5.WaRP7开发板自带WIFI功能验证和MPL3115A2模块功能验证

时间：10-02 整理：3721RD 点击：
  根据下图我们知道WaRP7有一个自带WIFI模块。接过多方查找终于找到了WIFI的名字LBEE5KL1DX。



  下面是尝试如何加载驱动。最简单的方式是按照文档User_Guide_Manual_v1-3.pdf说明更换新的Yocto项目。
  

  1. $ mkdir ~/bin
  2. $ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
  3. $ chmod a+x ~/bin/repo
  4. $ PATH=${PATH}:~/bin
  5. $ mkdir fsl-community-bsp
  6. $ cd fsl-community-bsp
  7. $ repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b krogoth
  8. $ repo sync

复制代码

经过差不多8个小时下载，编译，然后开发板将新的系统固件跑起来。从网上找到一个使能WIFI的脚本程序，https://github.com/WaRP7/warp7-unit-test/blob/master/unit_test/Wifi_BCM4343_enable.sh

  1. #！/bin/sh
  2. #WaRP7 Wi-Fi Enablement Script
  3. FILE=/lib/modules/$(uname -r)/kernel/drivers/net/wireless/bcmdhd/bcmdhd.ko
  4. if [ -f $FILE ];
  5. then
  6.         modprobe bcmdhd
  7.         ifconfig wlan0 up
  8.         echo "Enter the network name (SSID)"
  9.         read SSID
  10.         echo "Type the passphrase for the network and hit enter"
  11.         read PSW
  12.         wpa_passphrase $SSID $PSW  > /etc/wpa_supplicant.conf
  13.         cat /etc/wpasupplicant.conf
  14.         wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf -D nl80211 &
  15.         wait
  16.         udhcpc -i wlan0
  17.         echo "You can now use the ping command to test your connection"
  18. else
  19.         echo "bcmdhd.ko module file not found"
  20. fi

  Xtrinsic MPL3115A2使用一MEMS压力传感器, 带有I2C接口, 可提供精准的电压/高度和温度数据. 这一传感器为数字化输出, 使用一个高分辨率的24位模数转换器. 内部处理省去了主控MCU系统的补偿任务. 另有多个可用户编程, 电源节约, 中断和自治数据采集模式, 包括已编程的采集周期计时器和只轮询模式. 典型电源电流为40μA每测量-秒, 用于稳定的10cm输出分辨率.具体一下特点：
内部完全补偿；可编程事件；自治数据采集；分辨率降至0.1m；32个采样FIFO；可使用FIFO记录多达12天的数据
1秒到9小时数据采集速率；I2C数字输出接口；
应用领域：消费电子产品, 传感与仪器, 系统监控, 机器人。

因为驱动只暴露了最简单的sys接口，只要我们搞清楚0x60是这个模块在这个开发板的iic地址，0xc4是其设备ID。0x1，0x2，0x3，0x4，0x5分别代表什么意思即可。
