你好：
我想使用SRR的範例增加GPIO控制，用來顯示燈號
目前我的作法是在MSS裡的SRR_MSS_initTask增加腳位定義，代碼如下:
Pinmux_Set_OverrideCtrl(SOC_XWR16XX_PINJ13_PADAC, PINMUX_OUTEN_RETAIN_HW_CTRL, PINMUX_INPEN_RETAIN_HW_CTRL);
Pinmux_Set_FuncSel(SOC_XWR16XX_PINJ13_PADAC, SOC_XWR16XX_PINJ13_PADAC_GPIO_1);
Pinmux_Set_OverrideCtrl(SOC_XWR16XX_PINK13_PADAZ, PINMUX_OUTEN_RETAIN_HW_CTRL, PINMUX_INPEN_RETAIN_HW_CTRL);
Pinmux_Set_FuncSel(SOC_XWR16XX_PINK13_PADAZ, SOC_XWR16XX_PINK13_PADAZ_GPIO_2);
GPIO_setConfig (SOC_XWR16XX_GPIO_1, GPIO_CFG_OUTPUT);
GPIO_setConfig (SOC_XWR16XX_GPIO_2, GPIO_CFG_OUTPUT);
static void SRR_MSS_initTask (UArg arg0, UArg arg1)
{
int32_t errCode;
MMWave_InitCfg initCfg;
UART_Params uartParams;
Task_Params taskParams;
SOC_SysIntListenerCfg listenerCfg;
Semaphore_Params semParams;
Mailbox_Config mboxCfg;
/* Debug Message: */
System_printf("Debug: Launched the Initialization Task\n");
