PWM 2 Channel Signal Generator Module for Square and Rectangular Wave

2 Channel PWM Pulse Frequency Adjustable Duty Cycle Square Wave Rectangular Wave Signal Generator Module to generate square wave for experiment development.

This is used to drive stepping motor drivers square wave, Generate adjustable pulse for MCU using, Generate adjustable pulse for controlling relative circuit (PWM adjust lightspeed etc).

Serial Port Control:

Communication Standard:9600 bps

Data Bit:8

Stop Bit:1

Verify Bit: none

Flow Control: none

Setting PWM Frequency:

S1FXXXT: set PWM1 frequency as XXX HZ (001~999)

S1FXX.XT: set PWM1 frequency as XX.X KHZ (00.1~99.9)

S1F:X.X.X.T: set PWM1 frequency as XXX KHZ (0.0.1.~1.5.0.)

S1: PWM1

S2: PWM2

F: frequency

D: duty cycle

T: stop sign bit

Setting PWM Duty Cycle:

S1DXXXT:set PWM1 duty cycle as XXX(001~100)

S2DXXXT:set PWM2 duty cycle as XXX(001~100)

Setting successfully back: DOWN

Setting unsuccessfully back: FALL

Parameter Setting:

The module has a 3-channel key: Set, Up, Down

By short press SET key,can shift display 4 parameter values (FR1:PWM1 frequency;dU1:PWM1 duty cycle;FR2:PWM2 frequency;dU2:PWM2 duty cycle);before shifting,there will be corresponding parameter name flashing

Directly press UP, DOWN key to modify the current parameter value

2-channel PWM is set 3 kinds frequency value, in frequency display interface, by long press SET to shift,3 kinds frequencys duty cycle is the same XXX:1Hz~999Hz; XX.X:0.1Khz~99.9Khz; X.X.X.:1Khz~150Khz).
