gj22-18 Two motors connected to D flip-flop 10 Mon 10-22 XC Directions.
gj24-15 Tone translator input processor 10 Wed 10-24 XC Get handout sheet.
gj24-19 Toggle flip-flop connected to real square wave generator 10 Wed 10-24 XC
  1. Load the toggle flip-flop program (gj17-17) into a PIC board.
  2. Get the PIC-board schematic and assembly drawing.
  3. Run a one-to-one ribbon cable from J1 on the PIC board to one of the white breadboards.
  4. For the remaining steps, make your connections on the white breadboard.
  5. Get a function generator, and be sure it's turned off.
  6. Connect the ground of the function generator to ground on the PIC board.
  7. Connect the TTL output of the function generator to PIC-board input switch 0 (RA0).
  8. Also, connect channel 1 on a scope to input switch 0.
  9. Connect scope channel 2 to output line 0 (RB0).
  10. Turn on the function generator, and set it to square waves at 1 kHz.
  11. Channel 2 should have half the frequency of channel 1. The jitter in the waveform on channel 2 is normal, and is a result of the program sometimes catching the square wave right when it changes and sometimes catching it a little after.
