Using the Waveshare 3.2 inch LCD

Post by G4FRE » Sat Jun 03, 2017 9:20 pm

By a clerical error I ended up ordering a 3.2" Waveshare LCD rather than the 3.5" Waveshare LCD. Not surprisingly when I booted the RPI I got a complete white screen and nothing useful.

Not wanting to waste the display, and inspired by http://www.batc.org.uk/forum/viewtopic. ... 905#p12252 I did the following:-

From "LCD-show-160811.tar.gz" on the install disk, I copied waveshare32b-overlay.dtb to /boot/overlays/waveshare32b.dtbo

changed "dtoverlay=waveshare35a" to "dtoverlay=waveshare32b in /boot/config.txt

I am documenting it here in case anyone else makes the same mistake!
