nxp_ip 3:40f83904f0a8 20 *
nxp_ip 3:40f83904f0a8 21 * "LedPwmOut" class works like "PwmOut" class of mbed-SDK.
nxp_ip 3:40f83904f0a8 22 * This class provides API on device's pin level with abstracting the LED controller.

nxp_ip 3:40f83904f0a8 24 * Example:

nxp_ip 3:40f83904f0a8 29 * PCA9632 led_cntlr( p28, p27, 0x3E ); // SDA, SCL, Slave_address(option)
nxp_ip 3:40f83904f0a8 30 * LedPwmOut led( led_cntlr, L0 );
