The default value of engine 2 start address is 0x10 , if you will map the leds you want to use on the start of engine 2, you need to check mux_map_start address.
Part Number: LP55231 Hi all,
The datasheet for LP55231 indicates there is over-current and short-circuit protection with LED error detection, but does not elaborate on whether keeping those outputs floating would be OK. I assume grounding these unused…
Part Number: SIMPLELINK-CC13X2-26X2-SDK Other Parts Discussed in Thread: LP55231 , CC2640 , LP5523 , TIDA-00757 Hi Ti Expert team,
I am working with LP55231 led-driver. Driver ic has 3 engines. but the engine is not triggered with CC1312/CC1352 MCU I can…
Part Number: LP55231
Hello,
I am considering the configuration in the figure below as a way to control many LEDs. Connect the Dx pin to the gate of the FET and connect the LED in series to the drain of the FET. Is such a configuration possible? Is it possible…
Part Number: LAUNCHXL-CC1312R1 Other Parts Discussed in Thread: LP55231 , CC1312R Hi
Do you have library code .c, .h for your RGB driver LP55231.

Part Number: LP55231 Hello,
Not all but some LP55231 units show behavior that unintentionally turns off outputs of D1 to D6 after the following procedure. I suspect it has something to do with its charge pump function because the behavior won't appear…
Hi Lumina,
Sorry for the late response. Is the low-level voltage reduced to <0.5V now? I have checked the Linux driver code and corresponding schematic; no obvious issue is detected from inspection.
Best Regards,

Part Number: LP55231 Hello,
I am using the LP55231 to drive 9 white LEDs and have a question that I cannot seem to find the answer to in the data sheet.
My question is about if you can use both the master fader registers to control the LEDs as well as…
Part Number: LP55231 I am trying to figure out if 121K ohm resistors are a good choice for pulling up the TRIG, INT, and EN pins on the LP55231. I know section 8.1 of the datasheet recommends using from 120k to 180k "for two devices". What is a good choice…
