I wanted to get a sense of how many people out there use the printf library provided in TinyOS 2.0. As its written right now, its not the easiest thing to use since an application has to explicitly flush the printf buffer itself and any printf commands called while flushing will all fail.
My question is whether people would prefer to have a bit more user friendly version of printf. I have an alternate implementation where all that needs to be done to use printf is to include tos/lib/printf in your include path in your makefile. No wiring, no nothing. Just call printf() anywhere in your code and see the output spit out over the serial line. Flushing is done automatically, and bytes can also be written to the printf buffer while this flush is occurring. Since flushing is only triggered when the print buffer has a certain number of bytes in it, explicit flushes are of course possible, by wiring in a PrintfFlush interface from the PrintfC component. The reason I'm bringing all of this up is that this version of the printf library is incompatible with the version in previous releases. Would people prefer to have this newer version overwrite the current one (possibly breaking existing code), or be provided as an alternate printf service in some way? Comments are welcome. -- ~Kevin _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
