Hardware
5.1.10 Serial Interconnection Between PSoC 5LP and BLE Module
The PSoC 5LP onboard programmer is also a USB-Serial interface, It supports USB-UART and
USB-I
2
C bridges (see Figure 5-18). The pull-ups resistors on I
2
C bus are enabled when the protocol
is selected from user interface (like bridge control panel). The USB-Serial pins of the PSoC 5LP are
also available on the Arduino header; therefore, the PSoC 5LP can be used to control Arduino
shields with the SPI/I
2
C/UART interface. Refer Using PSoC 5LP as USB-UART Bridge on page 115
and Using PSoC 5LP as USB-I2C Bridge on page 126 for more information on how to use these
serial interconnections
