I’m trying to use the default Drivers/DSP_Lib in my project with the board genericSTM32F103C8.
I’m having issues with the use of arm_rfft_init_q15() function.
arm_rfft_instance_q15 s; arm_rfft_init_q15(&s, AQUISICAO_AMOSTRAS, 0, 1);
When I add the second line above, i’m getting:
.platformio/packages/toolchain-gccarmnoneeabi/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/bin/ld.exe: region `FLASH' overflowed by 28772 bytes collect2.exe: error: ld returned 1 exit status
I think that it’s because the compiler tries to load large tables from this library. I tried to comment this tables, but without effect.
It looks like platformio compiles this library from another dir, so, what dir?
What should do i?
