Dears:
Pls. help to give some advice to enhance the lightness.
From the below code and schematic, only under torch mode LM3644 can drive the LED lighting(HWEN and STROBE are high level and ignore the signal of TORCH/TX connecting with CPU) , however, the lightness is not enough.
lm3644_write_register(0x05, 0xbf);
lm3644_write_register(0x06, 0xbf);
lm3644_write_register(0x01, 0x2b);
Btw, from the datasheet I can see the Brightness level under Flash mode is higher than under Toch Mode.
And the time-out is only 400ms under Flash mode.
Can LM3644 drive the LED is always bright under Flash mode?
