Pulse-width modulation,as it applies to LED control, is a way of delivering energy through a succession of pulses rather than a continuously varying (analog) signal. Through PWM technique, we can control the power delivered to the load by using ON-OFF signal. The PWM signal is an alternating waveform that keeps changing from 0 to 1 and from 1 to 0. The frequency of this generated signal for most pins will be about 490Hz and we can give the value from 0-255 using this function. When you select a MCU, mikroC PRO for AVR automatically loads the correct PWM library (or libraries), which can be verified by looking at the Library Manager. 16-channel, 12-bit PWM Fm+ I2C-bus LED controller The active LOW Output Enable input pin (OE) allows asynchronous control of the LED outputs and can be used to set all the outputs to a defined I 2 C-bus programmable logic.
