Copy ACIA driver to blkfs We can get rid of acia.z80, but not of acia.fs yet, we still need it.

acia: make wholly cross compilable
vor 4 Jahren
rc2014: add a declaration part to ACIA drivers Driver configuration don't need their own words at runtime, we only need to compile them as literals when compiling words. Now that we have this "declaration blocks" pattern emerging, it seems like a good idea to take advantage of this in drivers, both for simplifying the xcomp unit and to make final binary slimmer.

  1. ACIA driver

  2. 

  3. Manage I/O from an asynchronous communication interface adapter

  4. (ACIA). provides "(emit)" to put c char on the ACIA as well as

  5. an input buffer from which a provided "(key)" reads. This driver

  6. installs an interrupt handler at RST38 to handle RX.      

  7. 

  8. To use, begin by loading declarations (B582) before xcomp is    

  9. loaded. These declarations provide default values for ports and 

  10. memory offsets that you can override. See B582.

  11. 

  12. Then, in the driver part, load range 583-588.
