Hi to all,
Just got a PIC circuit built and programmed the PIC but got an error!
The configuration says 3BF9 but when it writes that it comes up with an error saying the config is 3BFF!
The PIC is a 16f84 and I have successfully programmed it before with my first program which was just a simple LED flasher, and that worked OK. However that program was a lot smaller than the Rev Counter program that I'm trying to do now so I wondered if a small part of a PIC can be faulty, maybe unable to be written correctly?
The program I'm trying to use is the RevMaster Firmware Zip at http://www.jeffree.co.uk/pages/tachometer-pcbs.html
I'm using the Velleman Pic Programmer with the Velleman Kit 8048 VM111 rev: 2.6.0.
I have built the circuit from the site on PCB and checked it many times, though it's got so few components on it that its fairly easy to check, and I cannot find any fault, the LCD is new and is the 2 x 16 line one that is used on the site.
I have tested with and without the slotted sensor which is on a separate plug in board, in case there was a problem with that, but I get absolutely nothing on screen. I have +v and ground at the circuits input pins and also at the connector for the sensor.
Please take pity on a poor fool who was just getting used to conventional electronics when I decided to have a stab at PICs, and though the circuits are simpler to build they seem even harder to fault find on! DOH!
Thanks for looking.............Al
