It is remarkable how much I forgot about C programming.  It is definitely a perishable skill.  Nevertheless, I’ve muddled through.  I won’t bore you with all the iterations it took me to get to this point, and I’m certainly not done, but I do finally have the graphics display at least displaying frequency.

Here is what it looks like in the front panel of the radio, although still wired in all over my bench:

The display with full voltage to the LED backlight is quite bright, very easily readable in bright conditions.  I plan on having it run at very very reduced brightness except when the LED backlight in the radio is called upon to be on in which case I’ll go to full brightness.

Next is getting the status info onto the lower part of the display.  I’ll have to experiment with the font to see what looks best.  I will have a line like:

Chan 5   Power M

Then in the upper right will be the left or right arrows for tuning, the lower right will be the battery/transmit power bar indicator,  and after the power indication I was thinking of a band segment indicator (X or G) as a reminder just for fun.  I’ll also get the other misc things in there somewhere like the RX indicator, but I’ll have to play to optimize the visual look of this.

For messages, they’ll use good fonts instead of partial 7 segment and for “pass” I’ll show BITE PASS in the freq area.  So, a lot more work, but I’m getting there and it looks pretty decent!
