KIT DELIVERABLES : LPC1788 Mio Board. Graphical LCD (TM12864H6CCOWA) USB Cable. (AB) Adaptor 7.5v or 9V/1 amp DC CD that contains, KEIL evaluation version installer, Flash Magic Installer, schematics, user manual and related documents, hex files for experiments, Keil project and workspace for implementing various peripherals and few example project codes. BOARD USE REQUIREMENTS: To test and evaluate the board, we recommend the following configurations PC with 2.0 GHz or higher CPU, 512 MB or above RAM, USB Port, Serial Port and Ethernet Port. (Will need a Parallel Port if a Parallel JTAG is being used) Operating System (We recommend Windows XP, since most of our testing is done on same platform, although other OS can also be used) Integrated Development Environment (We recommend Keil 4.23. Other compatible IDE can be used) Debugging/Programming Tool (We recommend HJTAG, Colink-Ex, Other compatible tools can be used) To test all the features of the board, you would also require a USB Cable (A to B), USB Pen drive, Ethernet cable (straight), a Micro SD Card, If you also need to test the TFT, you will need a Mio Compatible TFT Display Boards provided by CoiNel.

HARDWARE RESOURCES: BOARD Connections The above figure shows the connectivity options available on LPC1788 Mio Board.
I /O CONNECTOR DESCRIPTION: The details of the IO connections are as follows DC Power Input : The Power supply to be used has to be 7.5V to 9V DC, 1Amp. The DC jack connectivity details are shown in the figure. A slide switch is provided for power ON/OFF control. The slide switch is useful only when an external DC adapter is used. Note: Mio cannot be powered via USB When using the adapter, sliding the switch towards the arrow shown in figure will turn the board ON.
JTAG 20 Pin Box Header: The box header will be used to connect the JTAG for Debug/Programming. A 20 Pin IO Cable can be connected here which connects from a Parallel/USB JTAG. For more details on JTAG, check Micro SD Card Connector: The correct way of inserting the SD card is given below. The interface used for SDCard interface is MCI protocol. Pressing the card in the direction shown will lock the card once it will fully and properly inserted. Note: To remove the card, press the card gently in the same direction shown above and then letting it loose. The card will easily pop out and can be removed.
Ethernet: The correct way to plug the connector is given in the figure. Press the connector in the direction shown and the connector will lock up properly when it is fully connected. An Ethernet straight through cable is used for testing. The recommended connection of the cable is also given.
USB CONNECTIONS : The USB provided can either be used as a HOST or an End Device. The USB A Connector is used for the HOST interface, while USB B type for the end device. The jumper setting at J15 needs to be changed depending on whether the USB is used as a HOST or End Device. The details of connections are given below.
Analog Input : Reset and ISP Switch : These switches provided can be used for resetting the CPU and ISP (In system programming) mode. The details of programming the board in ISP mode is given in detail in programming section.
Serial Ports: Onboard 2 Serial ports are provided i.e. UART0 & UART2. The signals are RS232 logic compatible, so it can be directly connected to Computer Serial Port. The UART0 can be used for ISP mode programming. The ISP mode programming detail is provided in programming section. Its printed in the back layer of the board which UART it is.
Graphical LCD Connector: 128x64 Pixels Graphical display can be directly connected to this Port.
TFT 40 pin BOX Header: This connector can be used to connect different TFT (3.2inch, 3.5inch, 4.3inch and 7inch provided by CoiNel. accordingly. These TFT Displays are SPI based and parallel interface and options can be chosen Buzzer/Test LED (D1): A Buzzer/Test LED is connected at P2.21. There is a jumper (J9) to select between Buzzer or LED connectivity.
