2 Channel PWM Generator Wave Signal Pulse Width Frequency Duty Cycle

Modul pembangkit gelombang PWM untuk 2 Channel secara independen, artinya kita dapat mengatur duty cycle dan frekuensi tiap channel secara terpisah.

Mampu menghasilkan frekuensi 1Hz s/d 150KHz dan duty cycle dari 0 s/d 100%, selain setting via push button yang tersedia, juga bisa diatur via serial TTL (dihubungkan ke microcontroller / arduino)

**Aplikasi:
1.As square wave generator to generate square wave for experiment development
2.Used to drive stepping motor driver’s square wave
3.Generate adjustable pulse for MCU using
4.Generate adjustable pulse for controlling relative circuit (PWM adjust light speed etc)

**Fitur:
– Volt: 5 ~ 30V DC via socket header or 5V DC via USB
– 2 Ch independent PWM output
– Adjustable PWM freq: 1Hz ~ 150kHz
– Adjustable PWM duty cycle: 0 ~ 100%
– Manual adjustment via push button
– Remote adjustment via serial interface
– TTL level output (5 Vp-p)

Setting PWM Frequency:
1.”S1FXXXT”:set PWM1 frequency as XXX HZ (001~999)
2.”S1FXX.XT”:set PWM1 frequency as XX.X KHZ (00.1~99.9)
3.”S1F:X.X.X.T”:set PWM1 frequency as XXX KHZ (0.0.1.~1.5.0.)
4.”S1″:PWM1
5.”S2″:PWM2
6.”F”:frequency
7.”D”:duty cycle
8.”T”:stop sign bit

Setting PWM Duty Cycle
1.”S1DXXXT”:set PWM1 duty cycle as XXX?(001~100)
2.”S2DXXXT”:set PWM2 duty cycle as XXX?(001~100)
Setting successfully back:DOWN
Setting unsuccessfully back:FALL
Parameter Setting
Module has 3-channel key:Set,Up,Down
1.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
2.Directly press UP,DOWN key to modify current parameter value
3.2-chhannel PWM are set 3 kinds frequency value,in frequency display interface,by long press SET to shift,3 kinds frequency’s duty cycle are the same XXX:1Hz~999Hz
