In a word, is it fully supported (write/compile code, download, debug, etc.)? When I hear that spybiwire is fully supported then my reaction is joy and happiness. But when I hear that the MSP430X instruction set is not supported I wonder to what extent the eZ430-xxxx is supported, if at all. Please clarify. When I mention MSP430-XXXX, I mean the current F2013, and the up-coming device with the CC2500 R.F. transceiver (don't have any more details). Thanks for the clarification. Dave,
