I just watched some pretty amazing videos of Adafruit webide using python remotely to program a Rasberry Pi. Take a look at these four videos in Youtube playlist: https://www.youtube.com/watch?v=8NoiBBgaKCI&list=PL-LlPBnLDbkXlexNd2Vq8ipI_Y9fh_byi Now that got me thinking that we can use Udoo & node.js to manipulate GPIO etc..., Rasberry Pi & Udoo both run Linux, both run Python, so can this be installed on another single board computer like the Udoo. Then I found another Youtube video, showing setting up the Adafruit webide on Beaglebone Black: https://www.youtube.com/watch?v=MwQGXAlq3Cc If it can be installed on other 'single board computers', like Beaglebone Black, why can't we have something for Udoo? So even though I knew it would not work, I though I would try and see how far I could get. Here are Adafruit's instructions for getting setup on Rasberry Pi: Code: sudo apt-get update && sudo apt-get -y install build-essential nodejs nodejs-legacy npm redis-server git git clone git://github.com/adafruit/Adafruit-WebIDE.git cd Adafruit-WebIDE mkdir tmp npm config set tmp tmp npm install editor config/config.js (change port 80 to your port of choice) nodejs server.js Well I had to try a different way: Code: sudo su echo "deb http://ftp.us.debian.org/debian wheezy-backports main" >> /etc/apt/sources.list apt-get update sudo apt-get -y install build-essential nodejs nodejs-legacy npm redis-server git curl --insecure https://www.npmjs.org/install.sh | bash git clone git://github.com/adafruit/Adafruit-WebIDE.git cd Adafruit-WebIDE mkdir tmp npm config set tmp tmp npm install editor config/config.js (change port 80 to your port of choice) nodejs server.js I had errors at the end of the npm install todo with gnu, so a bit of googling blindly: Code: sudo apt-get install python g++ make checkinstall Now I still can't get node.js to run, and even if I could, Adafruit's webide would probably need to be changed to run python code that could access the Udoo GPIO etc... Now I I can see how good it would be to be able to program the udoo using python, over a local network, I think it would be worth it for anyone with more experience than me to take a look to see if it would be possible. I remember their were some other guys with node.js working on Udoo, So please take a look
Re: can Adafruit Webide install on udoo, using node.js & pyt How the GPIO's are accessed on the UDOO is pretty different than on the BBB or RPi. At a minimum that part would need to be modified to work.
Re: can Adafruit Webide install on udoo, using node.js & pyt Can you expand on this, please? If you have any examples showing the differences, it would be great starting point
Re: can Adafruit Webide install on udoo, using node.js & pyt If you look at the Raspberry documentation on how to control the gpio pin using bash . Code: #!/bin/sh # GPIO numbers should be from this list # 0, 1, 4, 7, 8, 9, 10, 11, 14, 15, 17, 18, 21, 22, 23, 24, 25 # Note that the GPIO numbers that you program here refer to the pins # of the BCM2835 and *not* the numbers on the pin header. # So, if you want to activate GPIO7 on the header you should be # using GPIO4 in this script. Likewise if you want to activate GPIO0 # on the header you should be using GPIO17 here. # Set up GPIO 4 and set to output echo "4" > /sys/class/gpio/export echo "out" > /sys/class/gpio/gpio4/direction # Set up GPIO 7 and set to input echo "7" > /sys/class/gpio/export echo "in" > /sys/class/gpio/gpio7/direction # Write output echo "1" > /sys/class/gpio/gpio4/value # Read from input cat /sys/class/gpio/gpio7/value # Clean up echo "4" > /sys/class/gpio/unexport echo "7" > /sys/class/gpio/unexport Sorry , but using the kernel sys/class/gpio method , doesn`t that look the same on the udoo ? eg page 28 on the manual Code: In the /sys/class/gpio/ folder there are other sub-folders, one for each manageable GPIO. Each sub-folder contains files that indicate: ● direction (in / out) ● value (0 / 1) To read a GPIO direction: cat /sys/class/gpio/gpioXX/direction In or Out output is now expected To change the pin direction: echo out > /sys/class/gpio/gpioXX/direction or echo in > /sys/class/gpio/gpioXX/direction
Re: can Adafruit Webide install on udoo, using node.js & pyt Wow, that is very similar Peter. I remember seeing a .sh file on marchdvd.com for remapping the GPIO pins: UDOO alias pins for Due numbering http://marchdvd.com/?p=149 That method gives us some flexibility in trying the squeeze it together, too I suppose. I wonder if the Adafruit webide uses a 'special' python, or library, or whether it is straight?
Re: can Adafruit Webide install on udoo, using node.js & pyt I guess the other method is direct access and change the cpu`s registers direct !!!! If they have gone that I guess it is locked to only one cpu , but don`t adafuilt say that it will also work on the beaglebone black ?.
Re: can Adafruit Webide install on udoo, using node.js & pyt Yes they have an install guide for the Beaglebone Black too. The link is here: http://learn.adafruit.com/webide/installation-on-beaglebone
Re: can Adafruit Webide install on udoo, using node.js & pyt It would be really benefical to all of us if someone from the Udoo team could take a look at the WebIDE source on github: https://github.com/adafruit/Adafruit-WebIDE/tree/alpha/scripts The install scripts are here
Re: can Adafruit Webide install on udoo, using node.js & pyt i know i have tried both the adafruit webide and also the cloud9 IDE that is used on the BBB, i was not able to get either to work, mostly node.js issues as you have seen. I have talked with the UDOO team about these things because i feel a web based IDE wither ala Adafruits WebIDE, Cloud9, or something similar would be a very nice step forward in advancing the usability of the UDOO. I know they felt the ideas were good also, so there might just be something in the future from them if the community doesn't make it work first (i dont speak for UDOO, so im not saying they are actually gonna do this, i really have no idea).. unfortunately its beyond my skill level to do so myself
