# Omega2 PWM
This is simple program to control hardware PWM on Omega2. For some reason Omega2 has not any util to control **hardware** PWM. There is only **fast-gpio** tool, it uses software PWM which is awful for sound generation.
## Usage
Channel #0 is pin #18, channel #1 is pin #19. Channels #2 and #3 are available on Omega2S only (UART2 pins).
Before usage you must set GPIO muxing using **omega2-ctrl** tool:
omega2-ctrl gpiomux set pwm0 pwm
or
omega2-ctrl gpiomux set pwm1 pwm
Then use this tool:
pwm <channel> <frequency> [duty]
Example to generate 3000Hz on channel #1 with 50% duty:
pwm 1 3000 50
