JeeNodeJR 0.1 credits . based on jcw's <[email protected]> JeeNode work and protocol . uart implementation based on work from njc and hodgepig http://www.msp430launchpad.com/2010/08/half-duplex-software-uart-on-launchpad.html http://blog.hodgepig.org/2010/09/09/573 . rfm12b bitbang spi based on simpleavr's spectrum analyzer http://www.simpleavr.com/msp430-projects/rfm12b-spectrum-analyzer . JeeLabsAndy provides msp430g2553 h/w/ spi code objective . implements JeeNode protocal on msp430 low-end devices . provide basic subset of JeeNode library apis . be able to talk to original JeeNodes (AVR) known differences w/ JeeNode (AVR) . default rf module bitrate is 4.8kbps instead of 49.2kbps . does not support "easy" transmission functions yet . does not support eeprom config r/w yet (2011-09-22) . reduce 32 bytes by adopting to 16bit h/w spi, thanks snowzach . also confirms 2231/2211/2452 h/w spi works on 1,4,8,12 Mhz clock . use cleaner macro to set dco clock from calibrated values (2011-09-12) . provides the following rfm12b functions via rfm.h . rf12_initialize() . rf12_canSend() . rf12_sendStart() . rf12_recvDone() . plus some other internal functions . provides the following uart functions via uart.h . uart_init() . uart_getc() . uart_putc() . plus some other, see source code . communicates w/ rfm12b via spi . choice of h/w spi or bitbang spi . tested on msp430g2211/g2231/f2012/g2452 . should work on most low-end msp430 devices
