Orange Pi 5 + Serial port UART1

Place the file rockchip-rk3588-uart1-m1.dtbo in /boot/dtb/rockchip/overlay

~$sudo cp rockchip-rk3588-uart1-m1.dtbo /boot/dtb/rockchip/overlay

Edit armbianEnv.txt

~$sudo nano /boot/armbianEnv.txt

verbosity=1
bootlogo=false
overlay_prefix=rockchip-rk3588
overlays=uart1-m1

fdtfile=rockchip/rk3588s-orangepi-5.dtb

....

~$sudo reboot

~$ls /dev/ttyS*

/dev/ttyS1  /dev/ttyS9

~$screen /dev/ttyS1 1200

You should see teleinfo stream

(Ctrl A k y to exit from screen)

You can also add a link in /dev/serial/by-id to allow some software like domoticz to "view" the port:

~sudo ln -s /dev/ttyS1 /dev/serial/by-id/ttyS1_GPIO

Orange Pi 5 + GPIO + Domoticz

I want to use GPIO's to manage relays with Domoticz and my Orange Pi 5:

Orange Pi 5 GPIO:

Below the outputs I want to manage:

Warning: wiringPi use wPi# but sysfs use GPIO#

That's the trick...

Go to domoticz home directory /home/domoticz or pi or dietpi etc.

- Create a script named sysfs.sh (or what ever) in domoticz directory

~$nano ~/domoticz/sysfs.sh

- Add this:

#! /bin/sh
#-----------------------------------------------------------------------------
# Init sysfs GPIO ports
#-----------------------------------------------------------------------------

#-----------------------------------------------------------------------------
# unexport if needed
#
#echo 6 > /sys/class/gpio/unexport
#echo 9 > /sys/class/gpio/unexport
#echo 10 > /sys/class/gpio/unexport
#echo 13 > /sys/class/gpio/unexport
#echo 15 > /sys/class/gpio/unexport
#echo 16 > /sys/class/gpio/unexport

#-----------------------------------------------------------------------------
# export
#
echo 29 > /sys/class/gpio/export
echo 59 > /sys/class/gpio/export
echo 58 > /sys/class/gpio/export
echo 35 > /sys/class/gpio/export
echo 52 > /sys/class/gpio/export
echo 92 > /sys/class/gpio/export



#-----------------------------------------------------------------------------
# Set direction = out
#
echo out > /sys/class/gpio/gpio29/direction
echo out > /sys/class/gpio/gpio59/direction
echo out > /sys/class/gpio/gpio58/direction
echo out > /sys/class/gpio/gpio35/direction
echo out > /sys/class/gpio/gpio52/direction
echo out > /sys/class/gpio/gpio92/direction

#-----------------------------------------------------------------------------
# Set active_low = 0 (false)
#
echo 0 > /sys/class/gpio/gpio29/active_low
echo 0 > /sys/class/gpio/gpio59/active_low
echo 0 > /sys/class/gpio/gpio58/active_low
echo 0 > /sys/class/gpio/gpio35/active_low
echo 0 > /sys/class/gpio/gpio52/active_low
echo 0 > /sys/class/gpio/gpio92/active_low

#-----------------------------------------------------------------------------
# Set edges = none if needed
#
# echo none > /sys/class/gpio/gpio4/edge
#-----------------------------------------------------------------------------

# Set pullups if needed
#
# raspi-gpio set 4 pu
# raspi-gpio set 11 dl
# raspi-gpio set 12 dl
#-----------------------------------------------------------------------------

- Save

- Make the file executable

chmod +x ~/domoticz/sysfs.sh

- Two options (many in fact)

1- Execute this script in the rc.local file:

~$sudo nano /etc/rc.local

- Add at the end of the script and before exit 0 this line

/home/domoticz/sysfs.sh

exit 0

2- Modify /etc/systemd/system/domoticz.service (better):

- Add the line : ExecStartPre=/home/domoticz/sysfs.sh before starting Domoticz

~$sudo nano /etc/systemd/system/domoticz.service

[Unit]

      Description=domoticz_service

      After=network-online.target

#      User=dietpi

#Kill rtl_433 (domoticz cant start if it's already started)

      ExecStartPre=-/usr/bin/killall -q rtl_433

#      ExecStartPre=/usr/bin/install -d -m 0700 -o pi5 -g PI5 /var/run/domoticz

      ExecStartPre=setcap 'cap_net_bind_service=+ep' /home/pi5/dev-domoticz/domoticz

      ExecStartPre=/home/domoticz/sysfs.sh

      

