# U8g2 Package Test
|
||||
|
||||
## About
|
||||
This is a test application for the U8g2 package. This package is a graphical display library, including display drivers.
|
||||
|
||||
## Usage
|
||||
This test application will initialize the U8g2 to output on one of the following:
|
||||
|
||||
* output to stdout virtual screen.
|
||||
* output to SDL virtual screen.
|
||||
* output to I2C graphics screen.
|
||||
* output to SPI graphics screen.
|
||||
|
||||
### Output to stdout
|
||||
To output to this virtual screen, supply `TEST_U8G2_OUTPUT=1` to the `make` command.
|
||||
|
||||
### Output to SDL
|
||||
To output to this virtual screen, supply `TEST_U8G2_OUTPUT=2` to the `make` command.
|
||||
|
||||
This is a native-only option.
|
||||
|
||||
### Output to SPI
|
||||
To output to screen, supply `TEST_U8G2_OUTPUT=3` to the `make` command.
|
||||
|
||||
* `TEST_U8G2_SPI` — The SPI device.
|
||||
* `TEST_U8G2_PIN_CS` — If applicable, the CS pin.
|
||||
* `TEST_U8G2_PIN_DC` — If applicable, the Command/Data pin.
|
||||
* `TEST_U8G2_PIN_RESET` — If applicable, the reset pin.
|
||||
* `TEST_U8G2_DISPLAY` — The used display driver (see https://github.com/olikraus/u8g2/wiki/u8g2setupc). Make sure you select a SPI compatible display.
|
||||
|
||||
### Output to I2C
|
||||
To output to screen, supply `TEST_U8G2_OUTPUT=4` to the `make` command.
|
||||
|
||||
Furthermore, you can configure the following:
|
||||
|
||||
* `TEST_U8G2_I2C` — The I2C device.
|
||||
* `TEST_U8G2_ADDR` — The address to write commands to.
|
||||
* `TEST_U8G2_PIN_RESET` — If applicable, the reset pin.
|
||||
* `TEST_U8G2_DISPLAY` — The used display driver (see https://github.com/olikraus/u8g2/wiki/u8g2setupc). Make sure you select an I2C compatible display.
|
||||
|
||||
## Expected result
|
||||
The output of this test depends on the output mode and used hardware. If it works, the application cycles through three screens with the text: 'This is RIOT-OS'.
