As advised in the related question, I made use of the bit 3 in the LED Enable Outputs Command (0x1A07) to resolve the problem with the LEDs being on when DMD Idle Mode is enabled. In fact, the issue with the DMD Idle mode was resolved, but a new problem appeared.
I run a small test:
1. On power up, the default pattern is displayed in the pre-stored pattern mode. The system status is as follows:
2. Then I stop pattern sequence. As expected, the pattern is no longer displayed. I only see the 'dark' lite (LEDs are ON, Sequencer is stopped). The system status is as follows:
3. Then I send the command LED Enable Outputs Command (0x1A07) with the data byte '00001000' (disable LED outputs, let the Sequencer control the the LED outputs). As expected, no dark light is displayed, since the LEDs got OFF. The system status:
4. Then I start the sequencer, expecting that the LED outputs to be ON and the default pattern to be on. However, even dark light is not present (the LEDs are still OFF, even though the sequencer is running). Here is the status:
The latter was a kind of unexpected behavior. Could you please comment on it.
Best,
Roman
