Arduino for STM32

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

followed your instructions but still :oops: no matching function for call to 'SPIClass::SPIClass(<anonymous enum>, <anonymous enum>, <anonymous enum>)' SPIClass SPI_2(PB15, PB14, PB13); Arduino: 1.8.19 (Windows Store 1.8.57.0) (Windows 10), Board: "Generic STM32F103C series, STM32F103C8 (20k RA...

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 li...

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?
