I have a program made and working on Arduino Nano, but due to the processing capacity I had to change to STM, but when doing the conversion I get some errors.
Hello @Lopinhos and welcome to the ST Community :smiling_face_with_smiling_eyes:.
What I understood from your question that you want to do a migration from Arduino Nano to black pill. I suggest you to use the STM32duino for this migration ( STM32 Arduino (STM32duino) Tutorial will be a good start).
Best Regards.

Yes, basic Arduino codes work perfectly on the STM32, but the code I needed to use on the stm32 is giving me several errors, which are in the SPI communication part.
