CC2538 GPIO控制LED灯遇到奇怪问题

chao sun3

我用的zmesh-1.0.0，我有2个led接在了PC2,pc3上，分别对应HAL_LED_3和HAL_LED_4

经过单步跟踪调试发现：

uint8 ZMacReset( uint8 SetDefaultPIB )
{
byte stat;
byte value;
GPIODirModeSet(BSP_LED_BASE, BSP_LED_ALL, GPIO_DIR_MODE_OUT);
GPIOPinTypeGPIOOutput(BSP_LED_BASE, BSP_LED_ALL);
HalLedSet (HAL_LED_3, HAL_LED_MODE_ON);
HalLedSet (HAL_LED_4, HAL_LED_MODE_ON);
HalLedSet (HAL_LED_3, HAL_LED_MODE_OFF);
HalLedSet (HAL_LED_4, HAL_LED_MODE_OFF);

stat = MAC_MlmeResetReq( SetDefaultPIB );

GPIODirModeSet(BSP_LED_BASE, BSP_LED_ALL, GPIO_DIR_MODE_OUT);
GPIOPinTypeGPIOOutput(BSP_LED_BASE, BSP_LED_ALL);
HalLedSet (HAL_LED_3, HAL_LED_MODE_ON);
HalLedSet (HAL_LED_4, HAL_LED_MODE_ON);
HalLedSet (HAL_LED_3, HAL_LED_MODE_OFF);
HalLedSet (HAL_LED_4, HAL_LED_MODE_OFF);
