pimatic-gpio for Banana Pro

---

I would like to use the pimatic-gpio for hardware platform Banana Pro with following pin out after execution of the command “gpio readall”.

The commands to a relay module is working:

gpio mode 23 out
gpio write 23 0
gpio write 23 1

I tried to apply the following in config.json. It is not working.

{
  "id": "relay-1",
  "class": "GpioSwitch",
  "name": "wPi Relay1",
  "gpio": 23,
  "inverted": true,
  "defaultState": false
},

Even with changing 23 to 13 does not help. How to solve it?

@ErikC Please format your posts properly, see https://forum.pimatic.org/topic/1179/how-to-post-code-snippets-and-alike-on-the-forum.

As far as I know, the gpio utility is part of wiringPI which adheres to the wiringPI numbering scheme (wPi). However, pimatic-gpio is using the BCM numbering scheme. Try to use pin number 13.

I know about the format but the pin-mapping will not show correctly with back-ticks.

I see that the controlling number 23 in pimatic will result into:
| 16 | 0 | OUT | GPIO. 4 | 4 | 23 |
That is BCM pin 23 / wiringPi pin 4.

However the BCM pin 13 / wiringPi pin 23 will never change to output mode. So it is not controlable by pimatic-gpio.
| 13 | 23 | GPIO.23 | IN | 0 | 33 |

Why not?

I have some doubts here. Please use three back-ticks as advised. See first post which I have edited.

Are you sure? In your first post you said that gpio mode 23 out; gpio write 23 0; gpio write 23 1 is working fine. With pimatic-gpio, the GPIOSwitch will set the given gpio pin to output mode. Did you try the following?

{
  "id": "relay-1",
  "class": "GpioSwitch",
  "name": "wPi Relay1",
  "gpio": 13,
  "inverted": true,
  "defaultState": false
},

If this does not work it might be a portability issue of the underlying onoff library. As far as I can see neither wiringPi nor onoffofficially support the banana pi pro. What may help is to move to lover pin number which falls in to the range of GPIO ports available with Raspberry Pi R2.

Regarding wiringPi do you use the Lemaker port, i.e. wiringBP?

Update: Having reviewed the code of the onoff library I think it should also run on banana pi!

I have checked the following:

gpio write 23 0/1 OK, {…13…} not OK.
gpio write 25 0/1 OK, {…26…} not OK.
gpio write 4 0/1 OK, {…23…} OK.
gpio write 5 0/1 OK, {…24…} OK.

The last 2 are now applied for my Banana Pro system. Working with lower pin numbers seems the good solution.

Paths of wiringpi and gpio:

which gpio
/usr/local/bin/gpio

ls /usr/local/include

ds1302.h     maxdetect.h  mcp3002.h   piFace.h   sr595.h
gertboard.h  mcp23008.h   mcp3004.h   piGlow.h   wiringPi.h
lcd128x64.h  mcp23016.h   mcp3422.h   piNes.h    wiringPiI2C.h
lcd.h        mcp23017.h   mcp4802.h   sn3218.h   wiringPiSPI.h
max31855.h   mcp23s08.h   pcf8574.h   softPwm.h  wiringSerial.h

To which module will call the onoff library? wiringPi or gpio?

ok, generally it should also work with the higher GPIO pin numbers. The onoff library uses the GPIO sysfs interface which you can also easily use from the command line as described in the following howto:
