Hello,
i hope you will understand my English because i’m from Germany.
I bought the K8048 and installed all components on the base plate, but two jumpers are left. What function these two jumpers have? Are they necessary for standard operating with this board or for special operations while programming a PIC? I can’t find their function in the manual.
I’m sure they’re described somewhere in the manual. Anyway, they are to select which programming socket the crystal will be connected to. There are 2 headers next to each of the 3 lower sockets, you should short out both headers (using the jumpers) of the socket you are using to program your PIC.
That is unless your PIC has an internal oscillator, such as the 16F819, or any of the 12F series.
I bought a K8048 experiment board and it works fine. I am trying to writer programs using the book “PIC in Practice” by DW Smith which I understand is quite widely used by PIC programmers. But when I use the code from the book it doesn’t work (although the demo code that came with the kit works absolutely fine), I think it’s the timer function in particular that doesn’t work although I also can’t light LED 5.
I realise that this isn’t a problem with the board but I wonder if you could help me anyway, or at least point out what the problem might be and where I should go to find a solution.
