ECUSB_Device_Init
The ECUSB_Device_Init function configures and initialises a new USB device.
ECUSB_ErrorCode ECUSB_Device_Init(
struct ECUSB_Device *pDevice,
struct ECUSB_Device_Configuration *pConfiguration
);
struct ECUSB_Device *pDevice,
struct ECUSB_Device_Configuration *pConfiguration
);
Parameters
pDevice
A pointer to a struct ECUSB_Device. This struct holds internal data for the USB Device. ESUSB_Device_Init will clear and initialize the struct.
pConfiguration
A pointer to a struct ECUSB_Device_Configuration. This struct needs to be created by the user, cleared and the necessary values needs to be filled in.
See description of struct ECUSB_Device_Configuration for a reference of the fields in this struct.
Return value
Returns one of the ECUSB error codes (ECUSB_SUCCESS on success)
Example Code
// Initialize the USB Device
struct ECUSB_Device_Configuration deviceConfiguration;
memset(&deviceConfiguration, 0, sizeof(deviceConfiguration));
deviceConfiguration.m_wVendorID = 0x2351;
deviceConfiguration.m_wProductID = 0x0200;
deviceConfiguration.m_wDeviceReleaseMajor = 0;
deviceConfiguration.m_wDeviceReleaseMinor = 1;
deviceConfiguration.m_wPowerConsumption = 100;
deviceConfiguration.m_bSelfPowered = FALSE;
deviceConfiguration.m_szManufacturer = "EmbCode.com";
deviceConfiguration.m_szProductDescription = "EmbCode.com USB Packet Sample Device";
deviceConfiguration.m_dwSerialNumber = 0x1234ABCD;
printf("Calling ECUSB_Device_Init()...");
err = ECUSB_Device_Init(&myUsbDevice.m_device, &deviceConfiguration);
if(err != ECUSB_SUCCESS)
halt("ECUSB_Device_Init failed", err);
printf("ok!\r\n");
