  • Arduino - Windows communication: Using C#

    Hi all! One of my past blog entries described in detail my adventures in designing and building the EPROM Reader. When discussing the Windows software I made a brief mention of a sub project that provided a prototype of the communication subsystem within…

  • Problem in coding for RC4 security in arduino communication

    Hello: I am trying to implement RC4 encryption in MCU [i.e. Arduino UNO]. I want to set up 2 Xbee [radio] +2 Arduino for a small network where 1 Xbee+1 Arduino will work as transmitter [encrypts the data] and another set of Xbee +Arduino will receive…

  • Parsing integer strings?

    I need help with parsing a string of integers sent from another Arduino. The values will be like this 1, 0, 1234, 1234, 1 is a Boolean 0 is a Boolean 1234 are pot values I would like for it to go to variables Vpot is first pot value Hpot is second pot…

  • NexGen Flight Simulator: Software Overview: Nav IOP

    DEPRECATED: 1/23/2000 DESIGN GOALS: I have talked about the IOP before so I will review the design: The IOP can control multiple CDUs (dumb terminals) via an Ardunio's USB. The IOP listens to the NavGroup UDP broadcast for present position, etc. The IOP…

  • Flight Simulator 101 or back to college - part 5.2: Protocols

    Ok so here is a map of our simulator: A small network. The CDU. The IO Processor #1. The Simulation Processor. A block diagram of the arduino and what's it doing. Interfaces to the display controllers via I 2 C. Ps2 keyboard Interface. The switches via…

  • NexGen RSS Continued.. The Protocols

    Protocols again? Are we ever done talking about protocols? No not really. And BTW this is really RSS version 2! RSS v1 can be found on my other wordpress blog . This version eliminates most of special hardware and its bus and chassis. Most radios heads…

  • NexGen RSS - Radio SubSystem

    Ok, so what the heck is an RSS ? The RSS is a central location in the simulation for all of the radio stuff. The Analysis NexGen can handle any type of radio interface, but not limited to ARINC-410, ARINC-429 , MIL-STD-1553 , or anything else you…

  • Hacking a Collins 614L-8 ADF Control Head, Part 2

    The Plan Continued. We need to pick an embedded CPU. The requirements are: It must handle all of the GPIO (see part 1 for the I/O Table), or about 20 pins. It needs a USB interface for a data link to talk to the host. It needs to generate…
