Kit Operation
place the UART component in the PSoC 4 BLE or PRoC BLE and assign the UART pins as shown in
Table 3-2.
Table 3-3 lists the specifications supported by the USB-UART bridge.
3.7 USB-I
2
C Bridge
The PSoC 5LP also functions as a USB-I
2
C bridge. In this role, PSoC 5LP communicates with
PSoC 4 BLE/PRoC BLE using an I
2
C interface, and sends that data over the USB to the USB-I
2
C
software utility running on the PC, called the Bridge Control Panel (BCP). This feature is available
for both the BLE Pioneer Kit and the BLE dongle.
The BCP is available as part of the PSoC Programmer installation. This software can be used to
send and receive USB-I
2
C data from the PSoC 5LP. When the USB mini-B cable is connected to
header J13 on the BLE Pioneer Kit or when the dongle is connected to the PC, the KitProg USB-I
2
C
is available under Connected I2C/SPI/RX8 Ports in the BCP, as shown in Figure 3-23.
To open BCP in your system, go to Start > All Programs > Cypress > Bridge Control Panel.
