TE_USB_FX2_CyAPI (C++) APIs and TE_USB_FX2_CyUSB (.NET) API do not have the same signature although they are very similar. The signature of the pure extern C code library version of TE_USB_FX2_CyAPI APIs available for developers (codename: simplified TE_USB_FX2_CyAPI APIs) is slightly different from the two signatures above.
TE_USB_FX2_CyUSB (.NET) API is intrinsically cleaner than TE_USB_FX2_CyAPI (C++) APIs because CyUSB.dll is intrinsically cleaner than CyAPI.lib.
Please note that CCyUSBDevice Cypress class in the Cypress CyAPI C++ API is actually the list of all USB devices currently served by a Cypress USB driver derivative (e.g. Cypress generic USB device or Trenz Electronic USB FX2 device). For ease of understanding and convenience, Trenz Electronic named the corresponding variable as USBdevList.
API | Cypress class name | TE USB FX2 variable name |
|---|---|---|
C++ API | CCyUSBDevice | USBdevList |
.NET API | USBDeviceList | USBdevList |
Table: device list.
API | Cypress class name | TE USB FX2 variable name |
|---|---|---|
C++ API | (not available) | (not available) |
.NET API | CyUSBDevice | TE_USB_FX2_USBDevice |
Table: single device of the device list above.
Most functions, parameters and variables have maintained name and meaning across APIs. A notable exceptions is recalled in the following table.
TE_USB_FX2_CyAPI (C++) APIs | TE_USB_FX2_CyUSB (.NET) API |
|---|---|
TE_USB_FX2_SetData_InstanceDriverBuffer() | (not available) |
TE_USB_FX2_GetData_InstanceDriverBuffer() | (not available) |

- ease binding from Python or another programming language, but also
- make impossible to directly access CyAPI.lib classes and functions to extend Trenz Electronic TE_USB_FX2_CyAPI.dll libraries or CyUSB.lib classes and methods to extend Trenz Electronic TE_USB_FX2_CyUSB.dll library.
