OLED & Controller
The integrated built-in controller used by this OLED is SSD1309, which has 128 × 64 bits SRAM, supports up to 128 × 64 pixel screen, supports SPI/I2C/ 6800 parallel port/8080 parallel port, 256-level brightness settings, this screen is 128 × 64 pixels, so the internal SRAM is not fully used.
This module adopts four-wire SPI and IIC interfaces, with good compatibility and high transmission speed.
SPI Communication Protocol
The 4-wire serial interface consists of SCLK, SDIN, D/c#, and CS#. In 4-wire SPI mode, D0 is SCLK and D1 is SDIN. For unused data pins, D2 should be kept open. From pins D3 to D7, "E" and "R/W# (WR#)#" can be connected to an external ground.
SDIN is shifted into an 8-bit shift register in the order D7, D6, ... on each rising edge of SCLK. D0. D/C# samples every 8 clocks and the data bytes in the shift register are written to the RAM (GDDRAM) or command register where the graphics display data is within the same clock.
