2 CHANNEL SIGNAL GENERATOR MODULE FOR SQUARE AND RECTANGULAR WAVE

2 channel PWM/Pulse generator with variable Frequency from1hz to 150Khz and Duty cycle 1% to 100% alterations. The frequency and duty cycle can be controlled using switches provided on board.

It gives an easy solution for driving stepper motors using variable frequency pulse input and DC motor with variable PWM duty cycle.

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).

Applications:

• • As square wave generator to generate square wave for experiment development
  • Used to drive steeping motor driver’s square wave
  • Generate adjustable pulse for MCU using
  • Generate adjustable pulse for controlling relative circuit (PWM adjust light speed etc)

Package Includes:

• • 1 X 2 Channel PWM Pulse Frequency Adjustable Duty Cycle Square Wave Rectangular Wave Signal Generator Module
