dceae9e958 implemented adjusting window size. Now it should fit on 1024x768 screens, such as installed on new radar contrapion. (via codex)

86a97aaba2 git tree cleanup .venv directory
5abac34b58 implemented deploy executable. It installs venv, activates it, install dependencies: FreeSimpleGUI, PySerial

c695ee2d0c changed path in venv activate from absolute to generated relative

aeb3d90aec completely working!
8b0c99ab96 fixed port issues on Linux systems. Now ttySx are ignored
f921bec1c3 initiated venv, installed FreeSimpleGUI and PySerial
434f9c0df3 init. Not working due to the malunction of PySimpleGUI lib

5ef974cb78 disabled sending to PF: FFT_Re, FFT_Im
235fa386d2 FFT work mostly correctly with sin signals
b6636a0e83 implemented FFT amplitude dump. Somehow FFT is working, but now it is buggy. FFT results are connected with input signal, but this connection is not straightforward.
0dee57de4d FFT is somehow working. FFT results are dumped to the PC as: 0xF1 -- Re, 0xF2 -- Im. But results are still weird: for both sin and DC signals from ADC it returns periodic waves in FFT results.
417285990e FFT is correctly calculated for dummy (DC = 1.0) data!

5e36a64acb now printf is disabled if twiddles arrays are external. Now while used for emdedded there is no prfintf garbage in compiled code.

86f488e456 replaced twiddles arrays definition by lazy definition (via macros and #ifndef)
ChTheo pushed to master at ChTheo/FFT_and_FP_math 2025-10-09 14:35:40 +03:00
1256c9b807 added fft_twiddle_gen func that calculates twiddles inside provided arrays

f9b5fdf89b included FFT_and_FP_math as submodule. It contains FP-FFT library in FFT_and_FP_math/C

aa5945e8b2 added phase calculation (dummy, always return 0) in imagery2abs. Added FFT_Re, FFT_Im dumping to the output file. Possible issue: phase of simple sin is -1.
73857920b4 scaled FFT result down by DATA_L (normalisation)
580ba1f9f6 replaced huge 2d twiddle arrays by smaller 1d arrays. Now it uses very low memory
f54daffb72 added precalculated twiddles table, fixed accuracy issues (switched from int32 to int64). Now FFT working correctly
1a9f820724 created C folder with FP_math.c, Makefile and plotter. FP_math have a FFT realisation with fixed-point math, and its tester
