hello friends,
how can i generate a PWM control 2 kHz with PIC16F84

PWM (Pulse Width Modulation) control is a technique used to regulate the amount of power going to a device by varying the width of a pulse signal. With the PIC16F84 microcontroller, PWM control is achieved by using the CCP (Capture/Compare/PWM) module, which allows for precise control of the pulse width and frequency.
The PIC16F84 has two CCP modules, each with a dedicated PWM channel, allowing for two independent PWM outputs.
Yes, the duty cycle and frequency of the PWM output can be controlled by configuring the CCP module’s registers. The duty cycle can range from 0-100%, and the frequency can be adjusted within a specific range depending on the system clock frequency.
The resolution of the PWM output on the PIC16F84 is 10 bits, allowing for fine adjustments of the duty cycle with a range of 0-1023.
While PWM control is suitable for many types of devices and loads, it may not be suitable for some sensitive or high-frequency devices. It is important to consult the device’s datasheet to ensure compatibility with PWM control.
