Re: [Gumstix-users] Robostix 5v GPIOs

[Dustin W. <dus...@ya...>]

Hi Adam:

I was recently looking to do basically the same thing when I came across the Robostix i2c-io page. Check it out <http://docwiki.gumstix.org/index.php/Robostix_i2c_io>. Basically it's a two part program. One part that runs on the ATmega128 and one part that runs on the Gumstix. The combination of the programs allows you to do what you desire I believe though i must admit I haven't used it yet.

HTH,
Dustin Webb

Thanks Dave

I have no programing experience for the ATmega128 before, what is the easiest way to set the 5v gpio from a program running on the gumstix or is this not possible?

Hi Adam,

They don't. The /proc/gpio stuff corresponds to gpios which are
connected to the gumstix. The 5v gpios on the robostix and robostix-TH
are connected to the ATmega128.

About the only pins available on the robostix which are connected
through to the gumstix are the following:

FFUART-TxD
FFUART-RxD
STUART-TxD
STUART-RxD

The SCK signal on the robostix connects through to the NSSPCLK on the gumstix.
The SDA and SCL signals on the robostix connect through to the SDA and
SCL signals on the gumstix.

On the roboaudiostix, the MOSI and MISO signals connect through to the
X_MOSI and X_MISO on the gumstix.
