==Overview==
The Q100 is an expansion board similar to [[X1000]]. It has the function of PCIE to NVME ssd and also has an attached a 1.3" 240x240 Color TFT(ST7789 chipset), The TFT can display system and SSD status information, making it ideal for use as an additional display for NAS or media systems.
{{PCIe to NVME Sets}}
==Features==
* NVMe Base PCB with M.2 Slot (M-Key NVMe SSD with 2242 sizes)
* With ACT LED Indicator(Flashing: Reading /Writing)
* With 40pin GPIO Header，it can supply power from GPIO,avoiding the problem of insuggicient power supply for ultra-large capactiy SSDs
* 1.3" 240x240 Color TFT (ST7789 chipset),The TFT can display system and SSD status information, making it ideal for use as an additional display for NAS or media systems.
* 'PCIe Pipe' Flat Flex Shielded Cable(50mm length FFC Shielded Cable),shielded cables can provide better PCIE performance, effectively solve the interference problem between PCIE and WIFI, and provide a more stable data link for SSDs.

==LCD and the controller==
The ST7789VW is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 240 source line and 320 gate line driving circuits. The resolution of this LCD is 240 (H) RGB x 240(V), it supports horizontal mode and vertical mode, and it doesn't use all the RAM of the controller.
This LCD accepts 8-bits/9-bits/16-bits/18-bits parallel interface, that are RGB444, RGB565, RGB666. The color format used in demo codes is RGB565.
This LCD use a 4-line SPI interface for reducing GPIO and fast speed.LCD
==LCD Working Protocol==
[[File:Q100-lcd-work-protocol.png]]
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.
RESX Is the reset pin, it should be low when powering the module and be higher at other times;
CSX is slave chip select, when CS is low, the chip is enabled.
D/CX is data/command control pin, when DC = 0, write command, when DC = 1, write data
SDA is the data pin for transmitting RGB data, it works as the MOSI pin of SPI interface;
SCL worka s the SCLK pins of SPI interface. SPI communication has data transfer timing, which is combined by CPHA and CPOL. 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. CPHA determines whether data is collected at the first clock edge or at the second clock edge of serial synchronous clock; when CPHL =Packing List0, data is collected at the first clock edge. There are 4 SPI communication modes. SPI0 is commonly used, in which CPHL =0, CPOL =0.
