... Look at the back of the display module and measure the...
