Touchscreen

The new touchscreen came today! This screen was a lot easier to configure and was almost plug and play. The previous Adafruit screen used the GPIO exclusively to show the display and send touchscreen inputs. This screen (I believe to be from 'Waveshare') displays using the HDMI output, and send touch inputs via USB, saving the GPIO for my audio card. The power is also external which means I can save power from the RPi.

Luckily my power pack has a second power output! All the hardware in these pictures is going inside the guitar.

Reference pictures for size, course the border of the screen will be covered.

Hideous overscan

Little editing of the /boot/config.txt file and hey presto!

Tutorial with this exact model of touchscreen was from:
