How to: banana pi BPI-M3 install BPI-WiringPi


(bpi team) #1

Download For BPI-M3.

git clone https://github.com/BPI-SINOVOIP/BPI-WiringPi.git -b BPI_M3

Installation:

cd BPI-WiringPi
chmod +x ./build
sudo ./build

test wiringPi is install success

gpio -v

gpio readall

create new : blink.c

#include <wiringPi.h>
int main(void)
{
  wiringPiSetup() ;
  pinMode (0, OUTPUT) ;
  for(;;) 
  {
    digitalWrite(0, HIGH) ; delay (500) ;
    digitalWrite(0,  LOW) ; delay (500) ;
  }
}

compile and run it:

gcc -Wall -o blink blink.c -lwiringPi

runing it:

sudo ./blink

How do i use the hardware PWM correctly? I already figured out that i have to use wiringPi Pin 7. I executed the following code:

gpio mode 7 pwm
gpio pwm-ms
gpio pwmr 128
gpio pwmc 6
gpio pwm 7 120

But i get the following error:

val pwmWrite 0 <= X <= 1024 Or you can set new range by yourself by pwmSetRange(range

The same error occured when i coded the same with the C library:

#include <wiringPi.h>

int main ()
{
  if (wiringPiSetup() == -1)
    return 1;
  pwmSetMode(PWM_MODE_MS);
  pinMode(7, PWM_OUTPUT);
  pwmSetRange(128);
  pwmSetClock(6);
  pwmWrite(7,120);
  return 0 ;
}

But i got the same error. I think there is still a bug. Please confirm or give any suggestions, what i’m doing wrong.


#3

Does anybody have an idea?


#4

Maybe the vendor you got hardware and software from? Think positive and stay calm! Maybe they need just another 2 months to ignore your question but then maybe they’re in the mood to look into. But I would suspect they give a shit as usual.

BTW: Do you have something below /sys/devices/platform/sunxi_pwm available? If not why do you expect that PWM should work?


#5

How to force m3 to allow exporting gpio? example: echo 7 > /sys/class/gpio/export -su: echo: write error: Invalid argument


(Daniel) #6

Hi, i Followed the instruction but become an error. Can anybody help me?


(BPI_Justin) #7

HI: please reference the document and provider error messages.

https://bananapi.gitbooks.io/bpi-m3/content/bpi-m3_wiringpi.html.


(Daniel) #8

Error message is in the Picture of my last post


(BPI_Justin) #9

you can run “gpio readall” commnad?


(Daniel) #10

Yes, i can run the command. But become an error Message

Unable to determine Hardware version. I see: Hardware : sun8i


(BPI_Justin) #11

HI: Please reference it


(Daniel) #12

This not help me, I followed the instructions above but output the same error message .

If you are unable to help me, say it and let other try to help.

First you must remove WiringPi: sudo apt-get remove wiringpi .
Then compile new Bpi-wiringpi.


(Daniel) #14

Thanks, It works.

Best regards

Hello, I NEED to run WiringPi as normal user since I will be implementing it with ROS. I followed that guide:

but I can’t find anywhere the gpio files that should be under /sys/class/gpio, where are them?

@BPI_Justin I have a similar problem as @Osa_Kozak

However i am using: Ubuntu 16.04 mate… Release Date: 2017-07-20

When i follow your tutorial explicitly i get the following error:

pi@bpi-iot-ros-ai:~$ cd BPI-WiringPi
pi@bpi-iot-ros-ai:~/BPI-WiringPi$ chmod +x ./build
pi@bpi-iot-ros-ai:~/BPI-WiringPi$ sudo ./build

However when i change: git clone https://github.com/BPI-SINOVOIP/BPI-WiringPi.git -b BPI_M3

To: git clone https://github.com/BPI-SINOVOIP/BPI-WiringPi2.git

It installs ok. but there is no test file in the M3_test folder

What is wrong with the: git clone https://github.com/BPI-SINOVOIP/BPI-WiringPi.git -b BPI_M3 ???

newest wiringpi:


(fred) #19

Your new version lead to the same message error describe by @Shadow3561

Unable to determine hardware version. I see: Hardware : sun8i

  • expecting BCM2708, BCM2709, BCM2709. If this is a genuine Raspberry Pi then please report this to projects@drogon.net. If this is not a Raspberry Pi then you are on your own as wiringpi is designed to support the Raspberry Pi ONLY

So, conclusion, even if you provide something from another developer (who seems to be not happy of that)… can you please give the correct patch to implement the gpio.

Thank you

WiringPi broke my kernel but WiringPi2 worked without any problems thanks @sinovoip great work!
