|
|
Device pinouts are comments in ssd1306_setup.py.
|
|
All tests take two boolean args:
|
|
use_spi = False. Set True for SPI connected device
|
|
soft=True set False to use hardware I2C/SPI. Hardware I2C option currently fails with official SSD1306 driver.
|
|
|
|
Available tests:
|
|
fields() Label test with dynamic data.
|
|
multi_fields() More Labels.
|
|
meter() Demo of Meter object.
