If you wish to change the baud rate used through the USB-UART bridge, then you can configure the board controller to use a different speed from it's admin console. The admin console can be reached from Simplicity Studio. Use this guide to change the baud rate in the board controller. ...
这些器件通过高速 AXI 总线连接在一起,能共享和使用大量硬件实施的功能,例如 GPIO、UART、I2C 等。 开发人员通过对可编辑进行复用,可以分配外设功能的配置由哪个内核使用。 UDOO Neo 完整版具有 1 GB 闪存,丰富的 GPIO、串行接口、完整的 Wi-Fi 802.11 b/g/n 和 BLE 连接。 此板配备有嵌入式 9 轴运动传感器...
