RZA1 LVDS
Supported Devices
- RZA1H
- RZA1M
Supported RZA1 Boards
- RZA1H Display-it Kit ( RSK )
- RZA1H MBED GR-Peach
RZA1H Display-it Kit ( RSK ) Modifications
For the RZ/A1 RSK Board, some resistor changes are needed in order to route all the LVDS signals to the CN17 connector.
On the RSK board, the defaults 0-Ohm resistor populations for P5_5 is for RAW NAND flash, and P5_7 is for SPDIF_OUT
(S/PDIF digital audio interface).
RZA1 LVDS Demo Project
While the LVDS is supported in all the RZA1 Drivers the parallel TFT is used for demos. A simple LVDS and parallel demos is available here. The demos includes the full FreeRTOS SDK for the RZA1H and RZA1M. The demo shows a color black ground that switches between 8 colors. This demo is recommended to verify that the hardware is working, the the VDC Display driver graphics layer is configured correctly, and the display driver control signals (TCON) are correct. Below shows where the configurations are located in the project.
