Part Number:CC3235S
尊敬的TI工程师您好
我是LAUNCHXL-CC3235S,我烧录的使out of box 例程,我在代码中设置了断点,经编译查看,读出的加速度x轴数据、加速度y轴数据、加速度z轴数据为什么都是-1呢?
Nick Sun:
您好,
您SDK版本是多少?
,
hui li:
simplelink_cc32xx_sdk_5_20_00_06。 我是想在linklocalTask的线程中,通过串口打印的形式把加速度数据和温度数据打印出来, 刚才试了试,串口打印出来的加速度数据不管是x轴、y轴、z轴都是-1,温度数据都是0。 我也不确定问题出在哪里?

Nick Sun:
您好,
能把你相应修改部分的程序发过来我们测试一下吗(编辑栏插入—代码)?

hui li:
我只是把out of box例程的link_local_task.c文件有调整。
调整的地方有:
void * linkLocalTask(void *pvParameters) {mq_attr attr;int32_t msgqRetVal;I2C_Params i2cParams;uint8_tabb;uint8_tabc;char tempStr[8];char tempStre[8];int8_t xValRead, yValRead, zValRead;int16_t value = 0;int16_t valueee = 0;float fTempRead;/* initializes I2C */I2C_Params_init(&i2cParams);i2cParams.bitRate = I2C_400kHz;i2cHandle = I2C_open(CONFIG_I2C_0, &i2cParams);if(i2cHandle == NULL){UART_PRINT("[Link local task] Error Initializing I2C\n\r");}/* Setup mutex operations for sensors reading */sensorLockObj = malloc(sizeof(pthread_mutex_t));if(sensorLockObj == NULL){UART_PRINT("[Link local task] could not Setup mutex operations for sensors reading\n\r");while(1){;}}pthread_mutex_init(sensorLockObj, (pthread_mutexattr_t*)NULL);UART_PRINT("aaaaaaaaaaaaaa\n\r");abb=accelarometerReading();if(abb != 0)/* leave previous values */{UART_PRINT("nnnnnnnnnnnnnnnnn\n\r");}else{value =yValRead ;itoa(yValRead, tempStr);//把整形转字符型函数UART_PRINT(tempStr,8);//打印字符函数}#if 0abc=temperatureReading();if(abc != 0)/* leave previous values */{UART_PRINT("nnnnnnnnnnnnnnnnnnnnnnnnnnn\n\r");}else{valueee =(int)fTempRead ;itoa((int)fTempRead, tempStre);//把整形转字符型函数UART_PRINT(tempStre,8);//打印字符函数} #endif/* initializes mailbox for http messages */attr.mq_maxmsg = 10;/* queue size */attr.mq_msgsize = sizeof(SlNetAppRequest_t*);/* Size of message */linkLocalMQueue = mq_open("linklocal msg q", O_CREAT, 0, &attr);if(((int)linkLocalMQueue) <= 0){UART_PRINT("[Link local task] could not create msg queue\n\r");while(1){;}}initLinkLocalDB();/* waits for valid local connection - via provisioning task*/sem_wait(&Provisioning_ControlBlock.provisioningDoneSignal);while(1){SlNetAppRequest_t *netAppRequest;msgqRetVal =mq_receive(linkLocalMQueue, (char *)&netAppRequest,sizeof(SlNetAppRequest_t*), NULL);if(msgqRetVal < 0){UART_PRINT("[Link local task] could not receive element from msg \queue\n\r");while(1){;}}INFO_PRINT("[Link local task] NetApp Request Received - handle from main ""context AppId = %d, Type = %d, Handle = %d\n\r",netAppRequest->AppId, netAppRequest->Type, netAppRequest->Handle);INFO_PRINT("[Link local task] Metadata len = %d\n\r",netAppRequest->requestData.MetadataLen);if((netAppRequest->Type == SL_NETAPP_REQUEST_HTTP_GET) ||(netAppRequest->Type == SL_NETAPP_REQUEST_HTTP_DELETE)){if(netAppRequest->Type == SL_NETAPP_REQUEST_HTTP_GET){UART_PRINT("[Link local task] HTTP GET Request\n\r");}else{UART_PRINT("[Link local task] HTTP DELETE Request\n\r");}httpGetHandler(netAppRequest);}else if((netAppRequest->Type == SL_NETAPP_REQUEST_HTTP_POST) ||(netAppRequest->Type == SL_NETAPP_REQUEST_HTTP_PUT)){if(netAppRequest->Type == SL_NETAPP_REQUEST_HTTP_POST){UART_PRINT("[Link local task] HTTP POST Request\n\r");}else{UART_PRINT("[Link local task] HTTP PUT Request\n\r");}INFO_PRINT("[Link local task] Data received, len = %d, flags= %x\n\r",netAppRequest->requestData.PayloadLen,netAppRequest->requestData.Flags);httpPostHandler(netAppRequest);}if(netAppRequest->requestData.MetadataLen > 0){free (netAppRequest->requestData.pMetadata);}if(netAppRequest->requestData.PayloadLen > 0){free (netAppRequest->requestData.pPayload);}free (netAppRequest);} }static void reverse(char s[]) {int i, j;char c;for (i = 0, j = strlen(s)-1; i<j; i++, j--) {c = s[i];s[i] = s[j];s[j] = c;} }static void itoa(int n, char s[]) {int i, sign;if ((sign = n) < 0)/* record sign */n = -n;/* make n positive */i = 0;do {/* generate digits in reverse order */s[i++] = n % 10 + '0';/* get next digit */} while ((n /= 10) > 0);/* delete it */if (sign < 0)s[i++] = '-';s[i] = '\0';reverse(s); }注意,在link_local_task.c文件的前面要对两个函数定义下:
static void itoa(int n,char s[]); static void reverse(char s[]);程序烧进去后,某一个姿态数据 和 温度分别为 -1、 0,不知道问题出在哪里?

Nick Sun:
您好,
感谢您的对TI产品的关注!为更加有效地解决您的问题,我需要多一些时间查看这个问题,稍后会为您解答。

Nick Sun:
您好,
您的加速度计的值-1在移动设备的时候会改变吗?
您可以参考如下帖子可能会有所帮助:链接

Nick您好,
我也移动了开发板,同时也用手捂住了温度传感器,串口打印出来的加速度值还是-1、温度值还是0,
在void * linkLocalTask(void *pvParameters)函数中,
我明明调用了abb=accelarometerReading();
和abc= temperatureReading();
并立马串口打印,打印出来的值分别是 -1 和 0,
我在找找原因。
同时我研究研究这个链接,多谢啦
