What tools to use?
Our products are in general not tied up to one particular tool. All the tools that support lpc1700 cortex-M3 series of micro controllers can be used, to name a few:

• KEIL uvision4 IDE a 32K code limited version could be used
• Rowley Crossworks comes with 30 day evaluation version
• IAR workbench a 32K code limited version could be used
• And off course GCC based open source tool chains
• For those who wish to program (hex files) using parallel port programmer could consider H-JTAG

How to program the board?
There are various options:

• JTAG interface: parallel port programmer or NGX ARM USB JTAG
• ISP programming: Programming through the on chip boot loader using UART interface and Flash Magic
• USB secondary bootloader
