We had a problem with the torch mode not turning on without repeating the command. When identifying the reason I found the problem also exists when switching from torch mode to IR mode with strobe. I have verified that there was no error condition.
The design is such that register 0x01 should contain 0x02 for torch mode or 0x05 for IR strobe mode.
Included are logic analyser captures to show register 0x01 not changing correctly:
I write 0x02 to register 0x01 to turn on torch mode, reading the register shows it now contains 0x00. The LED also doesn't turn on.
I write 0x02 to register 0x01 again. This time it changes to 0x02 and the LED turns on.
I write 0x05 to register 0x01 but when read it shows it contains 0x04.
I write 0x05 to register 0x01 again and this time it reads correctly.
