That looks like really old code from before we added 700 support to the
SM1000

Hi Jan,
Can you confirm which version of Codec2 that you're using? I was trying to
find where that code is and it doesn't appear to be in the latest (

Hi,
I've progressed and the Codec 2 on STM32F4 already works somehow. Now I
wanted to use mode 700 b/sec, but found this *#ifndef*: I can see CORTEX_M4
can not be defined - I am not able to run MODE_700 on STM32? Or what should
I do? thank you. Jan.

Hi Jan
Just adding to the other two very good replies
My experience with codec2 with STM32F4/F7 At O0, the performance may be
down to 50% of -O2, and also, with O0, its likely the compiler is not
exploiting any hardware speedups as with GCC there are some (invisible)
ties between -O level, a
Hi Jan,
We run Codec 2 half duplex (along with a bunch of other modem and FEC
code) on a 180 MHz stm32 and it works just fine in real time. So your
expectations are quite realistic.
The build system we use for the stm32 is in
codec2/stm32/CMakeLists.txt, including C compiler flags (looks like we
Hi Jan,
In the Codec2 library, there are some flags that are turned on in order to
get it to function on the SM1000 (which also uses a STM32F4 series MCU).
You can find out more at
https://github.com/drowe67/codec2/blob/main/stm32/CMakeLists.txt but the
important ones are as follows:
