1: I need a board to control 14 channels of LEDs. And the brightness of each channel need to be adjustable seprately. So I chose TLC5946, is it a good choise?
2: If use TLC5946, Can I use I2C or UART or other common interface to communicate with the serial control input interface(SCLK, SIN). If not, what should i use? an GPIO of MCU?
3: Is there any reference design include schematic and software(MCU+TLC5946)?
