First working version, with cleaner code

Aurnytoraink added 27 commits 2026-07-21 15:42:07 +00:00

Added basic AXI to I2S Tx 048bb710e7

Implementation of I2S bit clock (BCLK) generation 902908d840

Fix I2S clock edge triggering ... cac9da6105

I2S uses falling edge triggering

Seperate controller and worker mode into two indepedant file c15b47b661

Pass FIFO_DEPTH generic to its parent and change the sending packet frequency 56efcf4b11

Implemented the AXI_I2S_TX_WORKER logic into the CONTROLLER version 5ea2ead839

Implement basic triangular wave over I2S 00489f12e5

Fix I2S implementation of AXI_I2S_TDM_CONTROLLER 173c05abd3

Implemented PDM to PCM pipeline for one MEMS 7e09621fe1

Added PDM to I2S project in both master/slave configuration c886e8079b

Rework I2S/TDM logic ... 3f3dac64c2

The sample frequency pulse is now generated using a counter, instead of previous tricky method.
The I2S logic and TDM logic are now shared. Previously, each add a different logic thought the behaviour is similar.

[WIP] Add Programmable Gain Amplifier aa8d2e8387

Update PDM2PCM 61568eca3c

Add AXIS_Recpacket.vhd 2462dcd307

Added CIC Compensate filter (FIR) 20e7072604

Fix IP parameters 8453267db6

Update lib_common ba0c3c392e

Add constraint file ... c71c2f7863

IO mapping and timing constraints

Update project generation for on board recording ... a822a8c308

Now, it generates the project for on-board recording on SD card

Code cleanup and renaming bc2f419f31

New implementation of PDM AXI ... 8c2174627e

This new version send microphone's data in the correct order

New Programmable Gain Amplifier module ... d4c76b3a4d

Though, it still needs AXI-Lite support for configuration
Right now, the gain control is an input port

Update testbenches and regression PDM2PCM ... b2a04d715e

Programmable Gain Amplifier feature have been temporarily removed since it causes timing issue

Update project 75d9cfa270

Added software 0db5732382

Remove all I2S reference ... 1cfa165d8f

I2S project will stay in a different branch

Update project gen and README 3b6e648847
