3.1FTPC Bridge Details
The FTPC Bridge is the interface bridge between the expansion cards, your PC, and the various applications such as PSoC Express™, PSoC Designer™, and the PSoC Programmer utility.
Since the FTPC Bridge enumerates as a special type of ‘combo device’ that contains a PSoC Mini- Prog interface, the standard PSoC Programmer utility can identify and communicate with the FTPC bridge. This ensures that your FirstTouch Kit is automatically compatible with both PSoC Express and PSoC Designer.
