Thank you ag123.
at last, it got compiled without any errors

followed your instructions but still :oops:

thank you all for your replies and sorry for using the word simultaneously what I wanted to ask is how to use both spi1 and spi2.
I want to use mcp2515 at spi2. I need to modify that library.
what I want to know is what file needs to be modified and how it needs to be modified. I never modified a ...

I want to simultaneously use the st7920 LCD at spi1 and mcp2515 at spi2 on stm32f103c8t6. I am using Arduino ide. some explanation and example code is needed.

can anyone share an example code to use spi1 and spi2 simultaneously in stm32f103c8t6 in Arduino IDE?
