Mysensors Gateway on OrangePi (Zero) (opi)

[Tag]

@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!!

root@OrangePI:~/marceloaqno-spidev#

i want build a gateway with orangepi one with channel 0 . what am i do ? thank you

[marceloaqno]

@Reza You need to run:

modprobe gpio-sunxi

so that /sys/class/gpio/export is created.

[marceloaqno]

@Tag Does the TMRh20 works in the way your radio is currently connected?

[Tag]

@marceloaqno
The library compiled, but unfortunately i cannot get the examples for linux working.
need to edit i.e. gettingstarted.cpp with the correct pin setting, have tried a lot, but either it says that the radio is not connected, and if used with incorrect settings it will not compile at all....

Maybe someone following this thread who has experince with this lib?
if there is any progress from my side will keep you posted...

[mihai.aldea]

If you used this wiring scheme:

nRF24L01 | Orange Pi
_________|________________
VCC      | VCC3V3-EXT
GND      | GND
CSN      | SPI0_CS0 (SPI-CE0)
CE       | PA7 (IO-7)
MOSI     | SPI0_MOSI (SPI-MOSI)
SCK      | SPI0_CLK (SPI-CLK)
MISO     | SPI0_MISO (SPI-MISO)

Then you should initialize the radio with:

RF24 radio(7,0);

Worked for me:

root@opi-pc-1:~/RF24-master/examples_linux# ./gettingstarted

[marceloaqno]

@mihai.aldea Could you try the repo I'm working on (https://github.com/marceloaqno/MySensors/tree/spidev marceloaqno-spidev) adding your settings to the examples_linux/mysgw.cpp?

#define MY_RF24_CE_PIN 7
#define MY_RF24_CS_PIN 0

[Tag]

@mihai.aldea

Hmmm.... checked the docs again and guess what. the 26 pin header on the OPI Zero has SPI1.... instead of SPI0

Expansion Port

The Orange Pi Zero has a 26-pin, 0.1" unpopulated connector with several low-speed interfaces.
2x13 Header
1	3.3V	           2	5V
3	TWI0_SDA / PA12	   4	5V
5	TWI0_SCK / PA11	   6	GND
7	PWM1 / PA06	       8	UART1_TX / PG06
9	GND	               10	UART1_RX / PG07
11	UART2_RX / PA01	   12	SIM_CLK/PA_EINT7 / PA07
13	UART2_TX / PA00	   14	GND
15	UART2_CTS / PA03   16	TWI1-SDA / PA19
17	3.3V	           18	TWI1-SCK / PA18
19	SPI1_MOSI / PA15   20	GND
21	SPI1_MISO / PA16   22	UART2_RTS / PA02
23	SPI1_CLK / PA14    24	SPI1_CS / PA13
25	GND	               26	SIM_DET/PA_EINT10 / PA10

From http://linux-sunxi.org/Xunlong_Orange_Pi_Zero
If i look at /dev I only see spi0, which is most probably used for the onboard flash...

root@orangepizero:/# ll /dev | grep -i spi
crw------- 1 root root    153,   0 Jan  8 11:12 spidev0.0

So now i need to figure out a way to get SPI1 up and running

@Tag Use this info:
http://linux-sunxi.org/Sunxi-tools
To export /boot/script.bin, edit the output file and enable SPI1, then compile it back and reboot your OPi with the SPI1 active.

If you haven't done this before, it's quite simple.

apt-get install sunxi-tools
cd ~
bin2fex /boot/script.bin > script.fex

Edit the script.fex file, find the [spi1] section and change spi_used = 0 to spi_used = 1. Save the file and exit.
Then

fex2bin script.fex > /boot/script.bin

Reboot, then you should have the SPI1 active.

[Reza]

@marceloaqno
i have error yet
orangepi is a good board. please work at this board and run mysensors gateway on this, i follow this topic when you can fix this on orange pi . thank you

[Tag]

@mihai.aldea

Yep already found it :) problem was the old version of the tools, it was not able to decompile the script.bin file...

[update]

• modified the script file,
• changed spi_used = 1
• compiled back and rebooted

just 1 device file in called spidev0.0 no new device files are created..... :(

dmesg output:

[    0.814287] sunxi_spi_chan_cfg()1376 - [spi-0] has no spi_regulator.
[    0.814316] sunxi_spi_chan_cfg()1376 - [spi-1] has no spi_regulator.
[    0.815569] spi spi0: master is unqueued, this is deprecated
[    0.816776] spi spi1: master is unqueued, this is deprecated

Thx, will keep you posted!

[marceloaqno]

@Reza Was /sys/class/gpio/export created after modprobe gpio-sunxi?

@mihai-aldea Could you send the complete make and configure output so I can check if your system is correctly detected?

@mihai.aldea I think you're not in the right branch, could you start from scratch like this:

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

[Reza]

@marceloaqno
i have not any folder "gpio" in class folder .
what am i do ? :(
can you create a new topic with all steps after full fix on orange pi ?
thank you. i follow this topic

[mihai.aldea]

@marceloaqno You were right, I wasn't using the correct branch. Your instructions though did not work for me

root@opi-pc-1:~# git clone https://github.com/marceloaqno/MySensors/tree/spidev marceloaqno-spidev
Cloning into 'marceloaqno-spidev'...
fatal: repository 'https://github.com/marceloaqno/MySensors/tree/spidev/' not found

Anyway, I found another way:

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

This time it compiled successfuly, but when I fired up mysgw all I got was:

mysgw: Starting gateway...
mysgw: Protocol version - 2.2.0-beta

with no other output.
Just to be sure we're on the same note, what is the wiring schematic I should use? When I first started to tinker with RF24 on OPi I found at least two wiring schematics.
For reference here's the gpio readall on my OPi PC:

Just a question the command "gpio readall" does that does show the actual status of the system, or is it just a fixed table that is printed on screen....

Look at mine:

It is the same... and shows 40 pins while the OPI Zero only has 26.......
There are some small differences between our tables in the naming column... so i guess it really reads the status / names of the pins.. Anyhow still strange that 40 pins are shown instead of 26 for the zero..

@marceloaqno: are you planning to create a pull request? also, like @Reza suggested i think it would be smart to gather all information somehwhere, unfortunately mysensors does not seem to have a wiki. can we write an article somehow? i could take care of that.

@mihai.aldea sorry about the github link mistake.

@pansen Yes, I will.

Is the orientation of the pins correct in the image?
