[参考译文] LAUNCHXL-CC1310：GPIO 引脚的配置过程

我使用  uartEcho 示例并进行以下修改：

const PIN_Config BoardGpioInitTable[] = {

};

我可以从应用程序控制 DIO25：

void *mainThread(void *arg0)
{
char input;
const char echoPrompt[] = "Echoing characters:\r\n";
UART_Handle uart;
UART_Params uartParams;

/* Call driver init functions */
GPIO_init();
UART_init();

/* Configure the LED pin */
GPIO_setConfig(Board_GPIO_LED0, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);


GPIO_setConfig(Board_GPIO_TEST_DIO25, GPIO_CFG_OUT_STD | GPIO_CFG_OUT_LOW);

GPIO_write(Board_GPIO_TEST_DIO25, 1);
GPIO_write(Board_GPIO_TEST_DIO25, 0);

你好，Siri

感谢您的答复。

我已经将  CC1310_LAUNCHXL_GPIO_TEST_DIO25添加 到  CC1310_LAUNCHXL.h 文件中、构建时出现以下错误：

错误#41:需要一个标识符

此外、我认为您在上面的第三个代码段中犯了一个错误。 我只能  在   CC1310_LAUNCHXL.c 中找到 BoardGpioInitTable 阵列

你好，Siri

很抱歉、即使此问题已解决、但在给定上述配置的情况下、这些引脚都是特定于 GPIO 的、即它们与任何外设都没有关联。

我提出问题的原因是、我现在有一个带有 CC1310的定制板、其中的 SPI 引脚已重新映射。 从 uartEcho 示例中、我可以看到默认的 SPI 引脚、 除外 CSn 引脚在  BoardGpioInitTable[]中配置。  请问，为何会出现这种情况？ CSn 引脚是否专用于 GPIO？

我对此感到混淆、因为 gpioPinConfigs 数组和枚举不包括 SPI 引脚(或其他外设使用的引脚)。

此外,作品中的另一个扳手是,在我的同事中,惯例是  不使用 BoardGpioInitTable 阵列(除了 PIN_TERMINATE ),所有的引脚配置都在 gpioPinConfigs 阵列中完成。 如果我不使用  BoardGpioInitTable  阵列、应该在哪里对 SPI 引脚进行引脚配置？
