Development

You can get you development environment ready for Friday right now!

LPCXPresso is the development environment for NXP devices, however it's only available for Windows and Linux (beta). We've created a pre-configured, Linux-based Virtual Image that can be imported into VirtualBox, a free Virtualization utility available for Windows, Linux and OSX. Download VirtualBox Here:

• VirtualBox 3.2.8 for OS X (Intel) hosts

The Virtual Image will be available on both DVD and on the SoOnCon file server (OMEGA) along with Virtualbox downloads at both events.

There is a GitHub repository available for the library code at git://github.com/egerlach/arduinizer.git Pull requests welcome!

Badge Code

Original Development Code for importing into LPCXpresso is here: http://www.generik.ca/Arduinator.zip

Notes

Mounting the badge

Hold the left two buttons as you insert the USB cable. This will put the badge into programming mode.

Loading firmware on Linux

1. Make sure that mtools is installed (standard on most distros)
2. Un-mount the badge (it automounts on many systems)
3. sudo mdel -i /dev/sdb ::/firmware.bin ; sudo mcopy -i /dev/sdb Arduinizer.bin ::/

Errata

• Bottom green LEDs are non-functional.
  • Q8 gate is driven by to PIO0_5, an open-drain output.
  • Fix: Add pull-up resistor to VSYS.
