"Optional pointer to function for switching between I/O streams." Is it used to select where to read/write console? I'm asking because it could be useful for me to be able to use i2c/spi/usb instead of uart. |
Beta Was this translation helpful? Give feedback.

Yes, but it is not needed for switching if the switch is permanent. Currently this function is only implemented in a few drivers - those that support a network connection. If not available replace the other entry points in your initialization code. FYI I have a few changes coming in the next build that allows more flexible use/handling of streams. |

Yeah, it should be permanent. In any case the console is a io_stream_t, so I can use any I/O I want, as long as I turn it into a io_stream_t . Right? |

Correct, for core use only non-optional functions needs to be implemented. |
