Other Parts Discussed in Thread: DLPC2607
Hi,
I am using DLPDLC2000 for my project demo.
I am using MAC57D5xx as master and dlp as slave. Sending I2c commands from my master to dlp and observe nothing. I tried both slave address 0x36 and 0x1b as they are multiple sources mentioning different slave addresses. but neither of them helped me getting response from dlp. I2c test case i performed are as follows.
Case1 : Setting RGB LED Driver.
0x36/0x1b 0x16 0x00000007 (Enabling RGB LED driver)
Expectation: Expecting blank screen from projector as RED, GREEN, BLUE LED driver currents are set to min current 0x3fff and WPC function is disable by default i.e, 0% LED's ON .
Result: FAIL(observing the same DLP default screen )
Case2: Reading Pixel data format
0x36/0x1b 0x15 0x0D
Expectation: 0x37 0x02 (default pixel foramt is RGB888)
Result: FAIL(no data received)
I am only connecting DLP with %V power source and SCL SDA lines from my master. I am able to clear observe the data sent from my master using CRO. I am blae to see LED D2 flash and then turn off , LED D3 turn on continuously and DLP default image from projector.
When my master is waiting for acknowledgment from slave , dlp is not really acknowledging.
Let me know,
1. Whether my connections are enough for the above mentioned test cases.
2. i2c commands are proper for my test cases.
Thanks & Regards,
Renuka Reddy.
