Christmas PIC16F1938 not behaving

Post by JLeith »

Hi All
I have a simple design for a future DFPlayer that is still in route.

I have a design that works in Flowcode 6 but when I load the PIC the LCD will not display the text.

I though I had a bad chip so I ordered new and the same results.
Here is what I have done.
1. Wired per my design on a bread board.
2. Tested the 16x2 LCD in another design and it works.
3. I have a little more work in sending the port codes to the DFplayer.
On a side note does anyone know on the DFplayer do I need to activate the "Play mode before I select the Segment to play?

Puzzled.

I have attached the LCD wiring and the Flowcode.
Must be missing something that I hope others can see.

Thank you
John

I found my error
As soon as I posted the information the light went on.
No Power outage just a memory glitch

I forgot to check the Oscillator settings.

Sorry to post without double checking my options.
