Mysensors Gateway on OrangePi (Zero) (opi)

[mihai.aldea]

@Tag Just to make it clear, do you want to connect the RF24 radio directly on the OPi's GPIO pins? Or do you want to connect it first to an Arduino and then to the OPi?
I haven't used the mysgw because so far I only played with EasyIoT (directly attached RF24 to RPi GPIO - doesn't work on OPi) and MyController (using an Arduino connected to the OPi's serial port).
Since MySensors is open source you can definitely change the pin numbers to match the OPI's Sunxi pin numbering. I don't have a setup in place right now to point you in the exact direction but will cook one tomorrow and get back with the details.
Meanwhile you can burn the GatewaySerial sketch on your Arduino and either use /bin/mysgw or:

apt-get -y update
apt-get -y install minicom
minicom -D /dev/ttyUSB0

It's likely that the minicom will scramble the text on your screen but you can:

Ctrl+Z
O
Screen and Keyboard
T
Esc
Save setup as df1

Close the minicom window then open it again and all should be fine.

Hi!, my idea is to have the NRF24 radio directly attached to the GPIO header on the OPI, (got this already working on my RPI system). So the idea is to run mysgw on the OPI system.
(already got an extensive sensor network running with multiple arduinos and Mycontroller on thae RPI) On the RPI i had the arduino GW attached to USB and the NRF24 directly attached at the GPIO header at the same time, MyController saw 2 gateways :) )

The other option like you already mentioned is to attach the arduino using USB read from /dev/ttyUSB0. I see this as a last resort only if mysgw will never run on the OPI zero.

I read on the OPI website that the 26 pin header from the OPI is directly compatible with the RPI, however other sources of information tell me differently. So if you want to help out with the pin numbering this is greatly appreciated!

but again mysgw on the OPI with the radio on the GPIO header would be great!!

At this moment we try to build/compile mysgw on the OPI board, however that fails at the SPI part.

Thanks!

@hausinger The problem you are having with your serial gateway (./configure --my-gateway=serial --my-serial-port=/dev/ttyUSB0 --my-serial-baudrate=115200) may be related to this bug:

@Tag I made the test setup and retraced my steps from the previous experiment. While the TMRh20 is working, the problem indeed lies with the ** mysgw** compilation. I'm getting the same error.
After spending quite some time trying to mitigate the errors I hit a wall and I concluded that the problem is not the different pin numbering but the mysgw source code. I believe the problem is the lack of support for this architecture and with MySensors being so complex and my C++ skills so average, I'm afraid I can't help.
However, if someone can mitigate the source code to successfully compile, the radio should be initialized with:
RF24 radio(7, 0);
7 - CE pin
0 - CS pin
More details here: https://github.com/TMRh20/RF24/issues/257

Thanks for the confirmation!!, now lets hope that mysgw, will be fixed/ported to the OPI boards soon!
would be great to expand the number of systems it will run on..

@Tag
Could you setup my sensors gateway on orange pi one? if you can please help me to build this . thank you

[Tag]

@Reza

Unfortunately the mysgw software does not run native on the OPI systems at this moment.The only option today is to add an arduino to the USB port running i.e the serial gateway sketch (if you do not want to use the USB port, an other option would be using an UART trough the GPIO header, you data will show up on i.e. /dev/ttyS1 if UART 1 is used)

step 2 will be to install controller software.
(i tested MyController on the OPI and that works like a charm, and looks pretty cool!)

See this link on how to build a serial gateway on the arduino. Using this setup you can follow the RaspberryPI tutorials.

Hopefully mysgw will run soon on the OrangePI systems! think this is work in progress......

