33:a0dab92ea1b9 2020-01-06 bmazzeo Slight change to improve the function specifications for Erase_Trace and Draw_Trace
32:96ec424e10e6 2020-01-03 bmazzeo Release on January 3, 2020 for ECEn 487 Laboratory 1 exercise.
31:5a0235b66851 2020-01-03 bmazzeo Updated the code so that way a user can download the code, compile it, and use it. It has the basic outline for the first laboratory activity.
30:debea332cdfe 2020-01-03 bmazzeo Code with more extensive commenting. Set to 2 kHz carrier. Working well.
29:7d3fff4ac41b 2020-01-01 bmazzeo It works - perfectly - for carrier frequency of 500 Hz.
28:fe7747b89fb3 2020-01-01 bmazzeo DOA computes phase angle correctly (it appears) - conversion to degrees still needs to happen.
27:0d65cfcc9001 2020-01-01 bmazzeo Just cleaned up - changed the signal processing block size to be the same as the half block size - this cleans up the code considerably - but uses a bit more memory.
26:023edf8cea6c 2020-01-01 bmazzeo Just changed the display of information to put a bit more in first half block and take some from second half block.
25:5412779376a7 2020-01-01 bmazzeo Working example!!! - L channel has lowpass filter. Proper initialization of filters is performed. Output is clean.
24:9ac1187f9012 2020-01-01 bmazzeo Functioning DSP block using arm_fir_f32 and the older dsp library to run it - but there may be some errors because some strange outputs were occurring in the output.
23:d938f87dd1ee 2019-12-31 bmazzeo Successful inclusion of signal_processing.cpp to handle all of the processing for both blocks simply.
22:f36d7a53bb7e 2019-12-31 bmazzeo Floating point conversion and back for both blocks
21:4dbfda694c0d 2019-12-31 bmazzeo Working audio to float conversion and float to audio conversion.
20:2ecdf687a2d1 2019-12-31 bmazzeo Conversion to float successful.;
19:479f611941a8 2019-12-31 bmazzeo Cleaned up version before starting float conversion.
18:255d15af49f2 2019-12-31 bmazzeo Single trace with two channels working excellently. Good place to revert to if there are problems in the future.
17:eb85a2387dd4 2019-12-31 bmazzeo Plotting Left and Right combined in single trace.
16:b7dca59ab076 2019-12-31 bmazzeo Working version with traces working - and now correct data types defined.
15:83e40ccc1b1f 2019-12-30 bmazzeo Some things working with floats and such - but also many things broke - so this is committed before working with previous revision.
14:18f159d48340 2019-12-30 bmazzeo Audio to float, Float to audio function first prototyped here.
13:61131aac4031 2019-12-30 bmazzeo All code nicely organized - displays timing and traces.
12:e44766b61346 2019-12-29 bmazzeo Working with sampling and displaying.
11:4256dbbb0c89 2019-12-29 bmazzeo Cleaned up a few lines
10:a82b64ea1d11 2019-12-29 bmazzeo Complete with timing indicators for different cycles
9:f5b37c71856d 2019-12-29 bmazzeo Better - because signaling is correct - yielding appropriate timing (still need to correct audio block lengths).
8:d1c41eca57f0 2019-12-28 bmazzeo Excellently working code - shows the audio in real-time.
7:e1dfd64eba81 2019-12-28 bmazzeo Graphics (oscilloscope working) engaged and showing microphone data.
6:e689075b04ed 2019-12-28 bmazzeo First working version with graphics and some display of audio numbers.
5:66c230f74325 2019-11-20 Jerome Coutant Update with STM32Cube_FW_F7_V1.15.0
