DRV8311: SPI frequency Part Number:DRV8311 Hi: In our product is using DRV8311P for BLDC driving, but the SOC can not communicate with DRV8311P. the SOC SPI clock is 25 MHz, Does the frequency is too high tocommunicate with DRV8311P? BR! Bruce Please refer to 69 page of datasheet,...
我们以Firefly 的SPI demo 分析下dts中对spi的描述: /* Firefly SPI demo */ &spi1 { spi_demo: spi-demo@00{ status = "okay"; compatible = "firefly,rk3399-spi"; reg = <0x00>; spi-max-frequency = <48000000>; /* rk3399 driver support SPI_CPOL | SPI_CPHA | SPI_CS_HIGH */ //sp...
