RE: HP97 The journey begins
Hi all,
Well, those few forward steps have been overtaken again by some backward ones. Even though the printer is working ok, there is a problem running the printer code with the rest of the tasks the PIC chip has to do. I tried running things in different forms, but there is no way to get it all to work properly with one processor chip. There are 5 major processing channels to deal with which is proving to be one too many. Although the chip can process everything in the required time, it cannot do so without upsetting the print output, the display and possibly with the card read write. These all operate in real time, so any interference to the data flow by trying to do too much will cause glitches. The actual HP PIK chip runs the printer as a separate process, so it looks like the CPU board is going to need a separate processor to manage the printer as well :-( cheers Tony |
