Hi all,
sorry for my english  Grin
I'm newbie of dSPIC30F  Shocked.

Always I have used CCS C Compiler for 8-bit MCU, but now I have tested the PCD Compiler and I have seen that there are too bugs and not all function have been implemented.
So, I have decided to use for the first time C30 C compiler  Grin
I have downloaded all documents, sheets, e-books but this compiler is a bit different from CCS and less intuitive Shocked

Can somebody upload some example for dSPIC and C30 Compiler?
On the net there aren't many sources  Cry
I'm searching especially for PWM sources  Cheesy

Thanks for all Wink
Bye

Hi, PWM exapmle is directly in the MPLAB C30 examples directory - CE003_Sinusoidal_BLDC.


And few another complete examples (with MPLAB workspace) you can download from microchip page with demo boards:

Code:
http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=2519&param=en025319&page=wwwdsPICDSCDemo

But PWM there's not (I think)...

Hi this is code for simple PWM operation:--
PR2=16582;//--->desired PWM period (calculated from eqn. given in datasheet)
OC1CON=0x06; /*configure the pwm channels according to operation*/
OC2CON=0x06;
OC3CON=0x06;
OC4CON=0x06;
T2CONbits.TON=1;//run the pwm timer (either timer2 or timer 3,inthis case timer 2)
T2CONbits.TCS=0;
OC1RS=pos1;//program each compare value
OC2RS=pos2;
OC3RS=pos3;
OC4RS=pos4;
