      Playing with the 3 POV messages as described in video on Update #6 A Bit of a Software Update (Nov 3)

      Using what I'm calling version 2 code (DigiRule 18F43K20 Button Bounce Fix by Gav.hex), I can use the Logic B button to cycle through the 3 different messages rather than the counter up/down buttons as shown in the video. The .bas file also seems to say to use the Logic B button.

      But, when I load in code version 3 (DigiRule 18F43K20 Modified 06 Dec 2015.HEX), I can no longer use any button to get to the other two messages.

      Just for the heck of it, I cranked the oscillator down (rather than re-compiling with Swordfish, changed the value being loaded to OSCCON at location 0F5A using the standalone PICKIT2 application; i.e. changed 0E60 6ED3 for 8 MHz to 0E50 (4 MHz), 0E40 (2 MHz) and so on.

      I was thinking that maybe with the debounce variable being so high, perhaps a slower clock speed would allow the code to see that Logic B button push and change the message. But no cigar.

      It was interesting, however, to see the reverse of button bounce where stuff advances too much per button push. Instead, with say a 1 MHz clock, it took about three button pushes to get any change.

      I live in France, in Grenoble, and I've received my DigiRule two days ago ! (On Thursday 10)
      It's absolutely awesome, I'm going to buy a Pickit to fix the button problem, but I'd love to have a guide about how the code works to be able to change / add functionalities to my DigiRule !

      My own personalized Rule, it would be completely awesome !!!

      I received my 5-pack of digirules this past Wednesday, December 9th. I'm in Toronto, ON, Canada.

      Hello! The digital is a fine thing that would pivot to the have been better if you had your own text can be entered, and a guide to reprogram would be awesome. Likewise, the battery is missing number, the time is CR1220 inside, but I do not know if it's right! Fine III. Advent. Martin

      I love my DigiRule and I don't even have a battery in it :) It's just awesome to look at and feels really sturdy.

      The print on the back is fine in my opinion.

      I really regret not getting a few more as presents for my friends and family this christmas

      I'm in Vienna, Austria, still waiting for a sign of my DigiRule. I'm confident that it will come though. International shipments tend to take some time, even in the capital. I'll also pick up a PickIt and wait for your tutorial (as I am not well versed in manipulating firmware).
