Software Defined DMA and uartRouter

This university project contains an implementation for a router on a discovery board. It can receive messages over UART connections, assign them to their destination connection/device and sends them out over the according UART connection.

Structure

boardConfigs	Configuration files for the discovery boards. Useful to flash and debug multiple devices in parallel in Clion.
src/clients/	Demo Logic for two discovery board clients which send messages and receive messages to and from the router. Not required for the router to work!
src/connection.*	UART connection which can receive and send messages.
src/router.*	Router, which assigns latest received messages to its destination UART and commands to send them.
misc/diagramm.odp	Depics the router structure graphically.
misc/gtkterms.sh	Opens gtkterm debug connections for the demo setup (two clients, one router).

Setup

• Make sure you pull the RODOS submodule
• If you want to debug the setup, install gtkterm, OpenOCD and GDB (or equivalent software)
• If you want to introduce, remove or change discoveryboards/client devices
  • Adjust the board configuration files accordingly to your own devices.
  • Adjust UART connections in router.cpp
  • Adjust CMakeLists.txt, to build an application for each device
  • Insert the topic assignments in router.cpp/initTopics()(defines which connection/device receives messages from other devices)
