Other Parts Discussed in Thread: DLPC230S-Q1, DLPC230-Q1
Hi, I'm creating a Host controller to control the DLP (I2C) and read status from the DLP (SPI). I generally have the control portion working now but getting status doesn't seem to be.
This is the waveform that I'm currently sending to the DLP through SPI:
First, I send a Prefetch command (0x01) with diagnostic op-code (0xF0) starting at byte 0 and only getting 2 bytes back. Also, I've set the interface to checksum.
Then, I send a Read active command (0x02) and 2 dummy bytes after the checksum.
However, throughout these transactions, I don't see any activity on the MISO data line.
Does the waveform look off or incorrect? Am I sending the correct data to get the diagnostic data?
