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 microcontrollers 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: one could use either parallel port programmer or NGX ARM USB JTAG
- ISP programming: Programming through the on-chip bootloader using UART interface and Flash Magic
- USB secondary bootloader
