Erika Source code

erika-1.3.1.zip ERIKA Educational 1.3

The current version of E.R.I.K.A. integrates:

  • Libraries:
    • Cyclical Asynchronous Buffers (CABs)
    • Blocking semaphores
    • Alarms
    • C++ support library (no exceptions, no rtti)
  • Kernels:
    • Fixed Priority with Preemption Thresholds
  • Hardware Abstraction Layers:
    • Hitachi H8 - Lego Mindstorm RCX (mono and multi stack)
      • support motor output in fixed mode and with a PWM at 1KHz :-)
      • support for common sensors (touch, rotation, light)
      • fixed point mathematics
      • infrared sensors (single and multi-bytes transfers)
      • serial I/O (experimental)
      • Gcc3 preliminary support
    • Wireless Ring-based communications
    • Matlab support

firmdl3 To upload an Erika Educational application on a Lego RCX we used the firmdl3 program distributed under the Mozilla Public License by Kekoa Proudfoot.
Kekoa's firmdl3 home This is the original Kekoa Proudfoot's web page. Look here for updates to the firmdl3 software.
send.c This small utility can be used to send single numbers to the vehicles in erika/tests/h8/newvehicle/*
sendbuf.c This small utility can be used to send a string of numbers to the ERIKA Applications.
rcv.c This utility is a modified version of send.c written by Michele Cirinei that READS from the IR tower and prints on the console all the received bytes (in hex format). With a little trick, (a byte is written and read just after that) the tower stays on without going off after 1 sec as usual. We actually do not know if that may cause other problems to the tower.
