89:936f37f90cc2 2019-10-03 roryhand WIP - minor changes on this old branch default
88:76a4563ee9c7 2019-10-02 roryhand WIP - branch. Have performed tests where I have the exact same number of classSoundFile objects, but have no issues unlike in the top branch. Makes absolutely no sense whatsoever.
87:f5c9beae06ac 2019-10-02 roryhand WIP - still isn't working LargeFile_Tests
86:404ce47e1e6e 2019-10-02 roryhand WIP - there is a memory problem that doesn't make sense. I have DEFINITELY filled up memory more than this. LargeFile_Tests
85:e0c9ba778ae0 2019-10-02 roryhand WIP - as soon as i add in one more very small classSound object, the whole thing falls over. absolutely no point doing this project, mbed's resources on this chip are CRAP LargeFile_Tests
84:0a259e261532 2019-10-02 roryhand WIP - have switched to this branch as I could not get this to work without "blipping" in the later commits LargeFile_Tests
83:5b61f67f3020 2019-10-02 roryhand makes weird "pfft pfft pfft" noise when I dont use "Sound1.data_sptr" directly, but only indirectly LargeFile_Tests
82:3694ee23a4d7 2019-10-02 roryhand WIP - trying to get errors out of the main loop LargeFile_Tests
81:ec3a68c93bee 2019-10-01 roryhand WIP - trying to get new block logic working LargeFile_Tests
80:9c70dc3fc16b 2019-10-01 roryhand WIP - minor changes. think my issues are all to do with pointers. can i cast to type without using pointers, so as i can advance wherever the heck i want to within a file? LargeFile_Tests
79:00cc7799407f 2019-10-01 roryhand WIP - the issue i am getting here does not make any logical sense. Once I have assigned a variable, it should not make any difference if i change the variable i assigned it to LargeFile_Tests
78:69a0c7a5fbdf 2019-10-01 roryhand seem to have solved this issue by reading everything for wav 2 into Sound2.FileInfo. LargeFile_Tests
77:e93c944ed30f 2019-10-01 roryhand WIP - there is a bug which makes NO SENSE. If i assign data to data_sptr2, then we only hear file 2. But if we dont have this then we only hear file 1. LargeFile_Tests
76:9535aedba4da 2019-10-01 roryhand WIP - ISSUE STILL HERE. does not make any sense. An fread up in the problem code can take 3000-odd micro seconds to occur. however only takes between 7 and 22 us to occur in the regular "notch" section at the end. LargeFile_Tests
75:8a71e269b890 2019-10-01 roryhand WIP - ISSUE - appears to take 3000-odd micro seconds to perform freads in this section. CHECK how long it takes in the section that works! LargeFile_Tests
74:e71a7815f63d 2019-09-30 roryhand WIP can play a single sound but can't do the fading yet (just sounds bitty and horrible for no apparent reason). LargeFile_Tests
73:a5ab93214728 2019-09-30 roryhand WIP - This should do something, but instead get "Mbed OS fault handler. FAult type: hard fault" error LargeFile_Tests
72:599068243a0f 2019-09-30 roryhand WIP - believe most of this logic is here? Now need to implement handshaking flag system? LargeFile_Tests
71:1364f7d7bff3 2019-09-30 roryhand WIP - more changes LargeFile_Tests
70:2b144da2c3b8 2019-09-30 roryhand WIP - still adding logic to the FadeIn stuff in Play_WaveFileLoop LargeFile_Tests
69:df10ee3ad523 2019-09-29 roryhand WIP - have added some of the logic required into the Play_WaveFileLoop Fnc. LargeFile_Tests
68:55e26c5e837b 2019-09-29 roryhand WIP - more minor changes LargeFile_Tests
67:043fe0b81343 2019-09-29 roryhand WIP - Now contains Nothching up ISR and some other things. The main WaveFileLoop code can now be modified! LargeFile_Tests
66:edf370edd21c 2019-09-29 roryhand WIP - NotchUpIsr() and NotchDownIsr() copied from another commit. LargeFile_Tests
65:8b6a4e307941 2019-09-29 roryhand WIP - Added in a new class: classFade LargeFile_Tests
64:6061ffe25985 2019-09-29 roryhand WIP - copied over "FadeDataInitialise" function LargeFile_Tests
63:a8c1971d3d42 2019-09-29 roryhand WIP - Have now added various new elements to classPositionIndicators LargeFile_Tests
62:ac63dfe15ef9 2019-09-27 roryhand Version to Read in all the different notch transition files and output their start and end times.
