EK-TM4C123GXL: About I2C write for ISET setup and some config. parameter by LED171596AWVM

Part Number: EK-TM4C123GXL


Hi everyone, 

I need to control some LEDs (duration 10-50ms; Frequency 10-50Hz; Current 10-600uA; ) by using LED171596AWVM with TM4C123GXL. I already maximized the maxBri and the MasterBri with 0x1ff. So, the PWM should be 100%. The current output should only rely on the current value itself. However, I have some issue regarding ISET setup and some config. parameter.

1) I know how to set them but I don't know how parameter of the LED Driver, PWM and Sloper config, is reasonable to my project? (as fig,1)?

2) I can see the log in EVM software and I can select them (e.g. 10mA, 12.5, ..., 60mA) (as fig.2). But I don't know how to I2C write this ISET to initial peak current with a program?

Thank you in advance!
