A project log for PICTIL

Remake of the TIL311 hex LED display with recent technology.

I did upload a new software version to the bitbucket repository. Now the input latch is supported. And I fixed also the wrong order of the input Pins, which I did noticed when comparing it directly to an original TIL311.

The latch pin is slower than at the original TIL311. This can be already noticed when controlling this pin manual by plug/unplug the wire on a breadboard. One thing I will try to fix that is a external interrupt triggered by a negative edge on the latch pin (RA3 on the PIC).

nice idea :-) setup & hold will be tighter with an IRQ, since you won't have to poll. It will only depend on the refresh rate.
