stm_fft slow blink PC13 on bluepill

[78edu]

Hello. I've tried stm_fft library and it doesn't work. My bluepill board PC13 led starts pulsating slowly and board is not responding. I've installed Arduino_STM32 by an archive to my Documents folder and Arduino SAM boards in Board Manager. All works fine, but not this library. Arduino uses: "C:\Users\1\AppData\Local\Arduino15\packages\arduino\tools\arm-none-eabi-gcc\4.8.3-2014q1/bin/arm-none-eabi-g++" And no *.asm file is compiled. With .s extension it compiles as with -o nul: "...\libraries\stm_fft\cr4_fft_256_stm32.s" -o nul" I have no idea how to properly compile this files and link it. I've tried info from other issues on this topic with no result. STM32duino toolchain is different and i don't know how to use it, it fails in many places. In my case 1024 fft is failed too. (In my case version 1.9.0 with xpack-arm-none-eabi-gcc-9.2.1-1.1, i'll try with 1.6.1 arm-none-eabi-gcc 8.2.1-1.7)

What should i do to use this library?

After installing STM32duino 1.6.1 arduino uses arm-none-eabi-gcc 8.2.1-1.7, but i still have pulsating led issue. .asm files also ignored, but not .s, all remains same (maximum verbose output)

Please use www.stm32duino.com for such issues.

can you explain details? it won't compile with stm32duino with manually added library. should i use cmsis dsp instead of stm_fft? I prefer Arduino STM32 more than stm32duino, it works much faster and i need stm_fft to work.

c:/users/1/appdata/local/arduino15/packages/stm32/tools/arm-none-eabi-gcc/8.2.1-1.7/bin/../lib/gcc/arm-none-eabi/8.2.1/../../../../arm-none-eabi/bin/ld.exe: C:\Users\1\AppData\Local\Temp\arduino_build_326228\sketch\sketch_may17a.ino.cpp.o: in function `loop':

sketch_may17a.ino.cpp:(.text.loop+0x26): undefined reference to `cr4_fft_1024_stm32'

collect2.exe: error: ld returned 1 exit status

In both cases (stm32duino and arduino stm32): stmf1_fft\\cr4_fft_64_stm32.s" -o nul What's the point? Compile .s file with no -o file output?

I suggested to use the forum www.stm32duino.com. There you can post your problem and get response if you provide more information.

Please don't close this issue until 10.07.2020. I'll try to figure how to fix this. I think this should work proper because it's main fork library.

Why 10.07.2020

[stevstrong]

I suggest to change the extension ".s" to ".S" (capital S), then it should compile.
