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 terminal virtual screen.
- output to SDL virtual screen.
- output to I2C graphics screen.
- output to SPI graphics screen.
Note: you may have to run make clean after you changed to a different output mode.
Output to terminal
To output to this virtual screen, supply TEST_OUTPUT=1 to the make command.
Output to SDL
To output to this virtual screen, supply TEST_OUTPUT=2 to the make command.
This is a native-only option and requires SDL (32-bits) to be installed.
Output to SPI
To output to screen, supply TEST_OUTPUT=3 to the make command.
TEST_SPI— The SPI device.TEST_PIN_CS— If applicable, the CS pin.TEST_PIN_DC— If applicable, the Data/Command pin.TEST_PIN_RESET— If applicable, the reset pin.TEST_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_OUTPUT=4 to the make command.
Furthermore, you can configure the following:
TEST_I2C— The I2C device.TEST_ADDR— The address to write commands to.TEST_PIN_RESET— If applicable, the reset pin.TEST_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'.
