Hi

I have written a PWM basic application, with the following features:

AT91SAM7S64-PWMAudio-IAR4_11A-1_1.zip

- Constant generation
- sinus generation :P
- audio generation

You can get to the forum fpt

ftp://81.80.104.162
User: at91dist
Password: distrib
folder:
AT91SAM7 Series/SAM7S_SOFT/IAR/

Please check the KIT menu the kit AT91SAM7S or AT91SAM7S64-IAR, select the software for AT91SAM7S64, you can check the text file or dowload the zip file :wink:

hi ,

yes I know it's available as a sticky on the forum, but it's not the same version as the one that was posted a long time ago... the original was using an interrupt on the PWM and a software interrupt to generate the sound?

thanks,
bert

Hello,

I´m searching for the example "AT91SAM7S64-PWMAudio" but I can´t find it.
Can someone tell me where I can find it?

Thanks

Lost in the mists of time and the black hole that is the SAM7 forum!
If anyone can find an old copy, please repost.
Attachment in the PWM DAC sticky vanished 2 years ago!

Funny.. its turned up on a dodgy software site.. this is the only place I can find it!
