I'm going to give up trying to get a pbp3 version up and running after ,3 days solid I have 2 C versions working and flagging interest for the pbp3 version , with no inbuilt string searching routines my clunky attempts at a strtok(),strcmp() functions on circular buffers (three of them) over 256 bytes in size fed by and feeding interrupt routines is failing miserably ,its hard to compete with well honed C libraries . the task is daunting , at least for me . but I really don't think it would turn out to be much different size wise anyway .the inherent blocking nature of basic and the largish overheads in interrupting it don't help either. maybe you (ioannis or anybody) might like to propose a less daunting comparison to try (I think a simple blinky is not a realistic test its needs a bit more than that something that could use floats if they were available or workarounds if not).
