==Working Protocol==
[[file:0.96inch_lcd_module_spi.png|900px]]<br />
Note: Different from the traditional SPI protocol, the data line from the slave to the master is hidden since the device only has display requirement.<br />
RESX Is the reset pin, it should be low when powering the module and be higher at other times;;<br />
CSX is slave chip select, when CS is low, the chip is enabled.<br />
D/CX is data/command control pin, when DC = 0, write command, when DC = 1, write data<br />
SDA is the data pin for transmitting RGB data, it works as the MOSI pin of SPI interface;<br />
SCL worka s the SCLK pins of SPI interface.<br />
SPI communication has data transfer timing, which is combined by CPHA and CPOL.<br />
CPOL determines the level of the serial synchronous clock at idle state. When CPOL = 0, the level is Low. However, CPOL has little effect to the transmission.<br />
CPHA determines whether data is collected at the first clock edge or at the second clock edge of serial synchronous clock; when CPHL = 0, data is collected at the first clock edge.<br />
There are 4 SPI communication modes. SPI0 is commonly used, in which CPHL = 0, CPOL = 0.<br />
