use spi1 and spi2

[hhl-16]

hi guys
can i use spi1 and spi2 for 2 sensors with STM32F407VE
spi1 for dwm1000
sp2 for module micro sd
thanks

Hi,
yes you can. or even use the same SPI instance with a different CS.
SATM32F407VE has 3 SPI peripherals:

Arduino_Core_STM32/variants/STM32F4xx/F407V(E-G)T_F417V(E-G)T/PeripheralPins.c

By default only one instance is defined named SPI, depending of the variant selected, for the generic:

Arduino_Core_STM32/variants/STM32F4xx/F407V(E-G)T_F417V(E-G)T/variant_generic.h

Lines 173 to 181 in b57fab9

	#ifndef PIN_SPI_MOSI
	#define PIN_SPI_MOSI PA7
	#endif
	#ifndef PIN_SPI_MISO
	#define PIN_SPI_MISO PA6
	#endif
	#ifndef PIN_SPI_SCK
	#define PIN_SPI_SCK PA5
	#endif

Which means it uses SPI1.

For other instance you have to define it:
