RHD is developed as a flexible hardware abstraction layer framework, that could be used in any application where interaction between a high-level control program and hardware devices are needed in real-time.

The main philosophy of RHD is the idea of a distributed variable database, making all communication variable oriented. A plug-in structure makes it simple to write interfaces to new hardware.

Feature list

  • Soft and hard real-time operation possible
    • Linux or RTAI scheduling support
    • Fixed and accurate timebase
  • Two-way variable database
    • 32-bit signed database variables
    • Timestamps for all variable updated
  • TCP / IP Socket interface
    • Only one write-client accepted (first in, first access)
    • Theoretically up to 256 read-clients
    • Low communication overhead in protocol
  • Plug-in interface with a range of plugins avalible (see RHD:Plug-ins)
    • Fast and efficient development of interfaces for new hardware
    • Easy plug-in updates using shared libraries