[marceloaqno]

I'm trying to add support for Orange Pi to MySensors, this is the work-in-progress repository:
https://github.com/marceloaqno/MySensors/tree/spidev

It would be great if someone could test and submit results from the configure and make commands:

git clone https://github.com/marceloaqno/MySensors marceloaqno-spidev
cd marceloaqno-spidev
git checkout spidev
./configure
make

Just hooked up a radio to the GPIO header. (used this link for the model 1 RPI https://www.mysensors.org/build/raspberry and attached the interrupt pin also to pin 15)

This is the result i get
root@orangepizero:~/marceloaqno-spidev/bin# mysgw
mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0-beta
mysgw: Could not open /sys/class/gpio/gpio10/direction

@Tag Great! The mapping of the physical GPIO number in OrangePi is not ready yet, so you need to figure out the correct value for the CE and CSN pins by adding this to the examples_linux/mysgw.cpp or MyConfig.h

#define MY_RF24_CE_PIN X
#define MY_RF24_CS_PIN Y

This is the best pinout image I've found that could help:
https://oshlab.com/orange-pi-zero-pinout/

This may also give you some hint:

cat /sys/kernel/debug/gpio

[marceloaqno]

@Tag Maybe this one can help too:
http://orange314.com/WiringOP

[marceloaqno]

@Tag also, please don't set the interrupt pin for now.

[marceloaqno]

@Tag I found more information on the wiki page about the gpio pins:
http://linux-sunxi.org/GPIO

It seems that there is a calculation to be made to know which number to use :scream:

[Tag]

@marceloaqno

Hi!!, many thanks for the info!! really helpful!
Made some progress. first I created this table based on this page: http://linux-sunxi.org/GPIO

Pin - Num - Name - Calculated value A=1 ((1-1)*32 + Pin)
CE / 22 / PA02 / 2
SCK / 23 / PA14 / 14
MISO / 21 / PA16 / 16
CSN / 24 / PA13 / 13
MOSI / 19 / PA15 / 15

Now it is important that you know which kernel is used on your systems the 4.x architecture is different compared to the 3.x arch...

If the 4.x kernel is used you need to use the calculated value for the GPIO pin numbering, i could not test that since I am using the 3.x kernel, so this is what i did:

1. load the GPIO kernel module:

modprobe gpio-sunxi

2. Create the GPIO device files since these were not available on my system by default.

for A in 1 2 3 4 5 6 7 8 9 10 11 12; do echo "$A" > /sys/class/gpio/export ; done

This created the following entries in /sys/class/gpio

root@orangepizero:~/marceloaqno-spidev/bin# ls -l /sys/class/gpio

Modified mysgw.cpp to use:

#define MY_RF24_CE_PIN 2
#define MY_RF24_CS_PIN 13

And did a clean build:

make clean
./configure
make

Now some thing has changed! :)

@marceloaqno
Did some testing,

Setup the GPIO pins:

modprobe gpio-sunxi

for A in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 
do echo "$A" > /sys/class/gpio/export
done

(The device files that are created by the commands above do not survive a reboot, so remember to execute the above commands after each reboot!)

Hooked up an led between ground and i.e. pin 22, this pin is linked to GPIO2

Then:

echo out > /sys/class/gpio/gpio2/direction
echo 1 > /sys/class/gpio/gpio2/value
echo 0 > /sys/class/gpio/gpio2/value

And eureka!! Led went on and off :D

Did this for all GPIO ports used by mysgw, below is the verified pin / GPIO table

Pin#  -  GPIO / NRF24 
22 - GPIO2   / CE
23 - GPIO14  / SCK
21 - GPIO16  / MISO
24 - GPIO13  / CSN
19 - GPIO15  / MOSI

Tested all pins and led went on and off on all

How i connected the radio: https://www.mysensors.org/build/raspberry (see the Pi1 part)
How to setup GPIO: http://linux-sunxi.org/GPIO (3.x kernel part, and added pin 13/14/15/16)
Pinout for the OPI Zero: https://i1.wp.com/oshlab.com/wp-content/uploads/2016/11/Orange-Pi-Zero-Pinout-banner2.jpg?fit=1200%2C628&ssl=1 (carefully look at the pin numbering!)

Maybe it is usefull, I rebuild mysgw with NRF24 radio debugging enabled, this is the output I get:

Are you sure this is correct?
The formula is: (position of letter in alphabet - 1) * 32 + pin number
For PA02 for instance the correct value is:
PA02 = (1 - 1) * 32 + 02 = 2

Actually you don't need to use the formula at all with the PA ports, all you have to do is use the trailing number.

@mihai.aldea

You are right, took the letter P, which is 16.... but is should have been A.... (for the 4.x kernel)
Updated the table!,

Thx!!
