Arduino for STM32

Hello again.
You have worked so hard for me, I am grateful to you for that. however, I was unable to communicate by 23LC512 by the library you edited and sent. It gave the same result. After that, I tried the library and code I added to the first post on the arduino due board which is 3.3v. It also worked. why is this SRAM not working on stm32 card? I will go nuts.

I'm sorry my friend. I made you busy.
There are 2 pieces 23lc512. I have always tried the other 23LC512 with arduino cards. I didn't realize the real problem.
the problem originated from the board.
so it works with STM32.
many thanks again.

I would still suggest you to use address width corresponding to the BUS_KBits, otherwise yo can get unpredictable results.
Even if it seems to work, data may be written to and read from wrong addresses.