61:212d2db45c56 2019-09-27 roryhand WIP - adding in the stuff to do switching between files LargeFile_Tests
60:36df2997de3d 2019-09-27 roryhand WIP - MILESTONE - Seem to be able to loop round a "file" within a file. LargeFile_Tests
59:8e7c25a915a0 2019-09-27 roryhand WIP - when playing the largest file in a loop, you can hear a "blip". why?? Was this to do with the way that Audacity puts this all together? LargeFile_Tests
58:a174e7a8f5f2 2019-09-27 roryhand WIP getting a mad error. Warning L6320W: Ignoring --keep command. Cannot find argument 'os_cb_sections'. LargeFile_Tests
57:0c76b15cabaf 2019-09-27 roryhand WIP - part way through changing this to work for one large "Notch Sounds" File LargeFile_Tests
56:3755c53ac4c6 2019-09-27 roryhand WIP - Commented out stuff to read in a bunch of files, the files do indeed include 44 byte long headers. Now to start playing loops from one large file!
55:5a441d3b0d57 2019-09-23 roryhand WIP - trying to read in sizes of data, so as we know whereabouts our file position indicators will need to go to, when all the sound is amalgamated into one huge file
54:606a83fff291 2019-09-23 roryhand WIP - version before seeing data sizes
53:954e8ac1df17 2019-09-15 roryhand wip - just makes a stupid sinusoid noise now WHY
52:3372052bb105 2019-09-14 roryhand wip - have taken out the fopen and close stuff, but still getting horrid "spitting" noise
51:dab013a902bd 2019-09-14 roryhand wip - playing stuff but still not correct. try and solve on Mon. 16/09/2019
50:78ded157e9bb 2019-09-09 roryhand Added in appropriate stuff. Yet it does not work yet. Sounds terrible...
49:ce6b36eb0d88 2019-09-09 roryhand wip - not finished and doesn't even compile at the moment
48:01490448a05a 2019-09-08 roryhand WIP - beginning to add in extra code to make Transitions between notches work. Haven't figured out how to get passing in the names to work, but this will come later. Need to check that opening and closing dynamically wont stop it sounding good!!
47:9334a8f54997 2019-09-08 roryhand FINISHED - a basic Fade In demo. We aren't even using a switch on the input, and we have not yet written block 2. We also need to add in appropriate code to make fclose of different files work (hopefully)
46:de390e45c2af 2019-09-08 roryhand WIP current iteration, still not quite working
45:0e8e1f2ec5d2 2019-09-08 roryhand WIP - only seems to play a file. The FAding is not working (turns out the fade coefficients are NOT being recalculated!)
44:a9e84d333a6a 2019-09-08 roryhand WIP - Adding in appropriate info to use new method of sharing objects, Tristan and Rory idea
43:890d76ffe627 2019-09-07 roryhand WIP - more vectors stuff removed
42:f481dcabdc34 2019-09-07 roryhand WIP - Some vector junk removed, in prep for new method after conv. with Tristan
41:5dca752e6c40 2019-09-07 roryhand Last version to contain any mention of Vectors. Will be doing this another way after conv with Tristan
40:ba34990514fa 2019-06-17 roryhand WIP - Can now print out members of vectors, and delete vector elements. However, deleting an element does not leave an empty element. Need to find a way to replace any given deleted element with a placeholder (low memory) element.
39:69d5a5dd9163 2019-06-17 roryhand WIP - added in vector tests (not working at all, probably a stupid hardware issue as per usual)
38:3b4c05af5f36 2019-06-02 roryhand WIP - makes no sense. I can open up 15 files and close them one by one. But I CANNOT do this if it is done via Sound[aaa].FileInfo.WavFile... It will then hang....
37:a563899ac0df 2019-05-27 roryhand WIP - Added in code to take logs of file names (non-interactive)
36:569ec4335f92 2019-05-27 roryhand WIP - just changing classSoundFile
35:4469b508dda3 2019-05-27 roryhand WIP - Can open wav file within play_wavefiledual and play it (with slight pause).
34:26118c8f2e48 2019-05-27 roryhand WIP - Can open another file whilst playing one such file (the file we are opening is unrelated to the 2 we are trying to play)
33:a75f0a30fbdc 2019-05-26 roryhand WIP - testing to see if we can switch files inside the main play loop.
32:6ee488c97dcc 2019-05-26 roryhand WIP - can transition between files naturally IF FILES ALREADY OPEN.
31:0f8c3adf09c3 2019-05-26 roryhand WIP - Have now discovered that the opening and closing may only take 5us and 13us respectively. Does this mean we can solve our overall problem?
