Virgil Dupras 013a3b74c8 Add the concept of unit tests 
Will be much much easier to tests new core routines without having to
re-create their context first.

Also, extract parse.asm from core.asm

Virgil Dupras ede228374c fs: allow fsNext to skip more than one block 
When B>1, fsNext failed because HL was changed in the Seek call.

Virgil Dupras 1ea5bedb4f blockdev: fix broken blkSeek/blkTell 
scas didn't warn about this, but it seems that `jr` calls were out of
range. Seek and Tell was broken. Replacing `jr` with `jp` does the
trick.

Virgil Dupras c77d96da22 blockdev: clarify routines specs 2019-05-12 11:45:08 -04:00
Virgil Dupras 34ee91a0d7 zasm: use blkdev IDs as input and output 
This will soon allow use to seek and tell on input, which is necessary
for a second pass which is necessary for forward symbol references.

This require making `blkSel` a bit more flexible. Rather than having one
global selected blkdev, each app can select its own, in its own memory
space.

Virgil Dupras d8bc9c2bdd parts/z80/sdc: implement blockdev's GetC 2019-05-09 10:47:57 -04:00
Virgil Dupras 54d0286486 parts/z80/sdc: add sdcSetBlkSize and sdcReadBlk 2019-05-08 20:08:17 -04:00
Virgil Dupras 12ca2bd53e parts/z80/sdc: add sdcInitialize 
Also, adjust SD card recipe. Straightforward initialization and read!
 2019-05-08 16:03:54 -04:00
Virgil Dupras ef11059382 parts/z80/sdc: new part 
Incomplete, but what it does *does* work. I could handshake CMD0+CMD8 on
a MicroSD HC.
 2019-05-07 14:50:24 -04:00
Virgil Dupras 59b0c83b0e shell: add iowr and iord 2019-05-02 15:18:47 -04:00
Virgil Dupras 57c3dfece8 zasm: assemble multiple lines at once 2019-04-30 15:51:39 -04:00
Virgil Dupras 055e0d7a31 Split parts in two: z80 and avr 
Also, clarify the role of recipes.
 2019-04-25 16:03:45 -04:00
Virgil Dupras a391f85c00 fs: implement GetC, PutC, Seek and Tell on file handle 
Very coarse, but I got them to work.
 2019-04-23 19:42:10 -04:00
Virgil Dupras f00334ec89 fs: add private "blk" routines 
This way, we can interact with the mounted FS even when we change the
selected blkdev.
 2019-04-23 15:50:26 -04:00
Virgil Dupras 3ba0a707e7 blockdev: remove a layer of indirection in block routine storage 
This will facilitate "copying" blk selection in FS.
 2019-04-23 15:03:23 -04:00
Virgil Dupras ad217c018e fs: implement block reuse in fsAlloc 2019-04-23 14:00:54 -04:00
Virgil Dupras 684f083e8e fs: add "fdel" command 2019-04-23 13:29:16 -04:00
Virgil Dupras 5eca14d49a fs: implement fsNext 
This allows more than one file to be allocated. `fls` properly lists
multiple files.
 2019-04-23 12:04:09 -04:00
Virgil Dupras 1a6d285d2d fs: always read whole block meta in memory to avoid seeking 2019-04-23 10:54:56 -04:00
Virgil Dupras c0dbee78de New part: fs 
Very incomplete, but if you play your cards right, you can, with the
shell:

1. Create a new CFS
2. Mount it
3. Allocate a file with an arbitrary name
4. Have it listed with `fls`
 2019-04-23 09:37:22 -04:00
Virgil Dupras 07fde3cab5 blockdev: move the new seek mode logic into the seek command 
It wasn't a good idea to complicate all blockdev impls with complicated
seeks. Let's just stay in absolute mode for now.
 2019-04-23 08:33:32 -04:00
Virgil Dupras f87cd0485a blockdev: make "seek" print out its resulting position 
Also, extract commands into blockdev_cmds to avoid making blockdev
dependent on stdio.
 2019-04-22 22:54:23 -04:00
Virgil Dupras 5071ee9f40 Extract "stdio" part from shell 2019-04-22 22:41:37 -04:00
Virgil Dupras 8b7faa1f02 blockdev: add "type" argument to blkSeek 
Allows seeking forward, backwards, to the beginning, to the end.
 2019-04-22 22:28:35 -04:00
Virgil Dupras d3d229a918 shell: support string arguments 
No consumer yet, but it's coming...
 2019-04-22 21:52:33 -04:00
Virgil Dupras 1bcceb949c blockdev: add Tell and fix blkGetCW 
Calling on blkGetC repeatedly was somehow very unstable and often
failed. I didn't pinpoint exactly why, but keeping the call addr around
and calling that instead seems like a better idea anyway.
 2019-04-22 17:15:59 -04:00
Virgil Dupras 196d22c4ab shell: add "save" command 
The opposite of "load"
 2019-04-22 16:01:31 -04:00
Virgil Dupras b4694225c5 blockdev: change GetC API 
Instead of waiting, GetC always return immediately, with Z indicating if
something was fetched. The "wait" loop is implemented by the called (and
in the new `blkGetCW`).

This simplifies out-of-bounds verifications for storage blockdevs.
 2019-04-22 14:26:16 -04:00
Virgil Dupras fc0cdede55 Move print(n)str from core to shell 
These routines had hardcoded references to ACIA and didn't belong to the
core.
 2019-04-16 19:45:05 -04:00
Virgil Dupras ff99062d5b Move RC2014 recipe in its own folder 
Also, remove `parts/platforms`. It makes no sense. Only recipes make
sense.

Virgil Dupras 056de2b19d doc: add glue code section 2019-04-16 11:26:58 -04:00
Virgil Dupras 7060ee4dc5 Add Status section to README 2019-04-16 10:52:29 -04:00
Virgil Dupras 21eb64f751 blockdev: remove one layer of indirection 
The approach used for shell extra commands also works for blockdev. Much
simpler and tighter this way.
 2019-04-16 10:17:25 -04:00
Virgil Dupras a27da6f41a add mmap part 
This also introduces the "seek" shell command.

Virgil Dupras ce49fc15d0 blockdev: reorganize routine pointers 
Also, add dummy seek reoutine.
 2019-04-15 21:56:15 -04:00
Virgil Dupras a5addc989c shell: rename seek to mptr 
going to use `seek` for block devices
 2019-04-15 20:42:12 -04:00
Virgil Dupras c996da8ac8 shell: add error codes to cmds 2019-04-15 20:38:25 -04:00
Virgil Dupras 12c23f52e0 Add blockdev part 
Also, add the ability for parts to define extra shell commands.
 2019-04-15 16:53:11 -04:00
Virgil Dupras 4600b5299c shell: place cmd metadata next to the routine 
This will facilitate the inclusion of extra commands other parts might
want to define.
