Hi Sam,
If you build the codec2/stm32 code, you will create libcodec2.a
There are also many unit test programs, some of them might be close to a
minimal codec 2 demo, and can run on a Discovery card.

Dear Bruce,
Yes, we have considered using FPU of our MCU. I had got a successful build
for codec2 as a pre-assembled library ; however it seems I was working on a
wrong code.

You know floating point is required, right?

Dear David,
The reason I was using https://github.com/piratfm/codec2_m4f instead of
https://github.com/drowe67/codec2 was to have a clean and minimal code for
the core of Codec2 on Cortex M4. Actually, first I tried to port from
https://github.com/drowe67/codec2 but it turned out there are some ma
Use https://github.com/drowe67/codec2
On the SM1000 we also place constant tables in flash, so they won't be
loaded into RAM.
The SM1000 actually runs the full FreeDV stack - so there is a modem and
FEC in there too, plus speech I/O drivers with large buffers. If you
just want the speech codec,

Dear Don, Dear Ammar,
That's a great news. It means 288KB ram and 100MHz clock would be enough.
The code I was running on the MCU was base on the rate of 2500. This can be
the reason and it seems I need to change it to slower bit rates; however,
As far I looked through the source code, (
https://g
The CPU on the SM1000 is an STM32F405 with 192k of SRAM.
It will not hold a full Codec2 build with all of the modes enabled!
If you look at stm32/CMakeLists.txt in tge source you will see this:
add_definitions(-DFREEDV_MODE_EN_DEFAULT=0 -DFREEDV_MODE_1600_EN=1
-DFREEDV_MODE_700D_EN=1 -DCODEC2_MO
That should be available in its datasheet. But when I ran only the encoding
part on a DSP kit, it took around 200KB.

Dear Ammar,
Codec2 in the project SM1000 is implemented on STM32F MCU family, which
have between 96KB and 386KB of Ram and CPU clock of 96MHz to 180MHz.
The question can be, does SM1000 have external RAM? If no, how much Ram
does the MCU have inside?

Hi there Sam. I think your properties are not enough . I tried this on DSP
DSK6713 Kit also. I came to conclusion that it will require something with
minimum 1GB RAM with a good speed. And If you want real time action, using
interrupts is an option

Hi All Codec2 developers!
I am trying to port Codec2 on Cypress PSOC 6 with 288KB of RAM and 100MHz
clock on Arm cortex M4; however, it seems codec2 is running out of memory
on this MCU. I was wondering what the minimum requirement of RAM and CPU
are for codec2? On the project SM1000 it was mention
