LEDs and SPI0
Test setup:
Connect jumpers to all pins of J9 to enable the LED's.
A few seconds after the Blueboard is turned ON or reset; the LEDs will turn ON in ascending
pattern and will turn OFF in descending order and this pattern will repeat three times. Please note
that all the LEDs should glow; this confirms the working of LEDs. Now, since the LEDs are connected
through a serial to parallel converter this test also confirms the working of SPI0 of the LPC.
UART0 & UART1
Test setup:
Connect jumpers to all pins of J6. Open the hyper terminal as shown in the image below.
To test the UART you can use either a full modem or half modem cable.
Click on hyper terminal a “Connection Description” windo
w opens. Enter a name under the
name tab e.g. BlueBoard and click OK.
A “Connect To” window opens where you have to select the COM port. In this example it is
COM1.Click OK.
