ZeroII Vector Antenna Analyzer

Short communication interfaces description. The ZeroII in measurement mode supports communication with the host controller via SPI, I2C, UART. I2C interface use 7-bit slave address 0x5B. The firmware is updated via the USB interface using the RigExpert Flash Tool utility.

Commands supported by SPI, I2C, and UART interfaces:
ZEROII_GET_STATUS (0x5A) – ask for the ZeroII status. (Except SPI – you can read the status after setting CS low without prompting).

Possible answers:

• ZEROII_STATUS_BUSY_USB (0x01) – the device is busy with a task for the USB interface; ZEROII_STATUS_BUSY_SPI (0x02) – the device is busy with a task for the SPI interface; ZEROII_STATUS_BUSY_I2C (0x03) – the device is busy with a task for the I2C interface;
• ZEROII_STATUS_BUSY_UART (0x04) – the device is busy with a task for the UART interface; ZEROII_STATUS_IDLE (0x05) – the device is idle, ready for new tasks;
• ZEROII_STATUS_READY (0x06) – measurement results are ready;
• ZEROII_STATUS_ERROR (0x07) – an error occurred while executing the task;

   • used for UART only (INV_CRC = CRC ^ 0xFF).
   • used for SPI and UART.
   • before receiving delayed response you need at least once ask for STATUS and get ZEROII_STATUS_READY. Until the measurement is completed, STATUS will correspond to ZEROII_STATUS_BUSY_x.
