I am doing a project to control DC motor using a thyristor converter. The duty ratio value can be between 0. I thing it should be in the Mhz values.
Could it be possible you have any information related to dspic33F family controllers? Hi Ted, My gate signal has a time period of 2 seconds and an on time of 1ms.
I just realised I never got back to you after you responded with additional details. Hi Ted, Thank you for your reply. The PICkit 2 applicationwhich can also be downloaded free of charge from microchip.
Kindly help me dspiic generating the pwm pulses which are phase shifted as said above. The download is about MB in size.
Can you give me some more details of your application please? Here is the code:.
Hi Ted, your example around an LED blinking was very useful. What is the relationship you need to implement between the V input signal and the duty cycle? February 5, at 3: I tried with dspoc. March 25, at 6: I enabled the UART at baud so that debugging info can be printed.
Then you can dspiv just hover the mouse pointer over the variable and its current value will be displayed, or you can add the variable to the watch window so that its value is displayed all the time.
April 22, at 4: It might help if you can show me your simulink model. The ADC reading will keep fluctuating from to normally and when I bend the sensor, at most it will increase the value by 1. If all is well, the LED should start blinking. If you hear the servo grinding in what sounds like a bad way, turn off the power and double check everything!

January 23, at 3: Thanks in Front Christos. I have the PWM buck converter working perfectly. The XC16 401 compilerwhich is available for free from microchip.
November 3, at 4: Hi Ted, I have the question again.
I have not been able to cspic the code you have prepared for me. If you do need to vary the duty cycle, will the value be the same for both waveforms or could they be different from each other?
July 9, at 4: January 21, at 5: I want to make it so that the can read a flex sensor and control a servo. More precisely, I will use a sensor to measure the output voltage from a PV, this sensor is scaled from volts, the information from this has to pass through an ADC and the result from the Ds;ic will be used as dspif reference value of the PI controller.
Hi Ted, Based on a multimeter, the output is about 2.
What software to install. Can you give me one suggestion about dspicc structure of the program and especially about the two trimmers. Thank YOU so much for your time. June 9, at 1: The kind of details I need to know include the following: If so, you normally need to leave a short dead time between switching one off and the other on.
January 23, at 2: Will the code be able to turn my HD servo which can only turn about degrees.
