【WaRP7试用体验】5.WaRP7开发板自带WIFI功能验证和MPL3115A2模块功能验证

开发板

` 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。

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

#!/bin/sh
#WaRP7 Wi-Fi Enablement Script
FILE=/lib/modules/$(uname -r)/kernel/drivers/net/wireless/bcmdhd/bcmdhd.ko
if [ -f $FILE ];
then
modprobe bcmdhd
ifconfig wlan0 up
echo "Enter the network name (SSID)"
read SSID
echo "Type the passphrase for the network and hit enter"
read PSW
wpa_passphrase $SSID $PSW > /etc/wpa_supplicant.conf
cat /etc/wpasupplicant.conf
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf -D nl80211 &
wait
udhcpc -i wlan0
echo "You can now use the ping command to test your connection"
else
echo "bcmdhd.ko module file not found"
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。

同样有可以测试的脚本
