  Could anyone here provide me with some pointers on how I might use Blynk with Onion Omega devices? I have the app installed on my iPhone, and I've already obtained an Auth token. However, I can't seem to locate any clear instructions on how to interface with the Omega. Basically, I'm just looking to set up some buttons that trigger the execution of scripts. I used to be able to do this with the Onion Cloud, but as we all know .. that's no longer in existence.

  On a related note .. has anyone here had any success with using nGrok to access their Omega from the internet? If so, .. is it something that you have to install on the Omega? If so, how?

  Thanks,

  @Tisham-Dhar I've gone ahead and implemented a working half-duplex transmission function! Version 4.0.1 of python-spidev features a new xfer3 function.

  Getting the Latest Version of python-spidev

  If you don't have it installed already:

  opkg update opkg install python-light python-spidev

  If you have it installed, you'll need to upgrade:

  opkg update opkg upgrade python-spidev To use the new function: values = spi.xfer3([<list of bytes to write>], <number of bytes to read>)

  This will write all of the bytes from the list in the first argument and will then immediately read the number of bytes specified by the second argument.

  The function will return a list of the bytes that were read.

  An Example

  Instead of using spi.xfer([0x80,0xD9,0x00,0x00])

  Try values = spi.xfer3([0x80,0xD9], 2)

  More Details

  More details can be found in our python-spidev github repo readme

  Let me know how it goes!

  FRDM KL-25Z is an awesome little board based on the MBED platform. And then, old school, home-brewed 8031/51 based boards, which, because of the ease with which you can access every part of the hardware, still kicks arse for some applications because there is no OS that gets in the way.
