DSITx

FPGA implementation of DSITx (single lane) used in conjunction with ipod nano 7th gen display

This is a generic (behavioral) code for MIPI DSI Tx. Can drive the Ipod Nano 7th gen LCD display without a problem. Developed on Lattice MachXO2 dev board (the one with 7000HE).

Operation

1. FPGA reads bytes from on-board FTDI chip (one port used as USART, other one is for programming the FPGA - obviously)
2. Bytes are pushed into SLIP decoder (slip is used to turn raw UART byte stream to frames with start/end delimiters)
3. Decoded bytes and frame signal are used to drive the DPHY
4. DPHY does the Low-power <-> High Speed mode transitions and pushes all the data on the data/clock lane
