Mixture of data types causing brain failure #129
Description
When I created my Serial toolkit it took some time to get int getchar_timeout_us (uint32_t timeout_us) working.
I failed to spot the return type was int and as I was expecting a byte back, used uint8_t. Only after a bit of debugging (all praise the PicoProbe) did I figure out my mistake.
Additionally, the values for PICO_ERROR_GENERIC and PICO_ERROR_TIMEOUT are not explicitly documented in the SDK pdf - there is the reference to the PICO_ERROR_ family but you don't find that if you search on the whole string. I ferreted them out of the source which was when I joined up the dots.
