FTPC Bridge (First Touch PC Bridge)
The PC bridge consists of the CY8C24894 Hub. It contains a 16-pin connector to connect to the
MultiFunction Board for application data exchange.The FTPC Bridge is the interface bridge between
the expansion card, your PC, and the various applications.
Since the FTPC Bridge enumerates as a special type of 'composite device' that contains a PSoC
Mini-Prog interface, the standard PSoC Programmer utility can identify and communicate with the
FTPC bridge.
Universal Serial Bus (USB) is used to establish communication between the FTPC Bridge and a host
controller (usually personal computers).The FTPC Bridge acts as the interface bridge between the
expansion cards, your PC, and various applications such as PSoC Designer and the PSoC
Programmer utility. The master CY8C24894 also acts as a PSoC programmer and downloads the
firmware hex file on to the application.
The ISSP programmer programs PSoC ICs with
.hex
files created with the Cypress PSoC Designer
software. The programmer programs a PSoC chip mounted on your PCB, one at a time. It connects
to your PCB with a 5-wire cable and to your PC with a USB cable. Programming operation can be
automated by incorporating the programmer into a PC-based test system. The tester software
communicates with the programmer-control software through a command-line interface.
