PWM signal generator with screen
The PWM Signal Generator with screen is capable of generating a square wave signal for experimental development that involves PWM dimming and speed controlling (e.g. motor drivers) as well as other microcontroller use. It can be controlled via the Serial Protocol TTL (TXD & RXD pins). It is stable and reliable, and fairly simple to use.

Serial Communication
- Setting the frequency of the PWM:
- Command "F101": Set the frequency to 101 HZ (001 to 999)
- Command "F1.05": set the frequency of 1.05 KHZ (1.00 ~ 9.99)
- Command "F10.5": Set the frequency to 10.5KHZ (10.0 ~ 99.9)
- Command "F1.0.5": set the frequency of 105KHZ (1.0.0 ~ 1.5.0)
- Setting the PWM duty cycle:
- DXXX": set the PWM duty cycle to XXX; (001 ~ 100)
- Example: "D050", sets the PWM duty cycle is 50%
- Read the set parameter
- Send a "read" string to read the set parameters
- Set successfully return: DOWN
- Setup failed to return: FALL
