When you use the port configuration table, a ‘0’ means that the port is disabled, a ‘-X’ (X being your port number) is configured for input and a ‘X’ (again, being your port number) is configured for an output. The app installer, though, allows you to configure individual module ports without writing any code.

You could, in theory not have on load any software and just use the app preloaded onto the Wixel, provided the last user of this project did not change it or mess it up. Here is the link to their on-line guide to load the app installer for your operating system (OS): Link
For our purposes, we will simply use their app installed and try out one of their apps, the “I/O Repeater App”. Pololu has written 9 general purpose apps that will suffice for most user activities but if none of those fit the need, their guides and forums can take you into creating your own apps that reside right ton their transceiver module. When you go to the user’s guide, you will find enough information to keep a genius busy for months. Transceivers usually come in pairs in order to form a link.
GITHUB XSCOPE GABOTRONICS CODE
software with dozens of dependencies and different code for each side of a transceiver system (code A for the laptop station controlling end and code B for the satellite controlled or slave end.) Pololu wisely uses the same code for both ends and has written it to automatically detect which end of the communication system it is: if it is plugged into USB, it is the control end if it is running on other power (like battery or our bread board power supply) it is the satellite or controlled end. If you and I had to write the code to do all of that it would add hundreds of lines of code to our projects and be extremely tedious…(we just want to send a few bits back and forth, right?) Fortunately, other gifted people at Pololu have capsulized the ‘hard stuff’ and given us a very versatile pair of modules that are easy to reconfigure to do most anything a Maker could dream up for a transceiver.Īutomatic Configuration of Controlling Node and Satellite Node(s) The Federal Communication Commission (FCC) demands that radio transceivers use such protocol so that the airwaves remain useful for everybody. They also transmit in packets, which are bundles of digital data that include a header stating who originated the communication, the intended target of that communication, how big the packet is and a checksum so if part of that transmission is missing at the distant end the receiving party requests that it be retransmitted until it gets it 100% right. This is part of their communication protocol. A ‘polite’ radio transceiver will listen for an open channel before it transmits and if 2 transmitters accidentally try to ‘talk’ at the same time, they institute a random delay so they do not endlessly try to both talk again at the same time. If 2 devices try to talk over the same channel frequency at the same time you get a data collision in which both transmissions are corrupted. There is a finite number of available radio channels and numerous devices trying to communicate.
Using radio transceivers to connect computers, microcontrollers and sensors or control nodes is anything but simple. USB type A plug to type mini-B plug cable If something is missing contact us at E-mail.) Kit Inventory (Always check to see that all of your parts are present.
