Is it possible to access pins from Linino without the Bridge ?

Hardware Arduino Yún
#1

Hi,

I was thinking in something similar to the /usr/bin/blink-start script which uses:

/sys/class/leds/ds:green:wlan/

to turn the wlan led on/off.

I tried looking at the schematics available (http://arduino.cc/en/uploads/Main/arduino-Yun-schematic.pdf) but could not figure out if GPIO 13 is actually connected to Pin 10 (P10) ?

Thanks in advance for any help,

What you are asking is AR9331 direct GPIO access. The answer is no.

AR9331 has:

  • I2S/SPDIF-out audio interface
  • SLIC for VOIP/PCM
  • GPIO/LED support (GPIO0~GPIO28)
  • JTAG-based processor debugging supported

In total 29 of GPIO pins some of them are multiplexed pin with UART,I2S,LED,SLIC, JTAG.

Yun breaks out 0 of them. We are out of luck.

OK, too bad.

thanks for the reply sonnyyu,