#Start domoticz

      ExecStart=/home/pi5/dev-domoticz/domoticz -www 80 -sslwww 0 -pidfile /var/run/domoticz/domoticz.pid

      Restart=on-failure

      RestartSec=1m

      #StandardOutput=null

[Install]

      WantedBy=multi-user.target

- Reboot

- Verify GPIO exports

~$sudo gpio exports

You should receive something like that:

GPIO Pins exported:

   0(29): out  1  none

   0(35): out  1  none

   0(52): out  1  none

   0(58): out  1  none

   0(59): out  1  none

In Domoticz -> 

    Setup -> 

        Hardware -> 

            Add New hardware of the type ‘Generic sysfs GPIO’.

        Then add new devices from unused in "Generic GPIO" (the name you give to your new hardware)

Don't forget to add those devices to your user !

Orange Pi 5 - Transfert System and boot ... EASY

From this thread : https://forum.armbian.com/topic/27048-not-booting-to-system-on-nvme/

Thanx to robnielsen

Deleted partition on NVMe (if needed)

gdisk /dev/nvme0n1

 

d

1

d

Copied SD card to NVMD

cat /dev/mmcblk1 > /dev/nvme0n1

Could take some time 

Powered off the Orange Pi 5, removed the SD card and then powered it back on and it booted from the NVMe. 

Then resized the filesystem

 /usr/lib/armbian/armbian-resize-filesystem start

 

Now I have some thing like:

$ df -H

OrangePi 3 LTS + USB DAC + MPD (from sources) + Resampling and Equalizer

 I've buy this DAC :

A CMEDIA CM6631A

HIFI CM6631A DAC Board USB Digital interface 32 / 24Bit 192k USB To I2S/SPDIF Coaxial Output Audio Decoder Analog Converter

Note : This DAC is a little noisy when using sampling frequencies above 48000 Hz, ultimately I do not recommend it. 😒

Compiling MPD from git (version 0.24) optional and not verified ! 

~#nano buildmpd.sh

#ALL AS ROOT

sudo su

cd ~

#Stop current MPD then remove

mpd --kill

Mean that your DAC is linked to :

• "card 1" mean hw 1
• "Subdevices: 1/1" mean only one device
• "Subdevice #0: subdevice #0" mean that this only device is the device 0

Trying the DAC

~#aplay -D hw:1,0 test.wav

If you have well-connected the DAC to an amplifier, you should hear the test.wav sound file.

Trying all devices ...

1. On board sound chip [allwinner,ac200-codec] :
• ~#aplay -D hw:0,0 test.wav
• Or by using the name:
• ~#aplay -D CARD=allwinnerac200c,DEV=0 test.wav
2. The DAC [USB2.0 High-Speed True HD Audio]
• ~#aplay -D hw:1,0 test.wav
• Or by using the name:
• ~#aplay -D CARD=Audio,DEV=0 test.wav
3. HDMI screen speakers [sun9i-hdmi]
• ~#aplay -D hw:2,0 test.wav

sudo apt-get install gcc g++ make git

Install and compile 433Utils :

git clone --recursive https://github.com/ninjablocks/433Utils.git 

cd 433Utils/RPi_utils 

make all

sudo ./RFSniffer

... Then press the corresponding buttons on the remote control. The code received is then displayed (for me, it is 5510417 for on and 5510420 for off). 

After reading the code, you can also remove the 433Mhz receiver if you mind.

sudo nano control.cpp

Put in it :

#include "../rc-switch/RCSwitch.h"

#include <stdlib.h>
#include <stdio.h>

int main(int argc, char *argv[]) {
int PIN = 0; // cf. wiring Pi pinout
int codeSocketDon = 5510417;
int codeSocketDoff = 5510420;

if (wiringPiSetup() == -1) return 1;

RCSwitch mySwitch = RCSwitch();
mySwitch.enableTransmit(PIN);

if (atoi(argv[1]) == 1) { // you can set your own conditions here
    mySwitch.send(codeSocketDon, 24);
} else {
    mySwitch.send(codeSocketDoff, 24);
}
return 0;
}

Then compile :

g++ -DRPI ../rc-switch/RCSwitch.cpp control.cpp -o control -lwiringPi

Turn ON :

sudo ./control 1

Turn OFF :

sudo ./control 0
