Ted, We tested today at the lab the source code you sent me and worked fine. I have the PWM buck converter working perfectly. Hi Payrav, It sounds like you need something like this: Max PWM outputs including complementary.
The development board also comes Hi 0411, Sorry for spamming but I made a mistake.

Mike on Simple command line trick for…. Hardware Conditioning of Sensor Signals. Thank you for your time, Regards, Song. Hi JJ, sorry but I never got a chance to look at this because I was too busy. November 3, at 4: March 10, at 9: I need a programme for mppt controller. Hi Ranjithh, Here are a couple of example from earlier blog posts — one uses the PWM module, the other dspkc the output compare module. You will hear our news soon!!
If your servo is supposed to have a maximum travel of degrees, but yours is rotating continuously revolving around and around in the same directionI suspect it may be faulty.
It also has hardware support for sensor and sensor-less applications such as Hall sensors, optical encoder, back EMF and current sensing.
Best of luck getting it finished! I want to make it so that the can read a flex sensor and control a servo.
Basically I have to design a closed loop system between a converter and a PV. The input to the dummy plant is the PWM signal and the output is the capacitor voltage. Hi Nand, Sorry about the delay.
Hi Payrav, Sorry, I forgot to reply to your comment. The irradiance value will affect the output voltage of the PV and with the help of a PI controller I have t track the maximum power point. The problem is on synchronization of the thyristors with a phase source voltages.
As in the chip is destroyed and cannot be used again?? Incidentally, a PI dzpic is just the same as a PID controller with the derivative term set to zero — i. January 21, at 5: Give it a try and see if it works.
December 31, at 1: March 28, at 1: July 28, at The next step is to test the whole circuit on breadboard. Buy from the Microchip Store.
Thanks a lot in advance mr. As you can see from my simulink file attached, the reference point of my PI is by a s-function that I have done. The variance go through one PI controller, with limited output between 0. Also, have you tried just rspic in 0V and 5V or whatever Vdd you use in your circuit into the analog input to see if it responds to that? If you hear the servo grinding in what sounds like a bad way, turn off the power and double check everything! When TMR2 reaches the same value as PR2 the period register for Timer 2dsipc resets to zero and starts counting up again.
The code has a static setting having a constant off-time of 6. I do have everything working perfectly well in Simulink but I have too many troubles converting all this into real C-programming. Is there a particular sampling frequency that I should use for the controller? Can you post it online and include a link in your reply?
Can you give me one suggestion about 4011 structure of the program and especially about the two trimmers.
If so, there are a couple of ways to do it: It might help if you can show me your simulink model. I am doing a project to control LED blinking using dspic30f The register TMR2 will be counting up from 0 to its maximum value in steps of 1. Is it possible that WordPress has swallowed some important lines in the program? Hi Ted, I dapic the question again.
