It seems to me that it would be much simpler to use an interrupt to generate the gate pulses at a regular interval 2 seconds and include the analog sampling in the same interrupt service routine that generates the gate pulse. March 31, at However, it would be useful to know some more details, such as the voltage range of the two input signals, etc.

The three things are:. Hi Christos, What is the relationship you need to implement between the V input signal and the duty cycle? I have heard of your forum and how helpful you are with students having difficulties in programming and I would like to ask for your help. Dear Mr Ted hello, its now three weeks I am struggling with the programming part of my project.

April rspic, at 2: Also, perhaps you can you sspic a bit more about the rest of the circuit and what your code is doing? I create a new folder for every dsPIC program I write. After the PWM will start in the independent mode. Here is the code: Is it possible that WordPress has swallowed some important lines in the program? February 11, at 6: To find out more, including how to 401 cookies, see here: The problem is on synchronization of the thyristors with a phase source voltages.


dsPIC30F4011 Examples

Hello Mr Ted, I would like to ask you if you have my simulink files I have sent you vspic other time. June 21, at 8: The two anti-phase pulses can overlap in time? Here is the code:.

My understanding is that DDS usually uses a digital-to-analog converter which is not included within the dsPIC30F and that DCO uses a separate analog oscillator that is under the control of the microcontroller.

Hi Ted, Based on a multimeter, the output is about 2.

May 8, at December 31, at To run the build script, open a console window, navigate to the folder 40111 your program files are located, and type the following command:. What sort of example are you looking for? Your Help is highly appreciated. There are a couple of things about the PWM module that seem unnecessarily complicated to me. January 11, at 3: June 14, at dspiv Could you help me?

Could you possibly share a high resolution photo of your circuit with the PICkit 3 connected? This reference is one sinus, which has frequency 50Hz and i control its peak and its dc value through two trimmers respectively. September 1, at I want the ADC to sample and convert just once at the rising edge of the gate pulse.


Dear Ted, How are you? Hi TedI tried running the build. So to answer your question, yes 5V input is fine.

The input voltage is 84 and should be matched by changing the duty cycle in order ds;ic get maximum power. For example, you could use something like a limit switch at each end of the range of motion to tell the microcontroller when the motor has arrived at the target position.

June 7, at 5: Also, have you tried just feeding in 0V and 5V or whatever Vdd you use in your circuit into the analog input to see if it responds to that? Hi Ted, I have the question again. Dear Ted, I am sorry to post n irrelevant question dxpic.

I know you have a lot of work to do and I do understand. Kindly help me for generating the pwm pulses which are phase shifted as said above.
