as clock source.
EM-LPC1700 evaluation board has two clock sources:
EM-LPC1700 evaluation board has recording and playing functions, the audio file can be
played through the external speaker, and the jumper JP6 controls the DAC output and
speaker connection.
EM-LPC1700 evaluation board exports two UARTs, UART0 (COM1) and UART1 (COM2).
These two UARTs are both connected to male DB9 connectors. UART2 supports RTS/CTS
handshake signals.
UART0 the signal definition of RS232 DB9 male connector:
EM-LPC1700 evaluation board supports two power supply modes; you can select one of
the two power supply modes below through JP12 configuration.
1) Supply 5V DC through power jack (JP11) on the board.
2) Supply power through USB connecter (CON1) on the board, the current should be less
than 500mA
