RHD:Features

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)
  • Easy plug-in updates using shared libraries
