Pushing Past Obstacles

A project log for Universal Glucometer

Did your test strips just get more expensive? Has the drug store run out of strips for YOUR meter? Like to be able to use any test strip?

The LCD in Microchips Reference Design has a lead spacing I haven't seen before. So... I I used some strip board to make an adapter so it can fit into a standard 0.1”pitch breadboard. While adjusting the angle for better viewing I cracked the glass so I placed a new order for:

I've finally gotten the reference/base coder from Microchip to compile without any errors, and finished bread boarding the reference design (well.. mostly, see below).

While finishing wiring the bread board I found that I have the incorrect LCD display. I ordered, and have, the C0216CiZ instead of the C0216CZ LCD display (it seems that now few suppliers carry the CZ and instead only have the CiZ display – both are 16 x 2 LCD displays but they are much different in pin out and use different protocols). There seems to be some code libraries for more standard 16 x 2 LCD displays, so I will attempt to implement them instead – since it will be easier for other people to replicate my final design.

Having never worked with PIC's before (only Arduino's and AVR's), editing and adding to code is challenging so far – but I am working at it every day and making steady progress.
