Re: EB-006-00-8 Programmer

Didn't get a response for my post - Ended up getting a PICkit 3, saving the flowcode file an a hex format and dumping it into the PIC18f26k80 vis the required 5 pins on the chip. Now I don't have to remove the chip to program.

Re: PIC18f26k80 Analog

I made a few changes and empirically ended up with Fosc/4 and 6 cycles acquisition time. Certainly got my analog acting more realistic.
If you wouldn't mind detailing me about the values - Is it more beneficial to be slower?

Thanks much - I can take it from here. :D

Programming to chip EB-006-00-6

V7 Programming a (new) chip PIC18F2553 creates compiler error message indicating:

1.Board voltage too high
2.Board voltage too high
3.Flash memory not verified - may be due to code protect.

FINISHED

Chip is not programmed.

Flowcode 5 programs these just fine. Can you investigate?

Zero crossing detector hardware.

If you want to pick up the zero point of the AC mains, a novel method (see attachment) is to use an opto isolator with two emitters reverse connected in parallel. The only time a positive signal is available, is when both LED emitters are not conducting (mains is at zero). RB0 interrupt will be evok...

Re: Zero crossing detector hardware.

Not sure if my particular code will add anything so I have increased the resolution for a partial look at the development of "states" in the interrupt routine which can be used to determine what to do in the main program.

Re: Rotary encoder: 4 counts per click?

The reason it is called a "quad" encoder, is because it counts the state change of each edge. Since there are 4 edges per cycle, that would equate to 4 counts per "count". Your encoder is probably mechanically indented creating the sine and cosine signal. For a no indented encode...

Icon Colors

FC7 copy and paste does not maintain the modified color pallet. Might be worthwhile changing for the next rev level:

Re: Pic18f2553 Port C problems

Never mind - Those port C pins are input only, although FC7 allows me to select those pins as outputs even though they are not available as outputs.

Re: PIC18f2553 RA6

I renamed the old file, and copied your file into the directory. Relaunched FC7 and now I get to select A6 as an output.

Thanks for this.

Re: Interrupt difficulies pic18f2553

Oops - Actually, I turned off the computer and restarted to resolve the issue.
