3.5 inch touch screen. Superseeded by Hyperpixel 4.0
Reasonable quality, touch is, though it i capacitive, not too easy to use. Resistive screens an be handled with pens, not this one.
With current Buster not a perfect pair.
Two experiments:
Raspberry Pi 2 B V1.2 success
1 imaged a SD with current Buster (feb 2020)
2 booted on a Pi 4 1 GB
3 did the usual raspi-config things and update/upgrade
4 checked out the system, works as expected
5 curl https://get.pimoroni.com/hyperpixel | bash
6. rebooted , installed Hyperpixel
Result is a working display, HDMI whosw rainbow screen, touch is wrong, cursor moves opposite directions, axes mixed up.
So not too bad, but touch not configured correctly.
Fixed with, in a console window, the command
$ hyperpixel-rotate normal
which changed the orientation of the screen to what is aleady was, and changed the touch matrix to a working touch.
So far so good.
Raspberry Pi 4 1 GB failure
To check out the Pi4, current Buster (feb 2020) and Hyperpixel 3.5 I did the following:
1 imaged a SD with current Buster (feb 2020)
2 booted on a Pi 4 1 GB
3 did the usual raspi-config things and update/upgrade
4 checked out the system, works as expected
5 curl https://get.pimoroni.com/hyperpixel | bash
6. rebooted , installed Hyperpixel
Result is not a working Hyperpixel display, but reverse image on HDMI, Hyperpixel dead.
Which is the same effect as booting from the working Raspberry Pi 2 SD.
Maybe the curl https://get.pimoroni.com/hyperpixel | bash gets the old hyperpixel install and not the Pi 4 version? Looks like it.
So back to
1 imaged a SD with current Buster (feb 2020)
2 booted on a Pi 4 1 GB
3 did the usual raspi-config things and update/upgrade
4 checked out the system, works as expected
5 downloaded the Hyperpixel Pi 4 git repository
6. rebooted , installed Hyperpixel with ./setup.h
Result is Hyperpixel noise banner, HDMI shows normal screen
So install fails with the curl or setup, and instructions clearly wrong.Issue opened at Pimoroni.
