I setup wiring on the Orange Pi but was unable to access it through a bridged internet interface.
|
||||
|
||||
I need another ethernet cable, I'm pausing at 11:05AM.
|
||||
|
||||
Resumed at 11:23 with ethernet cable, `arp` isn't giving me anything on where the Pi is.
|
||||
|
||||
You must plug in the ethernet to the Pi after plugging in power. Fing is a good network discovery tool. He ran fing twice before and after we plugged in the pi and ran diff on the two captures.
|
||||
|
||||
AJ tested using a USB cable with exposed cables, Black = ground Red = multiverse
|
||||
|
||||
He hooked them to the board to a resistor to the LED and it worked.
|
||||
|
||||
Green = Black Yellow = Red
|
||||
|
||||
We wired it up with pin 6 (ground and pin 2 VCC3.3V)

I want to setup rocket.chat. I followed these instructions and modified them for the Raspberry Pi https://rocket.chat/docs/installation/manual-installation/ubuntu/
|

Install Node & NPM: `curl -fsSL bit.ly/node-installer | bash -s -- --no-dev-deps`
|

Download: `wget https://releases.rocket.chat/latest/download`
|
||||
|
||||
Decompress: `tar -xvzf download`
|

I had to deal with this issue on my Raspberry Pi:

This didn't work, BUT, the below did:
|
||||
|
||||
The general proceeding is described in https://linux-sunxi.org/GPIO
|
||||
|
||||
The GPIO pins are accessed via the sysfs file system. For enabling a specific pin it has to be exported into /sys/class/gpio/export
|
||||
|
||||
for pin PA1 the command would be echo 1 > sys/class/gpio/export. The pin number is calculated by the following formula :
|
||||
|
||||
(position of letter in alphabet - 1) * 32 + pin number
|
||||
|
||||
PA1 has pin number ('A' is the 1st letter ) 1, PB2 has pin number 34 ('B' is 2nd letter ), PG7 has pin number 199( 'G' is 7th letter (7-1) * 32+7=199 )
|
||||
|
||||
the positions on the physical header are different again, cf. the graphic below
|
||||
|
||||
so for enabling PG7 that is pin 40 on the physical header can be used
|
||||
(# echo "out" >/sys/class/gpio/gpio5/direction first)
|
||||
echo 199 > sys/class/gpio/export
|
||||
|
||||
Then you can run `echo "1" >/sys/class/gpio/gpio2/value` to turn it on and `echo "0" >/sys/class/gpio/gpio2/value` to turn it off.
