In our product we use DLP chipset to drive a DMD.
For testing the board used to drive the DMD , we use JTAG.
So, via JTAG we can control the DLPC and DLPR chips with one exception , the DLPA chip has no JTAG access.
What options do we have for testing the DLPA output lines?
We can use SPI communication , however I wan't able to locate the protocol commands.
We need only basic controlling ability, on/off is good enough.
Thank you in advance,
