pwmGenerator can be used to generate PWM signals or variable frequency. With these PWM pins [iCP12: RC1, RC2], user can easily to control PWM signals width (0% - 100% @ 8-10bits resolution) with different frequency setting and direct command from COM port.

The features of pwmGenerator are listed as followings:

• PWM width control at 8-10 bits resolution
• Width ratio, percentage and DAC voltage display 
• Adjustable frequency from 3kHz to 200kHz
• Command line x3 to allow user to transmit iCP12 command

Supported Operating System: 

• Windows OS

Supported Models: 

• iCP12 - usbStick with [iCP12_DAQv1.2_Firmware.hex]

Command Line: 

• The command lines are using the ASCII format
• Transmit format: ( xxxxx ), Reply format: < xxxxx >
• Following commands are available in the communication interface:

• Function	Data	Command	Ack/Reply
  PM (PWM)	(PM| Port: 1b | Type: 1b : Value : 4b)
  e	PMxe: Enable PWM1, x: 1,2	(PM1e)	#
  d	PMxd: Disable PWM1, x: 1,2	(PM1d)	#
  f	Set PWM1 with Frequency 3kHz,  Freq (Hz): 3k - 200k (PWM1 & 2 same freq)	(PM1f:003k)	#
  r	Set PWM1 with Ratio 50%,   Ratio: 0-1023	(PM1r:0512)	#
