By scaling the +9.4 Volt to 14.5 Volt battery voltage with a Zener Diode and a 10K resister you can display the Battery voltage with two decimal points resolution on the Two Line LCD of a EasyPic V7 Development board using the RA1 AtoD input of a PIC16F76 Microcontroller.

I have only had the EasyPic V7 for about a week now and this is my first real program using MBasic. I haven't done any programming in about 10 years and then it was mostly assembly  using 8048 and Z80 MP's so bear with me. Any hints or corrections will add to my learning curve so don't hesitate to comment.

 

I can say it sure would have been nice to have tools like this setup back in the day.

 

Thank You

Dick

I found several things I did wrong due to my learning curve. The display has been rearranged to avoid the flashing and I was able to remove the delay at the end. full explanation is in the comments.

Thanks For Looking

Camper Light Control Project Update

This is the mid point of this project. The Light Control is working with Blue Tooth Coms between the head end and the light controller. The VGLCD code is working the touch panel to turn on and off lights. I will be adding Voice Control using the Speak-Up and Smart_MP3 modules in the near future. Enjoy New Version, more functionally.
