Hello all, I am just a beginner of this programming. Can any one help me with some useful points. please help me. Thank you
What do you want as a response, a how-to book? Your question is extremely vague and gives no indication of what you know and don't know.
I suggest buying the book "Programming 16-Bit PIC Microcontrollers in C: Learning to Fly the PIC 24". http://www.amazon.co.uk/Programming-16-Bit-PIC-Microcontrollers-Learning/dp/1856178706/ dsPIC is PIC24 plus DSP extensions, so this book is usable for you. There is another book, which I haven't read. http://www.amazon.co.uk/Beginners-Guide-Programming-Pic24-Dspic33/dp/1468152637/
