    7-Segment LED Display Module (HT16K33)

    Or this one:

    https://www.raspberrypi-spy.co.uk/2018/11/raspberry-pi-7-segment-led-display-module-using-python/

      

    orangepi@orangepiplus2e:~/Adafruit_Python_LED_Backpack$ sudo python3 7segment_counter.py
Traceback (most recent call last):

    And this one based on SMBus that i installed previously:

    https://github.com/emcconville/HT16K33

      

    sudo python3 clo.py

    !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    ! Unable to load SMBus            !

    But does not work either.

    I tried this one based on micropython but when i install trought pip returns many errors: 

    sudo -H pip3 install adafruit-circuitpython-ht16k33
...
 error: invalid command 'bdist_wheel'

  ----------------------------------------
  Failed building wheel for Adafruit-Blinka

...

  ----------------------------------------

    And many more. Also it needs busio and board but can't find it. Also i installed adafruit-blinka alone (https://pypi.org/project/Adafruit-Blinka/) what have busio and board drivers, but it doesn't work either. The instalations is success, but after that the code can't find busio or board:

    7-Segment LED Display Module (HT16K33)

    in Allwinner sunxi

    Posted

    Is it even possible to run the 7-segment HT16K33 module with Armbian and Orange Pi?

     

    I'm trying with I2C and SMBus2 but can not make it work. I can see the module, but it is imposible to communicate with it:

      

    sudo i2cdetect -y 0
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

    Any help will be apreciated. Thank you in advance.

    Problems with Thermal zone and DS18B20

    in Allwinner sunxi

    16 hours ago, martinayotte said:

    You should not place any W1 driver in /etc/modules-load.d/modules.conf ...

    You should rely on DT overlays : https://docs.armbian.com/User-Guide_Allwinner_overlays/

    ... and more specially to H3 W1-Bus overlay parameters : https://github.com/armbian/sunxi-DT-overlays/blob/master/sun8i-h3/README.sun8i-h3-overlays#L231,L250

     

    Yes. Thank you martinayotte. If sombody needs that, i just have to add this lines to '/boot/armbianEnv.txt' 

    overlays=w1-gpio
param_w1_pin=PA20
param_w1_pin_int_pullup=1

    and works like a charm! Thank you very much.

    Problems with Thermal zone and DS18B20

    in Allwinner sunxi

    Posted

    Hi. Recently i upgraded to Armbian_5.65_Orangepilite_Debian_stretch_next_4.14.78 and i have two problems. I can not read the thermal zones properly with neither of those: 

    cat /sys/class/thermal/thermal_zone0/temp
cat /sys/devices/virtual/thermal/thermal_zone0/temp
cat /etc/armbianmonitor/datasources/soctemp

    because i have results like "30371". But when the system starts the correct temperature is displayed: 

    Welcome to ARMBIAN 5.73 stable Debian GNU/Linux 9 (stretch) 4.19.20-sunxi
System load:   0.07 0.15 0.10   Up time:       10 min
Memory usage:  29 % of 493MB    IP:            192.168.1.46
CPU temp:      33°C
Usage of /:    10% of 15G

    and with armbianmonitor too:

      

    Time        CPU    load %cpu %sys %usr %nice %io %irq   CPU  C.St.

17:39:34: 1200MHz  0.06   3%   1%   1%   0%   0%   0% 34.6°C  0/15
17:39:39:  480MHz  0.06   1%   0%   0%   0%   0%   0% 31.5°C  0/15
17:39:45:  480MHz  0.13   4%   3%   0%   0%   0%   0% 31.8°C  0/15

    My second problem is that my DS18B20 sonda does not work anymore. In /etc/modules-load.d/modules.conf i have: 

    w1-sunxi
w1-gpio
w1-therm

    but there is nothing in /sys/bus/w1/devices/
     

    is there any changes in this new version? I check the forum but i does not found anything. Any iddeas?

     

    Thanks in advance.

    Armbian 5.25 on OrangePI PC: The gc2035 video camera doesn't work

    Cool if it works.

     

    Sorry I didn't remember about the content of gc2035 on github . If it's works fine for you, maybe you have nothing to do ?  Why do you think you have to care about it, maybe  you have some other problems with the video ?

    But... I still have the doubt that what to do with the content of https://github.com/avafinger/gc2035...........

     

    I mean ... i don't know how to build a module. Anyway, all it's working, so thanks.

