Project details
This controller had a AC-DC converter whose output was modulated by a microcontroller
to control speed and comutation noise. It used a 87C752 processor for the
final controller. During development I used a 87C552 and added code to
allow it communicate with a PC. The PC was then set up to download modulation
waveforms to the controller to allow real time noise testing. I wrote a
LabView program on the PC to allow graphical adjustment of the waveform
and send it to the controller. Functions where added to the LabView program
to generate custom sine waveforms speeding adjustments.
