上一篇帖子【LPC54114】+ B1.驱动ADS8332+官方库有bug解决了数据采样的问题，这两天又抽空把项目剩下的工作完善了一下。主要是实现了6轴力传感器的数据采集、串口wifi模块发送以及通过板载的数字麦克风进行简单的采样和停止采样的控制。原来的打算是通过语音进行控制的，开始考虑的有点儿简单，调试了两天还是有点儿问题只能等五一过后再搞了。
下来从硬件及软件方面做个总结吧。
1.硬件准备：
LPC54114板卡、I2C接口的oled、6轴力传感器、传感器采集电路、两块CC3200模块。
2.软件准备：
KEIL5.18、SDK2.0、串口工具等。

通过先前对这块板卡的学习，基本的准备工作都差不多了，其实这篇帖子也就是把这些功能组装起来。先来一张效果图吧。
简单的介绍一下，以LPC54114板卡为中心，I2C接口的OLED用于显示，右下角的CC3200模块配置成客户端通过串口连接LPC54114的串口5，右上角的CC3200模块配置成服务器通过USB转串口模块连接电脑。最左边的就是6轴的力传感器包括3轴的力和3轴的力矩，它的6对查分信号通过两级放大以后送到ADS8332进行AD转换然后通过SPI接口和LPC54114进行通讯。板载的数字麦克风进行声音的采集，目前完成的是通过对声音长短的分辨来进行采集的开始和停止。

下边是需要用到的一些IO口的配置：
连接OLED的I2C1接口

i2c_master_config_t masterConfig;
CLOCK_AttachClk(kFRO_HF_to_FLEXCOMM1);
RESET_PeripheralReset(kFC1_RST_SHIFT_RSTn);
IOCON_PinMuxSet(IOCON, 0, 23, 0x181);
IOCON_PinMuxSet(IOCON, 0, 24, 0x181);
I2C_MasterGetDefaultConfig(&masterConfig);
masterConfig.baudRate_Bps = 100000U;
masterConfig.enableMaster = 1;
I2C_MasterInit(I2C1, &masterConfig, 12000000);

复制代码

连接ADS8332的SPI3接口，以及四个普通IO口（三个输出、一个输入）

spi_master_config_t masterConfig = {0};
/* attach 12 MHz clock to SPI3 */
CLOCK_AttachClk(kFRO12M_to_FLEXCOMM3);
/* reset FLEXCOMM for SPI */
RESET_PeripheralReset(kFC3_RST_SHIFT_RSTn);
/* SPI2 pins */
IOCON_PinMuxSet(IOCON, 0, 14, (IOCON_FUNC2 | IOCON_MODE_PULLUP | IOCON_GPIO_MODE | IOCON_DIGITAL_EN)); /* SPI3_CS - FLASH */
IOCON_PinMuxSet(IOCON, 0, 11, (IOCON_FUNC1 | IOCON_MODE_PULLUP | IOCON_GPIO_MODE | IOCON_DIGITAL_EN)); /* SPI3_SCK */
IOCON_PinMuxSet(IOCON, 0, 12, (IOCON_FUNC1 | IOCON_MODE_PULLUP | IOCON_GPIO_MODE | IOCON_DIGITAL_EN)); /* SPI3_MOSI */
IOCON_PinMuxSet(IOCON, 0, 13, (IOCON_FUNC1 | IOCON_MODE_PULLUP | IOCON_GPIO_MODE | IOCON_DIGITAL_EN)); /* SPI3_MISO */
SPI_MasterGetDefaultConfig(&masterConfig);
masterConfig.direction = kSPI_MsbFirst;
masterConfig.polarity = kSPI_ClockPolarityActiveLow;
masterConfig.phase = kSPI_ClockPhaseFirstEdge;
masterConfig.baudRate_Bps = 1000000;
masterConfig.sselNum = (spi_ssel_t)2; // use GPIO as CS is prefer
SPI_MasterInit(SPI3, &masterConfig, CLOCK_GetFreq(kCLOCK_Flexcomm3));
GPIO->DIR[1] &= ~(1U << ADS8332_EOC);
#define ADS8332_EOC 3 //PIO1_3
//
#define ADS8332_CONVST_SET() led_on(0)
#define ADS8332_CONVST_RESET() led_off(0)

复位以后串口0可以看到一下系统打印信息，串口5用于接口传感器数据。

此时程序正在等待中断的产生，当数字麦克风接收到声音的变化进入5次以上10次以下的中断会开始进行数据的采集。

当进入中断的次数大于10又归零而且小于5数据采集停止。

现在语音控制这块儿还是第一次搞，还没有完全弄懂。等五一节之后再好好研究一下吧。
