It would be nice to have hardware NSS support.
But this does not mean you cannot use SpiDevice
. You can.
With https://docs.rs/embedded-hal-bus/0.1.0/embedded_hal_bus/spi/index.html
This is still software NSS implementation. But it does all staff you need itself. The only you need is to wrap SpiBus
+ OutputPin
in one of the xxDevice
s on initialization.
P.S. We need example in the repo as embedded-hal-bus
documentation is not good enough.
Right now, the spi in the HAL only implements
SpiBus
, which leaves the CS(NSS) management to user software. If theSpiDevice
trait fromembedded_hal
is implemented, then the user don't have to care about the NSS management since it will be taken care by the hardware.I'm relatively new to the embedded world and I was wondering if such implementation will be too complicated to pull off. If not, I'm willing to try implement it myself. Would HardwareCS from the stm32h7 be a good reference to begin with?
Thanks
