hi,snip.spi_slave-RB_DUO not working.
i added it to make file. VALID_PLATFORMS += RB_DUO \ RB_DUO_exterror message;
VALID_PLATFORMS += RB_DUO \ RB_DUO_ext
I would be glad if you help. Thank you.
Sorry, most of the MCUs in the SDK haven't been implemented the SPI slave driver, except those platforms listed in spi_slave.mk by default. Those valid platforms have implemented the SPI slave driver within the pre-built libraries under WICED-SDK-3.7.0\WICED\platform\MCU\BCM439x\peripherals
so does that mean that redbear duo doesn't support spi slave operation in wiced sdk?
Nope. Though it is a little difficult, you can implement these functions yourself.
