  @Tisham-Dhar Yeah, the de-assertion of the CS line complicates things.

  Regarding setting up the Toolchain, take a look at the instructions in our Build System ReadMe. It will likely take the least amount of time if you use the Docker method on a Linux system.

  @Maximilian-Gerhardt I was thinking to remove the jack and solder to the points. I didn't know about Ethernet ports having integrated transformers though. I found a close-up of the board and I see a transformer after, but it would be hard to know for sure without taking one apart.

  Assuming the transformer is on the board and not the port, would that work?

  Adafruit has a library at https://github.com/adafruit/Adafruit_FT6206_Library and I've done some things with I2C on the Omega2 at https://github.com/gamer-cndg/omega2-wii-classic-controller using https://docs.onion.io/omega2-docs/i2c-c-library.html. Combine those and you should be able to port the library.

  Double-check that you have RX and TX connected correctly - they're easy to get swapped, as the usual convention is to connect TX of one device to RX of another.

  Also, you can check that you're getting bits by cating /dev/ttyS1, or using a terminal program like minicom or screen.

  I haven't found the precise answer to my problem but I am happy I have the resources to sort it out myself now.

  The resource I have found especially helpful has been a tutorial by Steve here:
  "Using The Mosquitto_pub and Mosquitto_sub MQTT Client Tools- Examples"
  http://www.steves-internet-guide.com/mosquitto_pub-sub-clients/

  It has also been useful to practice simple queries against a MQTT test service here:
  https://iot.eclipse.org/getting-started/

  Hope that helps someone else

  Awesome tutorial and really cool idea! I am running into an issue though and thought maybe you would know how to help me out since you just did this. When I go to initialize my postgres db, it gives me this error:

  fixing permissions on existing directory /root/pgdata ... initdb: could not change permissions of directory
  "/root/pgdata": Operation not permitted
  pg_ctl: database system initialization failed

  I followed your instructions and did the chmod 777 /root/pgdata before initializing and it doesn't seem to be working. Does this make sense to you?

  I use 2 methods:

  ping my webserver run ifconfig to check for existence of apclio and local IP address

  from result of both I could tell if I needed to call wifimanager to restart. Since b17* it's been stable enough to reconnect itself so I no longer use this and I cache data until I am able to connect again using urllib2.

  Taking it to the next level:
  
  This is my travelling demo unit I am working on. I added a Pi driven touch screen to the mix to allow for operator interaction with mysql in the onion via the onion AP, access control granted via a nifty little serial fingerprint scanner (can run on either pi or onion), barcode scanner and a little "closed loop machine demo" which contains 2 servo's and a microswitch that I still need to complete. It's come a long way since the veroboard prototype days! :)

  ...ok, I figure it out (more or less):
  There's on open regressed issue on Mono project for this:
  https://github.com/mono/mono/issues/9951

  I had to switch back to 2018-04 branch on Mono to make it work.
  Compiled with openwrt-sdk-18.06.1-ramips-mt76x8_gcc-7.3.0_musl.Linux-x86_64.tar.xz

  Cheers!

  @James-Seigel I am based in South Africa and buy a lot of the new arrival chips and modules to play with from this company:

  https://www.robotics.org.za/YK-E1007

  I am not sure if Micro Robotics could ship internationally but sure they can help you locate a local supplier. I ordered one from banggood.com in china but it hasn't been delivered yet after 3 months of waiting

  Hi @Carlos-Sancho how do you control your OLED? do you use oled-exp or related python/c libraries or did you have to write your own program to communicate with the display?
