用STM32F103C8T6去读取JY901的串口数据

supergiant

1 简述
      想做一个能观察我的VGA小车的姿态角度的系统，一直在网上找相对应的模块。想找个性价比高点的，同时精度高点的。最后在淘宝上找到一款JY901模块。这个模块能XY动态精度0.1度，静态能到0.05度。Z轴的精度为1度。一般一百多元的价格，能到这个精度的还是很少的。果断入手一个来测试下性能。下图给大家看下这个模块





模块的体积很小，很方便能贴在我的PCB板上。不过这个模块的Z轴不能受磁场干扰。因此只能远离我的VGA小车的电机，我把这个模块和我的板子一起用杆子撑起来，远离这些干扰（我是做的一根30CM的杆）。最后测试效果还可以的。

2 连接方式
这个JY901连接是很方便的。供电3.3-5v。直接接我单片机上电压就行了。接线的方式如下：





3 串口读取程序
串口读取简单分为两个部分。1、配置单片机的UART口。2、数据处理部分了。下面和大家一一分享。

3.1配置单片机的UART口
我使用的是UART2，使用时钟、模式、速度等。都在下面大家参考下

[backcolor=inherit !important]void [backcolor=inherit !important]Initial_UART2[backcolor=inherit !important]([backcolor=inherit !important]unsigned [backcolor=inherit !important]long baudrate[backcolor=inherit !important])[backcolor=inherit !important]{         GPIO_InitTypeDef GPIO_InitStructure[backcolor=inherit !important];        USART_InitTypeDef USART_InitStructure[backcolor=inherit !important];        NVIC_InitTypeDef NVIC_InitStructure[backcolor=inherit !important];         [backcolor=inherit !important]RCC_APB1PeriphClockCmd[backcolor=inherit !important](RCC_APB1Periph_USART2 | RCC_APB2Periph_GPIOA[backcolor=inherit !important], ENABLE[backcolor=inherit !important])[backcolor=inherit !important];        GPIO_InitStructure[backcolor=inherit !important].GPIO_Pin = GPIO_Pin_2[backcolor=inherit !important];        GPIO_InitStructure[backcolor=inherit !important].GPIO_Mode = GPIO_Mode_AF_PP[backcolor=inherit !important];        GPIO_InitStructure[backcolor=inherit !important].GPIO_Speed = GPIO_Speed_50MHz[backcolor=inherit !important];        [backcolor=inherit !important]GPIO_Init[backcolor=inherit !important](GPIOA[backcolor=inherit !important], &GPIO_InitStructure[backcolor=inherit !important])[backcolor=inherit !important];            GPIO_InitStructure[backcolor=inherit !important].GPIO_Pin = GPIO_Pin_3[backcolor=inherit !important];        GPIO_InitStructure[backcolor=inherit !important].GPIO_Mode = GPIO_Mode_IN_FLOATING[backcolor=inherit !important];        [backcolor=inherit !important]GPIO_Init[backcolor=inherit !important](GPIOA[backcolor=inherit !important], &GPIO_InitStructure[backcolor=inherit !important])[backcolor=inherit !important];                 USART_InitStructure[backcolor=inherit !important].USART_BaudRate = baudrate[backcolor=inherit !important];        USART_InitStructure[backcolor=inherit !important].USART_WordLength = USART_WordLength_8b[backcolor=inherit !important];        USART_InitStructure[backcolor=inherit !important].USART_StopBits = USART_StopBits_1[backcolor=inherit !important];        USART_InitStructure[backcolor=inherit !important].USART_Parity = USART_Parity_No [backcolor=inherit !important];        USART_InitStructure[backcolor=inherit !important].USART_HardwareFlowControl = USART_HardwareFlowControl_None[backcolor=inherit !important];        USART_InitStructure[backcolor=inherit !important].USART_Mode = USART_Mode_Rx | USART_Mode_Tx[backcolor=inherit !important];        [backcolor=inherit !important]USART_Init[backcolor=inherit !important](USART2[backcolor=inherit !important], &USART_InitStructure[backcolor=inherit !important])[backcolor=inherit !important];         [backcolor=inherit !important]USART_ITConfig[backcolor=inherit !important](USART2[backcolor=inherit !important], USART_IT_TXE[backcolor=inherit !important], DISABLE[backcolor=inherit !important])[backcolor=inherit !important];            [backcolor=inherit !important]USART_ITConfig[backcolor=inherit !important](USART2[backcolor=inherit !important], USART_IT_RXNE[backcolor=inherit !important], ENABLE[backcolor=inherit !important])[backcolor=inherit !important];                [backcolor=inherit !important]USART_ClearFlag[backcolor=inherit !important](USART2[backcolor=inherit !important],USART_FLAG_TC[backcolor=inherit !important])[backcolor=inherit !important];                [backcolor=inherit !important]USART_Cmd[backcolor=inherit !important](USART2[backcolor=inherit !important], ENABLE[backcolor=inherit !important])[backcolor=inherit !important];        NVIC_InitStructure[backcolor=inherit !important].NVIC_IRQChannel = USART2_IRQn[backcolor=inherit !important];        NVIC_InitStructure[backcolor=inherit !important].NVIC_IRQChannelPreemptionPriority = [backcolor=inherit !important]1[backcolor=inherit !important];        NVIC_InitStructure[backcolor=inherit !important].NVIC_IRQChannelSubPriority = [backcolor=inherit !important]8[backcolor=inherit !important];        NVIC_InitStructure[backcolor=inherit !important].NVIC_IRQChannelCmd = ENABLE[backcolor=inherit !important];        [backcolor=inherit !important]NVIC_Init[backcolor=inherit !important](&NVIC_InitStructure[backcolor=inherit !important])[backcolor=inherit !important];[backcolor=inherit !important]}
3.2 数据处理
3.2.1数据接收
    编写思维是这样的。当我的UART2接受到数据后就会存在我的ucRxBuffer[250]里，根据这个JY901的通讯协议。我就开始判断我接受的数据里面是不是有55包头的数据。然后我还加了一个计数ucRxCnt。加在一起我会判断。整个数据的长度是不是11位数据。最后，根据商家给的通讯协议里。50代表时间、51加速度、52角速度、53角度、54磁场等，我再判断我的这11位数据的第二位是上面的哪个值。就可以了。
