Hi,
Not sure if anyone has asked before.
Is there BSP for stm32L451 or other L4 family nucleo? also with RS232 turning driver?
I only have the L451 nucleo board with me,
I have already implemented the DFSDM drivers for PDM Microphone and able to playback to the internal dac with internal op-amp driving a balance armature speaker.
Now I am trying to implement the AWE Core to see what DSP I can do.
Many Thanks

Hi Sam,
There is a reference BSP for the STM32L496 Discovery board on our downloads page: https://dspconcepts.com/downloads
For a sample of a target that uses RS232, check out any of the SHARC BSPs on the downloads page.

Hi Axel,
Thanks for your quick response.
I am using L452RE nucleo boards with 160Kbytes RAM, I am having RAM overflowed at the moment. The example for STM32L496 Discovery has 320Kbytes RAM. I have tried optimised for size but no luck. It seems like there are many static libraries, are all of them needed? Or is there any other ways to reduce the size?
thank you for your help!

To save space on your target, you can trim down the list of modules in the ModuleList.h file that defines the macro LISOFCLASSOBJECTS. For example, removing all of the Fract32 modules will save you a lot of space if you only intend to use Float modules.
