        let mut buffer = [write_reg[0], write_reg[1], write_reg[2], write_reg[3], 0xFF, 0x10, 0xAA];
        // Set up write latch
        e25x.write_enable();
        let result = e25x.transfer(&mut buffer);

        let mut read_buffer = [read_reg[0], read_reg[1], read_reg[2], read_reg[3], 0, 0, 0];
        e25x.transfer(&mut buffer)?;
        assert_eq!(read_buffer[4], 0xFF);
        assert_eq!(read_buffer[5], 0x10);
        assert_eq!(read_buffer[6], 0xAA);

使用嵌入式HAL实现来获取SPI和一个GPIO OutputPin用于保持线、写保护线和片选。
