SPI TFT and Quad SPI TFT (Serial Peripheral Interface) is a synchronous serial data transfer protocol named by Motorola, . Here two or more serial devices are connected to each other in full-duplex mode. The devices connected to each other are either Master or Slave. In a SPI link there could as many Masters and Slaves as required, but it’s very rare to find more than one Master in a SPI link.
The Master device is the one which initiates the connection and controls it. Once the connection is initiated, then the Master and one or more Slave(s) can transmit and/or receive data. As mentioned earlier, this is a full-duplex connection, which means that Master can send data to Slave(s) and the Slave(s) can also send the data to the Master at the same time.
The Matrix Orbital EVE2 & EVE3 SPI TFT utilizes the FTDI FT812, FT813 or BT815, BT816 EVE (Embedded Video Engine) to create fast and economical HMI systems. With built in graphics operations, sound synthesizer, digital filter and support for multiple widgets you can create your own stunning screens and interfaces with the EVE Screen Designer software.
