RE: AT91 ADC support

["Christophe Coutand" <ccoutand@stmi.com>]

Hi,

I originally made it for AT91SAM7S and AT91SAM7X but at the last minute
I saw that Atmel was using the same ADC for AT91M55800A, AT91SAM9X etc..
so I renamed it to AT91. I thought this would be more future proof.

It remains true that I have not compiled / tested it for anything else
than AT91SAM7S / AT91SAM7X.

I can specify which AT91 supports it and update the var_io.h when
definition are missing.

Regards,
Christophe

Hi John,

First I tried to build the driver for AT91 'phycore' target and it was
not possible to build it because in AT91 var_io.h some ADC defines
included by a condition:

...
#elif defined (CYGHWR_HAL_ARM_AT91SAM7)
#include <pkgconf/hal_arm_at91sam7.h>
...

So, it seemed for me that's AT91SAM7 related driver. I have no
experience with AT91 CPU set. May be Christophe enlighten us?

Thanks for your point. It seems I must dive in AT91 datasheets.

Sergei