    Thanks for your feedback. As olivluca suggest, I think the first step you can try to do is using the 3.X kernel : https://www.armbian.com/orange-pi-lite/ at the end of the page : https://dl.armbian.com/orangepilite/Ubuntu_xenial_default_desktop.7z

    Yes, 3.X kernel have the drivers. Works fine. Thank you.

     

    But... but I still have the doubt that what to do with the content of https://github.com/avafinger/gc2035.

    Thank again.

    GPIO Buttons does not work

    By the way, in my rc.local i have other scripts that runs normally:

      

    #!/bin/sh -e

# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

/etc/init.d/entrehoras.sh
# CÁMARA HP
/etc/init.d/runmjpg.sh
# Cámara GEMBIRD
#/etc/init.d/runmjpgGEMBIRD.sh
nohup python /home/orangepi/scripts/botones.py > /tmp/botones.log 2>&1
#/etc/init.d/botones.sh
exit 0

    Well, now the consume of CPU lower to 0,1%... thank you very much.

     

    BUT... still dying. The file is in /etc/init.d/ and have +x permission. The file starts but after a while dies.... The Python file is called "botones.py". In syslog:

      

    Nov  7 16:31:03 localhost systemd[1]: botones.py.service start operation timed out. Terminating.
Nov  7 16:31:03 localhost rsyslogd-2007: action 'action 17' suspended, next retry is Tue Nov  7 16:31:33 2017 [try http://www.rsyslog.com/e/2007 ]
Nov  7 16:31:03 localhost systemd[1]: Failed to start (null).
Nov  7 16:31:03 localhost systemd[1]: Unit botones.py.service entered failed state.

    If i run from the monitor, never dies....

    GPIO Buttons does not work

    in Allwinner sunxi

    Hi. I have made a system with O Pi Lite and Armbian to automate an aquarium from where to control the light, the bubbles and with a webcam I can see the system through the web, everything automated from Cron. From a web page I can turn on and off the lights and bubbles from web buttons. Everything is fine.

    The problem arises when I want to put some phisical buttons for 3 things: turn off the system, change the state of light and bubbles. I have used a code in Python and the PYA20 library. This is the code. It works very well, but when I start it with the system, the program stop working soon and the buttons stop to work.

      

    #!/usr/bin/env python
from pyA20.gpio import gpio
from pyA20.gpio import port
import subprocess
import time
import os

# PIN 29 - IN Light (luz)
onoff = port.PA7
# PIN 7  - IN Bubbles (burbujas)
luzboton = port.PA6
# PIN 8  - IN Shutdown
burbujasboton = port.PA13
# OUT Pins
luzvivo = port.PA8
burbujasvivo = port.PA9

gpio.init()
#Button ON-OFF
gpio.setcfg(onoff, gpio.INPUT)
gpio.pullup(onoff, gpio.PULLUP)
#Button light
gpio.setcfg(luzboton, gpio.INPUT)
gpio.pullup(luzboton, gpio.PULLUP)
#Button bubbles
gpio.setcfg(burbujasboton, gpio.INPUT)
gpio.pullup(burbujasboton, gpio.PULLUP)
# OUT
gpio.setcfg(luzvivo, gpio.OUTPUT)
gpio.setcfg(burbujasvivo, gpio.OUTPUT)

while True:
    # PROCESS ON-OFF need 5 seconds to avoid mistaken shutdowns
    if gpio.input(onoff) == 0:
        #start counting pressed time
        print ("pulsado")
        time.sleep(5)
        if gpio.input(onoff) == 0 :
            os.system("shutdown now -h")

    # PROCESS LIGHT
    if gpio.input(luzboton) == 0:
        print ("pulsado luz")
        estadoluz = gpio.input(luzvivo)
        gpio.output(luzvivo, not estadoluz)
        time.sleep(1)

    # PROCESS bubbles
    if gpio.input(burbujasboton) == 0:
        print ("pulsado bubbles")
        estadoburbujas = gpio.input(burbujasvivo)
        gpio.output(burbujasvivo, not estadoburbujas)
        # To avoid bounce
        time.sleep(1)

    If i check the procces, i can see it, but i can also see that consumes a lot of CPU:

      

    ps aux | grep botones
root       652 95.1  0.6   8552  3412 ?        Rs   10:53   2:36 python /etc/init.d/botones.py start

    What i am doing wrong?

     

    Thank you in advance.
