Hi, just wanted to point to a nice and especially cheap arduino replacement to use for extending NanoNote e.g. via UBB: The TI Launchpad development board
www.ti.com/launchpad This board costs only $4.35 [1] and comes pre-installed with a MSP430G2553 with 16k Flash and 0.5k RAM. A second smaller MSP IC is also included that can be plugged in in place of the 2553. The board has a USB interface handled by an extra MCU for flashing and serial terminal. TI must be pretty desperate, as I cannot see how they don't sell this at a loss. Maybe not be as open-source friendly as the Arduino, but it's not OSS unfriendly per cest (I won't touch the proprietary IDE bloatware called IAR that TI markets for it). On Linux, mspdebug [3] can flash the Launchpad board without problems (as long as I don't use a usb hub). I also had luck assembling hexfiles via a cross-assembler [2], or using a Forth system [4] on it. There's a GCC toolchain, too [5] (IIRC it's included in ubuntu 12.04), but I didn't test that yet. All I/Os are 3.6V, I guess that's close enough to not break the NanoNote when driving the UBB's 3V I/Os as inputs? cheers, David [1] http://search.digikey.com/us/en/cat/programmers-development-systems/general-embedded-dev-boards-and-kits-mcu-dsp-fpga-cpld/2621773?k=ti%20launchpad [2] http://john.ccac.rwth-aachen.de:8000/as/ [3] mspdebug.sf.net [4] 4e4th.eu [5] mspgcc.sf.net -- GnuPG public key: http://dvdkhlng.users.sourceforge.net/dk.gpg Fingerprint: B17A DC95 D293 657B 4205 D016 7DEF 5323 C174 7D40
