Hi
I used the LP5562 for RGBW LED driver. I can control it by I2C PWM mode. But I cannot load the pattern to the SRAM.
I read back the SRAM. It's all "0x00", don't know why., I have set the OP_mode to load program as datasheet described.
I have followed the example of datasheet to load pattern, but after I read the SRAM from 0x10~0x19, it's all zero and the enable register for engine1~3 are all "00b" (hold) state even I change it to "10b".
Could someone help me to figure out what's the cause for it? Thanks a lot.
BR, Jerry
