ARM7 based OLED analog clock face
This is great project demonstrating an organic LED display interface. ARM7 (AT91SAM7S64) microcontroller displays and analog clock face on OLED screen which has 18 bit color range and is low power. Project uses DS3234S RTC IC that is interfaced to ARM7 microcontroller via SPI port. Another interesting feature is that clock uses a light sensor TSL256 which enables to adjust displays brightness according to ambient light level. So in dark environment clock is dimmed while in bright room brightness is high. OLED allows 16 brightness levels.
