Valid NV item Id 我设置的是0x201~0xfff之间
void SampleApp_HandleKeys( uint8 shift, uint8 keys )
{
uint8 Txdata[3]={0xAA,0x55,0xAA};
uint8 Rxdata[3]={0};
uint8 Res;
(void)shift; // Intentionally unreferenced parameter
if ( keys & HAL_ASKKEY_SW_1 ) //判断是哪个按键发生 做处理
{
//艾森测试这里让串口打印 P1.7 IS UP 同时改变LED状态
//HalUARTWrite(0,"P1.7 IS UP\n",11 );
HalUARTWrite(0,Txdata,3 );
Res=osal_nv_item_init( USER_NV_ID, 2, NULL );
HalUARTWrite(0,&Res,1 );
#if 0
Res=osal_nv_item_init( USER_NV_ID, 2, NULL );
osal_nv_read( USER_NV_ID, 0, 3, Rxdata );
HalUARTWrite(0,&Res,1 );
HalUARTWrite(0,Rxdata,3 );
uint8 Txdata[3]={0};
HalUARTWrite(0,"\n",1 );
osal_nv_write( USER_NV_ID, 0, 3,Txdata );
osal_nv_read( USER_NV_ID, 0, 3, Rxdata );
HalUARTWrite(0,"\n",1 );
HalUARTWrite(0,Rxdata,3 );
HalUARTWrite(0,"\n",1 );
#endif
}
}
我这里在按键里面做处理，按下就初始化 ，然后先读一次，再写进去，再读出来。但是一直失败，且失败返回都是 09
