|

|

Some of the pins, such as GPIO0 or GPIO2, have multiple functions and some of them are shared among onboard and external peripheral devices. Certain combinations of peripherals cannot work together. For example, it is not possible to do JTAG debugging of an application that is using SD card, because several pins are shared by JTAG and the SD card slot.
|
||||
|
||||
In other cases, peripherals can coexist under certain conditions. This is applicable to, for example, LCD screen and SD card that share only a single pin GPIO21. This pin is used to provide D/C (Data / Control) signal for the LCD as well as the CD (Card Detect) signal read from the SD card slot. If the card detect functionality is not essential, then it may be disabled by removing R167, so both LCD and SD may operate together.

部分管脚具备多个功能，可供板上组件或外部硬件设备同时使用，比如 GPIO0 和 GPIO2。由于管脚限制，一些外围设备不可同时使用，比如，由于 JTAG 和 SD 卡槽需共用部分管脚，因此一些使用 SD 卡功能的应用无法同时进行 JTAG 调试。
|

其他情况下，不同外设可同时使用。比如，LCD 屏幕和 SD 卡仅共用一个 GPIO21 管脚，可以同时使用。该管脚可为 LCD 屏幕提供 D/C（数据/控制）信号，并用于读取来自 SD 卡槽的 CD 信号（卡检测信号）。如无需使用卡检测功能，开发人员还可以通过移除 R167 来禁用该功能。此时，LCD 和 SD 卡槽可同时使用。
