2、Detailed description

 

 

 

 

 

 2.1 Power supply (for source)

Land Rover open board uses an external 5V source into the USB interface to provide the 5V source into.

● 5V DC source adapter received a CN9, that the source jump J3 into the 1-2. External 5V source.

● USB connection to the emulator USB port CN4 source jump J3 into the 2-3, USB 5V source for. Through access from PC head for the (maximum flow 500mA limit).
 









Note: within the core of CN9 outlet cathode outside the core is very. The entry should not exceed 5V ± 5%.

 2.2 Clock source (source)


Land Rover LPC17XX board from three sources: the Department, RTC, Ethernet.

Y1 12MHZ crystal, do the Department's main source, the internal RC shock absorbers Y1 can not answer.

Y2, 32.768kHZ crystal, do the source of the RTC

  U4, 50MHZ crystal, do the Ethernet PHY chip DP83848.

Note: JP1 jump short circuit (short) power  the RTC disconnected when JP1 open (open)

  power for the RTC.

 

 

 
2.3 Reset Mode (reset)

The reset signal in open Land Rover LPC17XX board is a low-lying reset.

Reset include the following:


Reset Press Reset (SW1)

  JTAG emulator controls  of the reset signal

 

2.4 Analog Input

 

 

2.4 Analog Input (Input)

 

The A2D input is via  P1.31 (AD0.5).  JP12 needed to be shorted to connect.

 

 

2.5 Digital Analog Conversion Output （DAC ）

 

The pin P0.26 is connected to the audio amp Speaker  via JP2

 

2.6 USB-HOST

 。2.6 USB-HOST (USB host)

Land Rover LPC17XX open board has a USB A-type USB HOST full-speed interface (CN11).

One can use a USB port then USB, such as: U, USB mouse, USB, etc..

 

USB-A type connector external 5V source (this source by the process control).

To use the USB function need to be JP9 the JP11 two jump into the 3-4 position,

the USB data D +, D-allocation of USB Host interface.

DataFlash's CS, P0.17 pick the DataFlash of the MISO.

2.11 CAN

Land Rover LPC17XX open board supports two-way CAN2.0A / B communication interface. Use SN65HVD230

(U12, U13) for the CAN device. CAN interface leads 5.08mm away from the terminals.

2.12 RS-232 AND RS-485

The way RS-485 communication interface the Rover LPC17XX open board CN10 received UART3 and two-way RS-232

Communication interface COM1, COM2 received LPC1768 the UART0 and UART2. Two control signals ISP and RESET, the same received COM1 RS-232 interface is used to write from your ISP (serial program). To use a serial write programs need to be JP6, JP7 jump are plugged.

2.13 SD card

Land Rover LPC17XX open panel SD card interface received a SSP0 LPC1768's. Signal of the SD card

Received a quasi-IO port P3.25, SD card source control signal received quasi-IO port P3.26.
 

2.14 Ethernet

Land Rover LPC17XX open board 10M/100M Ethernet communication interface, the Ethernet PHY chip

DP83848 (U5) and a wave of RJ45 Connector (CN5). Through RMII interface and

LPC1768 chip connected RMII interfaces.

2.15 Debug Funtion （ 功能）

Land Rover LPC17XX Banban a USB emulator to support the simulation, the next function. Support KEIL,

IAR and other mainstream open environment. The use of the method is fully compatible with JLINK (JLINK) open board is disconnected after the imitation

Really can be used for general-purpose simulation open tool. JP4 control the foot of the emulator, when JP4 open

Board emulator connected to LPC1768 JTAG interface, and then when JP4 short external emulator JTAG port external imitation,


Cut function must be broken and then only came into effect on.
