Sad Z-Wave and openzwave+node-openzwave-shared
Posted by: saro - 08-31-2017, 08:39 AM - Forum: POT modules - Replies (2)

Hi,

I've installed the Ubuntu 16.04 Longsleep image and then I use the Z-wave EU pot module on euler bus.
Installing openzwave library (at openzwave) and node wrapper (at  openzwave-shared).
It works correctly with the ZW090 Z-Stick Gen5 EU USB device (accessed on /dev/ttyACM0)
but with official pine64 z-wave pot module, on discovery, I don't found any device (the access setting in on the correct /dev/ttyS2).
The pine64 module is well found on /dev/ttyS2 interface but the at scan complete it show 0 device.
Here the 2 logs:

Somebody help me, please?
Thanks in advance.
PS. I would avoid to use OpenHAB.


  What are the differences between the A64+, 64-LTS (and Rock) versions?
Posted by: WhiskerBiscuit - 08-31-2017, 08:28 AM - Forum: General Discussion on PINE A64(+) - Replies (12)

I'm currently using an ODROID to provide OpenVPN services, however I also want to start to allow streaming media to clients.  The media server I want to use (AirVideo server, for iOS clients) doesn't come in a 32 bit package so I need to switch to a 64bit SBC.

First question.  What is the difference between the A64+ and the 64-LTS?  For the 2GB A64+ the only difference that I can detect is the LTS has an EMC slot and costs 3$ more.  Am I missing something else?

The new ROCK version looks intriguing.  But is it worth the extra money?  As I said, I want to use this to stream media to clients, but the specs look compatible with the Air Video Server for Linux.

Your guidance is appreciated.

  How to Configure Screen Brightness in mate on pinebook via terinal?
Posted by: shirman - 08-31-2017, 05:50 AM - Forum: Linux on Pinebook - Replies (6)

I'm trying to bind brightness change to buttons via terminal in i3, but I can't find a command that will doing that:

Code:
pine64@pinebook:~$ sudo xrandr --listmonitors

Output is:

xrandr: Failed to get size of gamma for output default

Monitors: 1
 0: +*default 1366/361x768/203+0+0  default

So, when I trying to change it like:
Code:
pine64@pinebook:~$ sudo xrandr --output default --brightness 0.5

It isn't do anything. 

Code:
pine64@pinebook:~$ echo 240 > /sys/class/backlight/lcd0/brightness


Have not do anything too Sad


  Install pygame in Ubuntu Mate

Hi all, I have been trying to install pygame using pip and have been unsuccessful so far. Has anyone had success. SO far I have installed build-dep python-pygame and libfreetype6-dev dependancies based on stack overflow searches.

My latest error is:

  Wake on LAN (WOL)
Posted by: MORIN-KHUUR - 08-30-2017, 09:09 AM - Forum: Rock64 Hardware and Accessories - Replies (2)

hi everyone. i tried WOL. working OMV on rock64. but not wake up from suspend.
It is shifting to suspend with this command
"pm-suspend"
Also, when shifting from this command to the suspended state, pressing "PWR Btn" will not wake it up.

what should i do?


  Linux app Manuskript on Pinebook

I'd like to install this application, but my first attempt gave an error concerning not being a correct binary image. What considerations do you need to take in looking for applications that run on Linux?


Information Brushless Fan (5v) for Rock64 Clear Case Soft PWM Drive 2N2222
Posted by: MarkHaysHarris777 - 08-30-2017, 12:08 AM - Forum: Rock64 Hardware and Accessories - Replies (7)

See full update on post #2 below:


         


I plan to mount this 5v brushless fan under the clear Rock64 shipping case using very tiny machine screws set directly into the soft plastic ( for a little later ).  The motor leads ( red +5v,  black grnd ) are plugged into the PI-2 bus voltage pins with a 2N2222 transistor in the power lead ( collector emitter ) and with the base lead plugged into the GPIO2_C2 (82) via biasing resistor.  

The theory is that a driver script ( fan_motor.sh ) will generate a soft-pwm signal to the base of the driver transistor allowing current to flow from collector to emitter;  with greatly reduced current, heat, and noise.  I have wrapped the 2N2222 transistor in an aluminum clip ( heatsink ) to help extend the life of the transistor;  the heatsink gets warm but does it's job quite well.

The simple driver script is listed below, and is also visible in the terminal pics below:

fan_motor.sh

Code:
#!/bin/sh
#        sudo ./fan_motor.sh pwm_pin# ctrl_pin# time_ON time_OFF &

while [ `cat /sys/class/gpio/gpio$2/value` -gt 0 ]; do
  echo 1 > /sys/class/gpio/gpio$1/value
  sleep $3
  echo 0 > /sys/class/gpio/gpio$1/value
  sleep $4
done
echo 0 > /sys/class/gpio/gpio$1/value


                     



The pic at the far right-hand is the fan happily spinning away !  The other two pics are views of the control terminal and the commands used to control the 2N2222 transistor bias.  The code sets up a loop that monitors the control pin ( in this case gpio83 ).  gpio83 must be set HIGH to run the loop, which runs in the background.  Momentarily pulling the control pin (83) LOW causes the loop to break and the motor will stop ( the control pin is on parm $2 ).

The control loop turns gpio(82) ON|OFF using parms $3 and $4 with a slow duty cycle in this case of 75% ON, and a frequency of about 6cps;  for a brushless fan this is perfect for keeping the fan running ( very nice airflow ) but with greatly reduced current and far less noise !

The stopled.sh script is simply a three line script that pulls the control pin low for 1.5 seconds and then releases it.  This breaks the control loop effectively stopping the motor.

  uSD Breakout
Posted by: machinehum - 08-29-2017, 06:59 PM - Forum: Pinebook Hardware and Accessories - Replies (32)

Originally inspired by this thread I've decided to make a simple open source breakout PCB with some additional peripherals, essentially it's in the same form factor as a micro sd card, so it will be able to slot into the side of the pinebook giving the user access to some low level GPIO.

I'm just getting started now, I'll be posting updates in this thread as well it's possible to track the commits here.

Check out the github readme for the initial conception + peripherals list.

If you're interested in the project or have ideas/suggestions/feedback I would love to hear them!
