The 'hyperpixel-4'
(https://shop.pimoroni.com/products/hyperpixel-4?variant=12569485443155)
is a nice little display with good response and capacitive touch. It
does have some pros/cons that I'll list.
Pros:
- No wiring, all connections are made through the 40pin RPI header
- Fast Display, with Goodix based capacitive touch.
- All drivers are currently included in pCP
- This is an 800x480 display, so all of the jivelite skins that work
with the RPi 7" display work great.
Cons:
- This literally uses most of the GPIO header for the graphic
connection. The connection is direct to the rpi GPU. It runs the
GPIO in dpi mode. The only Free GPIO are 18 and 26
- This means you cannot use a i2S Hat board for sound, but Rpi Onboard
sound or USB based sound works just fine.
I have forked pimoroni's github 'Here'
(https://github.com/piCorePlayer/hyperpixel4). Which I will be updating
the sources to work properly with pCP and the libts that we use for
jivelite.
Installation will involve
- Commands added to the boot config.txt
- Adding a custom dtoverlay for the display
- Using a custom init program - based on the python script they
supply. (I didn't want full python to be a dependancy)
- Using ts-calibrate to calibrate the touchscreen
- Using a custom jivelite startup script. Similar to what is done for
the waveshare devices.
- Using the new lcd-brightness.sh script interface for pwm based
backlight control from within jivelite.
Well that's all the time I have for now, I'll be updating this post with
Actual details when I get more time.
