5 | This is a set of example captures of the signals on a controller for the | |
6 | 5050RGBSet LED strip. | |
7 | ||
8 | The signals were grabbed on a 14-pin SOIC chip (no markings). | |
9 | The red/blue/green pins on the chip control the (R/G/B) LED color, the | |
10 | SDA/SCL pins are connected to an Atmel AT24C02N EEPROM, and the IR pin is | |
11 | directly connected to the wires leading to the IR remote receiver. | |
