Other Parts Discussed in Thread: DLPA3000
Hello,
I have a DLPC3433, DLPA3000 and a light engine that supports 1280x720 resolution.
I am trying to get it to work with DSI signal from an R16. Along the way, I am trying to set the display size.
But no matter what the read register (0x13) always appears to return all zeros? Why is that?
Here is the bash:
[root@alarm ~]# i2cset -y ${BUS_NUM} ${DLP_ADDR} 0x12 0x00 0x06 0x20 0x03 i
[root@alarm ~]# i2ctransfer -y 1 w1@0x1b 0x13 r4
0x00 0x00 0x00 0x00
[root@alarm ~]# i2cset -y ${BUS_NUM} ${DLP_ADDR} 0x12 0x00 0x05 0x02 0xd0 i
[root@alarm ~]# i2ctransfer -y 1 w1@0x1b 0x13 r4
0x00 0x00 0x00 0x00
[root@alarm ~]# i2cset -y ${BUS_NUM} ${DLP_ADDR} 0x12 0x00 0x01 0x00 0x01 i
[root@alarm ~]# i2ctransfer -y 1 w1@0x1b 0x13 r4
0x00 0x00 0x00 0x00
