Requirements: wiringpi
## Usage Speedmanager ##

    ~$ ./speedmanager -h
    Speedmanager for Raspberry Pi by Philipp Hinz - Build number 921 short GUID 0x3c0
    Usage: /opt/hinz-ba-can/code/Pi code/Debug/speedmanager [-hvVteilfads] [-r ohms]
            -h              Prints this help
            -v              Sets verbose output, can be used multiple times
            -r ohms         Sets the start resistance of the digital potentiometer
            -V              Prints only the version and exits
            -t              Terminates the CAN Bus with a connected DiPoti
            -e              Echoes all incoming CAN messages (Debugging)
            -i              Increases the Wiper of the DigiPot every second
            -l              Sets the MCP2515 to listen only mode on shutdown
            -f              Forces a speedtest after startup
            -s              Suppress a speedtest in case of errors
            -a              Add new nodes if not known in file nodes
            -d              Prints a timestamp in front of every message
    Listening to the following signals:
            SIGUSR1(10)     Prints monitor data of all nodes
            SIGHUP(1)       Runs a speedtest starting at default speed

Debug levels:
 1. Basic debugging, process informations
 2. CAN messages
 3. CAN speedchanges
 4. SQL querys
 5. CAN error states
 6. SPI communication
 
## Usage canspeed ##
This helper programm outputs the register configuration for different CAN controllers. So far supported: MCP2510/15 and AT90CAN.

    ~$ ./canspeed -h
	Usage: /opt/hinz-ba-can/code/Pi code/Debug/canspeed -c Clockspeed -t Type [-ro] [-b Baudrate] [-q #TQ]
			-h              Prints this help
			-c              Cockspeed in MHz, 16 MHz recommended
			-t              CAN controller type (1 - MCP2510/15, 2 - AT90CAN)
			-b              Calculate settings for a single baudrate in bit/s
			-q              Number of TQ per bit, default is 16
			-r              Output register settings (use without -o)
			-o              Output the constant definitions for the controller
	Example: ./canspeed -c 16 -t 1 -o

## Sourcecode ##
The program source is distributed between multiple files. Please refer to the documentation of the files for their content.
The project is written in C++11 in Ecplise under a cross compiler environment. See Makefiles in Debug/ for cross compiler makefiles. See Release/ for Makefiles for Raspberry Pi.

For compiling on Raspberry Pi 2:

	cd Release
	make all -j 4

(-j 4 runs make with up to 4 threads)
