Arduino-derived development systems:

Forked Arduino development systems with MSP430 Launchpad, Fraunchpad, and Stellaris launchpad support added.

Forked Arduino with PIC32 support added.

Forked Arduino with support for Leaflabs STM32F1-based Maple and Maple-mini boards added. Patches exists for other STM32-F1 board, as well as STM32-F4 support.

My take on this (Udi):

  • MSP430 is dead, as the only reason to buy it in the first place was the $4.30 original price on the Launchpad. Now that the price has rose to $10 and you can get Arduinos for less, why bother? Unless you absolutely need a DIP chip, go buy something else.
  • ST's own STM32 discovery board series gives great value for their price, and are clearly sold at a loss to grab developers mindshare, however, they have no full support by an Arduino fork. We have the Maple software but it is being developed by leaflabs who are probably interested in supporting their boards only. The major hurdle in using ST's boards with Maple is that they probably have a different bootloader protocol (ST/LINK) than the leaflabs boards.
  • The PIC32 boards were interesting when they came out, but now that we have Arduino based and Arduino compatible ARM boards that costs less, why bother?
  • the Stellaris launchpad series is interesting because they give a complete ARM based solution at $13 that can be programmed with an Arduino-like environment


  • Add links for CooCox GUI
  • Add new CooCox boards
  • Add Olimex boards
  • Add pinguino boards and IDE
