* Remove unused bits like the radio event and simplify basic radio interface. It can be more self-contained with rds.h only required by radio and tuner code. * Add post-processing to text a-la Silicon Labs AN243. The chip's error correction can only do so much; additional checks are highly recommended. Simply testing for two identical messages in a row is extremely effective and I've never seen corrupted text since doing that, even with mediocre reception. Groups segments must arrive in order, not randomly; logic change only accepts them in order, starting at 0. Time readout was made a bit better but really we'd need to use verbose mode and ensure that no errors were seen during receiving of time and more checks would be need to have a stable PI. The text is the important bit anyway. * Time out of stale text. * Text is no longer updated until a complete group has been received, as is specified in the standard. Perhaps go back to scrolling text lines in the radio screen? * Add proper character conversion to UTF-8. Only the default G0 table for the moment. The other two could be added in. * Add variants "RDS_CFG_PROCESS" and "RDS_CFG_PUSH" to allow the option for processed RDS data to be pushed to the driver and still do proper post-processing (only text conversion for now for the latter).
