Well, For the last week or so I’ve been developing a new viscometer board. Sloppy as it is, it’s a jump ahead from the last board in terms of overall inputs allowed. I used the 68PLCC package PIC18F6680 in this one because it had a sufficient number of IO and because it looks cool in it’s socket. 🙂
Anyways, this one has the following features:
- Several analog channels for temperature measurement.
- Several analog channels for use in a torque sensor set-up.
- Some analog channels.
- built in RS-232 Output.
- built in RS-485 Output.
- Provisions for PICKit2 hookup.
- TVS’s on all input lines
- Separate PIC12F683 for PWM output
- Debug Serial Output.
All in all, it’s gone smoothly, I’ve double checked a number of the traces, let’s hope all of them are well when they come back from AP Circuits later on. 🙂
