Hi,

I found some problem on the DemoBoard PWM. The calling function of the PWM \"EE_pwm_set_duty_f\" under flex_daughter_pwm.c\" calls the function via:

EE_pwm_set_duty_f( pin-1 , *duty);

so the chan = pin - 1, in which 0 = 1 in the DemoBoard PWM block under scicos.

However, the chan is define as:
#define EE_PWM_PORT1 1
#define EE_PWM_PORT2 2

in ee_flex_demoboard.h, resulting the \"swith case\" would recognized only 1 channel (recognize channel 1 as 2), while the channel 2 is not recognized.

I think it should be either changing the define chan to:
#define EE_PWM_PORT1 0
#define EE_PWM_PORT2 1

or the pin-1 to pin in the calling function.

Thanks.

Dear Tan Chin,

Thanks!

I guess we can just put in place of \"pin-1\"... in that way the channel should be ok...

I tell taht to Dario and then we are going to update the SVN... (this patch will be released with the next update of the eclipse plugins...)

Grazie!

Dear Tan Chin,
thanks for your help.
I made the following changes.

Hi Dario,

Thanks, it works fine. :)
