# Raspberry-mgrx
2D graphics library for FrameBuffer
MGRX is a 2D graphics library derived from the GRX library.
GRX was originaly written by Csaba Biegl.
MGRX was originaly written by M.Alvarez.
This was transplanted for RaspberryPi & OrangePi.
I tested by the following environment.
Raspberry Pi + ILI9341 SPI TFT.
OrangePi PC + ILI9325 Parallel TFT.

# Install
```
sudo apt-get install libjpeg-dev libpng-dev
git clone https://github.com/nopnop2002/Raspberry-mgrx
cd Raspberry-mgrx
make -f makefile.lnx libs
sudo make -f makefile.lnx install
make -f makefile.lnx test
```

# Demonstration
```
$ export MGRXDRV="linuxfb gw gh nc "
is width of FrameBuffer.
is height of FrameBuffer.
Values for nc can be 2, 16, 256, 64K or 16M.
You can get these by the following command.
$ fbset -i -fb
$ export FRAMEBUFFER=
```
If you have 320x240 TFT module like ILI9341, it'll be as follows.
- for Raspberry Pi
```
$ export MGRXDRV="linuxfb gw 320 gh 240 nc 64k"
$ export FRAMEBUFFER=/dev/fb1
$ cd $HOME/mgrx_rpi/test
$ ./demomgrx
```
- for Orange Pi PC
```
$ export MGRXDRV="linuxfb gw 320 gh 240 nc 64k"
$ export FRAMEBUFFER=/dev/fb8
$ cd $HOME/mgrx_rpi/test
$ ./demomgrx
```

# Operation
When the item is chosen by an arrow key and ENTER is pushed, demonstration starts.
demomgrx is a simple launcher program.
It's possible to start each demonstration program directly by a command line.
