dsPIC_PWM_motor.tlc problem

Post by Ebap » Wed Jun 06, 2012 5:36 am

Hi Lubin,

I am trying to do a simple program with the dsPIC_PWM_motor block but when I try to generate the code from matlab, it give me this error ''The + operator only works on numeric arguments'' (In the dsPIC_PWM_motor.tlc) I attach the error file, the installation file and the .mdl.

I am also affected by this problem. Any progress on a fix or suggestions for a workaround?

Thanks

EDIT: the error does not seem to appear when compiling for certain chips (e.g. 33FJ218MC or 33FJ256MC series), but does for the chip that I am using (33FJ32MC204)

Actually I am able to compile the resulting code in MPLAB and run it even though the build (in Matlab) aborts with an error!

The MPLAB project is not created - but I can use a previous project file created without the PWM block in the system.
The file "dsPIC_OutputCompare_Interrupt.c" is not found but it is replaced with an object file.

Ok, Thanks for your feedback,

(As I am not very responsive at that time !)
We're preparing a new blockset suporting newer chips at Microhcip...

PWM DC Motor

Hi Lubin,

I am trying to do a simple program to active DC motor. But when I try to generate the code from matlab, it give me this error ''Error building Real-Time Workshop target for block diagram 'motor1'. MATLAB error message: Error(s) encountered while building model "motor1".I attach the motor1.mdl below. The motor driver frequency is 40Khz. Thanks.
