Console Pixel
|
|
|
|
An example of using YunShield/Yún board to receive data from the
|
|
Console on the Yún. In this case, the board turns on an LED when
|
|
it receives the character 'H', and turns off the LED when it
|
|
receives the character 'L'.
|
|
|
|
To see the Console, pick your Yún's name and IP address in the Port menu
|
|
then open the Port Monitor. You can also see it by opening a terminal window
|
|
and typing
|
|
ssh root@ yourYunsName.local 'telnet localhost 6571'
|
|
then pressing enter. When prompted for the password, enter it.

* LED connected from digital pin 13 to ground
