RaDeKL Radar API Programmer’s Guide 37

Example 1:

Read the value of the register at address 7 (REGISTER_DAC1).

ULONG status;

DWORD bytes_received;

RaDeKL_HANDLE handle;

BYTE cmd[5] = {CMD_READ, 0, REGISTER_DAC1, 1, CMD_TERM};

BYTE response [1024]; // Make this sufficiently large

// Assume we have an open radar with a valid handle

status = RaDeKL_SendCommand (handle, cmd, 5);

// Check status . . .

status = RaDeKL_ReceiveResponse (handle, response, 4, &bytes_received);

// Check status . . . and ensure that bytes_received == 4

printf (“The value at register DAC 1 is %d\n”, response[2]);

Example 2:

Issue a single detection request and read the range bins returned.

ULONG status;

DWORD bytes_received;

RaDeKL_HANDLE handle;

BYTE cmd[5] = {CMD_WRITE, 0, REGISTER_DETECT, DETECT_SINGLE, CMD_TERM};

BYTE response [1024]; // Make this sufficiently large

// Assume we have an open radar with a valid handle

status = RaDeKL_SendCommand (handle, cmd, 5);

// Check status . . .

status = RaDeKL_ReceiveResponse (handle, response, 260, &bytes_received);

// Check status . . . and ensure that cnt == 260 (number of range bins + 4)

// The range bin data is now in response[3] thru response [258].

// response [0], [1] and [2] contain 0xEA and response[259] 0xFF (terminator).
