Mini-DK board overview (Micro SD connector is at the bottom side)
One serial interface , uses CP2102 (USB to RS232 interface, support ISP download )
RJ45-10/100M Ethernet network interface (Ethernet PHY: DM9161)
2.8 inch TFT color LCD interface (SPI interface or 16Bit parallel interface)
Touch panel controller XPT2046 (ADS7843 compatible)
USB 2.0 interface, USB host and USB Device interface.
TF SD / MMC card (SPI) interface.
Two user buttons, One Reset button and ISP button , One INT0 button, two user-programmable LED lights
Serial ISP download, Standard 20-pin JTAG download simulation debugging interface.
Selection between external 5V power supply or USB 5V supply.
Board size: 95mm * 78mm
All IO available on extension connectors

Erik Olieman (http://mbed.org/users/Sissors/) joined the code development for the Mini-DK board.
Thanks to his input, we were able to obtain a tremendous speed gain, remove warnings, ...
An overview of all modifications is stored in modifs.h
The old page (http://mbed.org/users/frankvnk/code/LPC1768_Mini-DK/) contains the demo code.
IMPORTANT : Due to a change in the mbed libraries (Stream()), we cannot use the printf instruction - we need to use <SPI_TFT>.printf (example - see main.cpp in http://mbed.org/users/frankvnk/code/LPC1768_Mini-DK/)
WARNING: filetoflash (SD to CPU flash)
The SPI_TFT library contains an option to copy an image from the SD card to the CPU flash memory. This allows you to use an image as background without speed loss when writing other text and graphics.
By default, this option is enabled.
It can be disabled by uncommenting the #define mentioned below in Mini_DK.h:
#define NO_FLASH_BUFFER
Since the flash memory has limited write endurance, DO NOT use this feature when you intend to read multiple images from the SD card (eg: when used as a photo frame).
14/01/13
A newer version of the Mini-DK has been released by the manufacturer: Mini-DK2. They replaced the DM9161 PHY with a LAN8720A PHY and better buttons are fitted on the board. All other hardware remains the same. Code for this PHY is available from the NXP MCU SW application team. This allows us to use the mbed 'EthernetInterface' library with little modifications. Further info - see http://mbed.org/forum/mbed/topic/3684/?page=1#comment-18473.
Notes:
The code in 'lpc_phy_lan8720.c' uses 'msDelay' - needs to be replaced with 'osDelay'.
A custom MAC address can be defined using following code:
extern "C" void mbed_mac_address(char * mac) {
// define your own MAC Address
mac[0] = 0x00;
mac[1] = 0x01;
mac[2] = 0x02;
mac[3] = 0x03;
mac[4] = 0x04;
mac[5] = 0x05;
};
