Revision as of 20:21, 30 March 2017

Manga Screen rev B is a 5.9" LCD screen with a capacitive touch panel and an HDMI input.

If you have a Beaglebone black, a Raspberry Pi or (eventually) an Arduino Tre or any other embedded or personal computer with a DVI or HDMI output, you can attach a Manga Screen to it and it will work like a normal screen.

The resolution is high for such a small screen with 1080x1920 (Full HD) and the capacitive touch screen driver used is the fabulous Synaptics S3202.

Here are some tech specs:

Here is a picture of a prototype in action:

Where to buy

Rev B is still in development, but there will be a Kickstarter campaign late Q1 2017.

Cables

HDMI

The HDMI connector on the screen is a type A (regular) https://en.wikipedia.org/wiki/HDMI#Connectors

USB

The USB connector on the screen is of type micro. It can be purchased in just about every Cheap Charley like store.

Getting started

Raspberry Pi

Manga Screen Rev B has been tested on Raspberry pi 1, 2 and 3.

Screen rotation

If you have a Raspberry Pi, you will need to override the settings manually to get the right rotation and resolution. Look at the config page for Raspberry Pi, the section called "custom mode" for HDMI: https://www.raspberrypi.org/documentation/configuration/config-txt.md

Edit the config file:

sudo nano /boot/config.txt

Add this to the end of it:

hdmi_cvt=1080 1920 30 5 0 0 0
hdmi_group=2
hdmi_mode=87

max_framebuffer_width=1920
max_framebuffer_height=1920

display_rotate=1

Touch panel rotation

BeagleBone Black

Works with resolution 1088 x 1920. Note that the x-resolution needs to be a multiple of 16. The remaining pixels will disappear into the vertical back porch.

Windows

Omxplayer

Linux users

Typically, the touch input is mapped to the main screen. To map the touch panel to the screen in X, use following command: ``` xinput map-to-output <device_nr> <output> ```

Adjusting things

When plugged in the screen should enumerate as a mixed device, both a touch device and a serial device. The touch device will provide the touch screen data and the serial device can be used for controlling stuff on the screen.
