Other Parts Discussed in Thread: MSP-EXP432E401Y, LP5569
Hi team,
My customer is evaluating this device, and EVM needs MSP-EXP432P401R Launchpad, but it is not available now, can we use MSP-EXP432E401Y instead?
Best,
Zeming

Hi Zeming,
Sorry for that, but MSP-EXP432E401Y is not useful to drive the EVM.
Considering this situation, I can give them a brief guidance to light up EVM.
LP5569 is not a complex device, so it only needs a few I2C command to use.
Please let me know if the guidance is acceptable for customer.
Thanks!

Hi Zeming,
If they can use their own MCU to control it, please try the following register configuration:
Reg [0x00] = 0x40 // CONFIG
Reg [0x22] = 0xAF // LED0 Current Default @ 17.5mA
Reg [0x2F] = 0x59 // Internal 32kHz enabled
Reg [0x33] = 0x02 // Headroom Default @ 250mV
Reg [0x3C] = 0x80
Reg [0x3D] = 0x02
Reg [0x80] = 0x04 // PWM CONFIG
Reg [0x16] = 0xFF // LED0 100% duty cycle
Thanks!
