Example Seeeduino (Arduino clone) code for the Crystalfontz CFAL12864D1-0154MY display. This is a yellow OLED with a 1.54" diagonal that can be interfaced with by SPI, I2C, and 8-bit Parallel.
The display and dev kit can be found here:
CFAL12864D1-0154MY - OLED display
CFAL12864D1-0154MY-E1-2 - OLED display + carrier board + Seeeduino pre-programmed with demo code
There are two carrier boards that can be purchased seperately if desired, the CFA10105 and the CFA10102. The CFA10105 is plug and play with this display and is the preferrable option. The CFA10102 is a generic board that will require the passive components to be soldered to it.
CFA10105 - plug and play adapter board
CFA10102 - generic OLED adapter board
Please note, the BS1 and BS2 jumpers should be unsoldered
