HadCon Multipurpose Controls - Device Classes

Device Classes supported by the API

CAN bus

• Acting as a CAN bus master, using connector JCAN1
• up-to-now:
  • only 11-Bit-Identifier, "Base frame format" (CAN 2.0A)
  • 29-Bit-Identifier, "Extended frame format" (CAN 2.0B) extension on request
• Sending, receiving, subscription to channels defined by ID and optionally by a mask (default 0)

1-wire

• access to up to 8 individual 1-wire chains/buses connected to connector JDINOUT2, pins 1-8
• global commands
  • list all devices
  • determine parasitic devices
  • TODO:
    • missing, not yet implemented, but prepared
      • 1-wire atomic commands
• family specific commands
  • temperature sensor
  • adc
  • switches (1/2/8(TODO))

Internal ADC

• read values

Threshold Relay

• switching of output pin depending on input of ADC
• configurable input
  • TODO: add documentation

I²C - a.k.a. Two Wire Bus

• not yet implemented in version 3.1 but in progress, comes with 4.0
• direct access only to internal devices foreseen (DAC)
  • but a bit of soldering may widen its horizon.

DACs

• 2 times 4 channels DAC,
• output connector JDAC1 and partly JPS

Internals of microcontroller

• help, all and command specific
• debugging
  • increasing verbosity,
  • mask available
• status (show)
  • memory status (initially unused, unused, free)
  • available predefined error statements
• direct register access read/write
• JTAG enable/disable (handle with care)
