New Viscometer Board

Well, my design finally came to fruition from AP Circuits and I can say I’m quite pleased with the results. The overall appearance of it is really nice, for me at least.

Interestingly enough, I had some problems and made some mistakes. I ties the power regulator input into the motor – terminal… weird. Also, I didn’t tie AVdd high, or to anything.

Remember, programming a pic, remember these things

  • Use caps across power
  • tie ALL Vss and Vdd to their respective rails
  • tie AVss and Avdd to their respective rails

I kept ketting a “Error programming at address 0x000000” error and it turned out to be the Avdd was disconnected.
