    Table 2: Low level message format - <HEADER> – Is always a byte with a value of 0xFE. - <CMD> - Defines the command group sent to the RASPIVend. - <SUBCMD> - Defines the specific subcommand of the command group.

  • Page 8: Hardware Overview

    CCTALK PERIPHERALS are protected, but will not work. The board also supplies the 5V/2A for Raspberry PI (or compatible). The system eliminates the separate 5V microUSB power supply for Raspberry PI. You will only need one power supply for the entire system.
  • Page 9 POWER, GPIO and serial port. This connector, also supplies the power for Raspberry PI. Used pins and functions can be find in the table below. Pins marked by green background are available for user applications and alos, the power and GND pins.

  • Page 10: Low Level Mode

    III. Low level mode To use this mode, your application must handle the following: a. GPIO pins of the Raspberry PI, needed to switch the multiplexers to the correct communication channel (to select the peripheral). b. Serial port of the Raspberry PI (/dev/ttyAMA0).
