I NEED TO RIGHT A SMALL PROGRAM TO RUN A FREQUENCY UP AND DOWN THRU SERIAL PORT CAN SOME ONE WRIGHT A SMALL PROGRAM TO LOAD AND RUN AND REPET IT UNTILL I STOP IT
HERE IS THE CODE FOR THE UNIT
Communication standard: 9600 bps data bits: 8
Stop bit :1
Check digit :none
Flow control : none
1, set the frequency of the PWM
“F101”: Set the frequency to 101 HZ (001~999)
“F1.05”: Set the frequency to 1.05 KHZ (1.00~9.99)
“F10.5”: Set the frequency to 10.5KHZ (10.0~99.9)
“F1.0.5”: Set the frequency to 105KHZ (1.0.0~1.5.0)
2, set the duty cycle of the PWM
“Dx:yyy”: set the duty cycle of PWM x: (1~3) PWM serial number, yyy: (000~100) duty cycle %;
For example, D1:050, set the first PWM duty cycle to 50%.
3, read the setting parameters
Send a "read" string and read the set parameters.
The read data format is as follows: F156, D1: 052, D2: 059, D3: 058,
Set the success to return: DOWN;
Setting failed to return: FALL.
