Create sequence pattern in C++ API

Other Parts Discussed in Thread: DLPC350

I would like to create pattern sequence using C++ API, but i have problem with validation sequence. Validation sequence pattern return status 128, I can't read in instruction, what that error means. I based on this: https://pastebin.com/JfnFjSiG . I have flashed all pattern, i can control this projector via DLPLCR4500GUI-3.1.0 and work fine. 

What this error code means ? Is this problem related to this error?


Thanks in advance.

    Hello Łukasz,

    You can take a look at the DLPC350 programmer's guide to view the error status bits. It appears a return code of 128 for I2C command 0x7D indicates "DLPC350 is busy validating. Once the bit is clear, interpret the rest of the bits". You should keep polling until bit 7 is cleared and you receive back a 0x0.

    Thanks,
