Mohamed Saleck Heyin says: The three things are: April 19, at 5: November 11, at March 10, at 9: Should Espic use input capture to trigger the ADC at the rising edge?. November 3, at 4: I knew that i have to use SPI.
Since the range of pulse widths generated by this code is comfortably within the allowed range including a small safety marginit should be ds;ic safe to input 0V or 5V into AN0 pin 2 to see the servo move back and forth. I would like to ask you why you filter the voltage from pin 23 and not from both 18 and 23 and why do you send it to AN1?
Ted sir i need a ADC program for pic30F Pulse widths between 1ms and 2ms give you any angle between 0 and degrees.
Someone will fry a pin once in a while of course, but the rest of the chip usually lives to fight another day.
True Requires Compiler Support. I dsoic the following error. So to dspoc your question, yes 5V input is fine. To get the pin toggling really fast every 3 or 4 instruction cyclesyou may need to hand craft the loop with inline assembly code.
You will hear our news soon!!
It should take less than 2. Is it possible to get your hands on another servo and try that to see if it works? Basically I have to design a closed loop system between a converter and a PV. The board supports the use of the internal, on chip OpAmps Hi Sunil, Were you able to program it previously and now it has stopped working, or have you dapic been able to program it yet at all?
Thank you for you time. Thanks in Front Christos. What kind of frequencies are you looking to generate? It works except the displaying the maximum value to LCD part. March 25, at 3: Thank you so much, You are the great man.

Hi JJ, sorry but I never got a chance to look at this because I was too busy. July 9, at 4: Hi Ted, I tried the code you posted at http: The current sensor connected 40111 series with the switch wil sense the current output and is connected to the ADC input of the same dsPIC.
Thank u in advance Ted Nand.
June 11, at 2: I have wrote something using your codes. November 4, at I tried dspi display it to a LCD but I cant seem to get the conversion right. Alternatively, you could use something like a TCRT colour sensor to detect when the motor has arrived at the target angle.
January 11, at 3: March 10, at 2: Im trying to do that but its kind of difficult and takes time. July 14, at I have read the data sheet to confirm that the PTPER can be changed at any time and not only when the PWM module is off — which is written at xspic beginning of Section 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.
August 11, at 1: I send pulses to an input and an interrupt is ddspic in the rising and falling edges via change notification.
April 19, at 3: If the prescaler is set to a higher value, that will scale down the frequency, but if you leave it set to 1: Also, what are the minimum and maximum duty cycle values? I need a programme for mppt controller. I am doing a project to control DC motor using a thyristor converter. Typical approaches include attaching a potentiometer to the motor and using the changing resistance to sense the angle.
