Question

hardware PWM is available on which of the raspberry pi3 pins?
a. GPIO 12 and 13
b. GPIO 18 and 19
c. both a and b
d. none of these ​

Answer 1

Answer:

c.both a and b

Explanation:

gpio can be used veriety of alternative functions

Answer 2

Answer:

Hardware PWM is available on - option c) both a and b that is both GPIO 12 and GPIO 13 of raspberry pi3 pins.

PWM stands for Pulse Width Modulation that generates signal which in turn varies the duty cycle at fixed period.

These cycles are of square waves. Hardware PWM was implemented on XC4005XL FGPA of Xilinx.

With 8051 microcontroller the interface becomes very easy to do and that is allowed by a circuitry that hardware PWM contains.
