大家好,我在这里先给大家做一个自我介绍,我是广东东莞川富科技有限公司的一名初级开发工程师,大学本科学历。去年以前没有接触过单片机,今年年初开始接触Arduino这种小学生以及初中生玩的板子,然后花了一个月觉得我这种板子已经不好玩了,开始学习stm32f407这个开发板。在微控制器上面有了一点点的学习,一路学习之下,在EEWORLD上面看到了下面这个
我就开始申请。
我也算是这方面的小白,让我们一起挖掘Silicon Labs 这块开发板吧。
小弟在这里班门弄斧,献丑了
请各路大神都让开,我要开始装逼了!!!!
一、硬件方面
我看到我的包裹,好大,心想里面肯定还有好多模块。可是我打开后发现
emmm...........................
好吧。
上正题吧
PG22-DK2503A EFM32PG22开发套件,总体来说真的让我特别的意外,这是正点原子的探索者,外观上来说,正点原子比较大,各种外设都是用一些传统的部件,很不舒服
这是我们的PG22-DK2503A EFM32PG22开发套件
外观结构上来说,很小巧,结合了众多功能,重点是每一个集成都特别的小,搭载了最先进的模块.
这让我们新手来说,携带和使用特别的方便,在这里,设计上我要给它点一个大大的👍
让我们看看都有啥???
主要搭载的模块以及我的介绍
- 适用于超低功耗工作场景可以独立控制板载外围设备电源··············纽扣电池供电
- 相对湿度和温度传感器 ························································ 这是外设的传感器,我们用的最多的温湿度传感器是DHT11
- 环境光传感器·······································································这个可以控制灯的开关以及想打开的外设,需要用到串口知识
- 霍尔效应传感器····································································磁场传感器,磁场越强,电压越高,磁场越弱,电压越低
- 6 轴惯性传感器····································································我们常用是6轴的6050型号,这个板子小,搭载不错哦
- PDM 立体声麦克风·······························································PDM这种设计真不错,淘汰了传统的咪头,值得推荐
- 8 MB 串行闪存····································································8 MB相当不错啦,这个整块都不到20美元不到的价格
- 用户 LED 和按钮··································································可以设置点亮LED灯,上下,左右,复位执行
- 20 引脚 2.54 mm 扩展口························································拓展更多的外设,比如心率传感器,音响,加热,LED等等
- SEGGER J-Link 板载调试器···················································就是不用担心再买一个烧录器了,市面上好的烧录器都要100块以上,USB直接下载
- 虚拟 COM 端口····································································虚拟com口,就是可以在设备管理里可以看到,用软件模拟出来的串口,板子上10个引脚
- USB 或纽扣电池供电····························································第一次见纽扣电池开整,想象力丰富。
- Mini Simplicity 连接器,适用于采用外部 Silicon Labs 调试器和虚拟 COM···························就是那条15厘米长的线啦
总结
芯片还没介绍呢
村长你下来,让我说
- ARM Cortex-M33·········································ARM公司设计
- 76.8 MHz
- 达 512 kB 的闪存
- 32 kB RAM
- 27 μA/MHz(活动状态)
- 使用 8 kB 的 RAM EM2 条件下为 1.1 μA
- 0.5 EM4 条件下为 uA w/ RTC
- 2x USART、2x I²C、1x EUART 和 PDM
- 16 位 ADC(16 通道)
- 内置 32 kHz,500 ppm 睡眠 XTAL
- ±2 °C 温度传感器····················································测芯片内部的温度
- -40 至 +125 摄氏度
- 1.71 V 到 3.8 V 单电源·············································供电要求
- 封装:
- 32 引脚 QFN 封装 (4 mm x 4 mm) (18 GPIO)·············GPIO就是引脚
- 40 引脚 QFN 封装 (5 mm x 5 mm) (26 GPIO)

重要的事说三遍!!!
已经给各位老爷们安排上了
你们是不是忘记点赞了???这种事还要我提醒????
按照下图操作
然后就开始下载啦
!!!
点这个.exe安装
注意:请安装再C盘,因为我是win10系统,我安装不成功,安装在C盘才成功的
如有雷同,请注意!!!
对的,这样操作!!!
如果有不认识英文的,比如我,就下载有道翻译官!!拍图翻译。
由于本人安装软件过程中卡了,本次先介绍到这了。
看官老爷们,下期见
