-**BPS Unit** is a barometer unit, which uses Bosch bmp280 pressure sensor to measure atmospheric pressure and estimate altitude. The relative accuracy can reach ± 0.12hpa, equivalent to ± 1m height difference. At the same time, the temperature drift coefficient is very low, which can reach 1.5 PA / K, that is, the temperature drift is 12.6 cm / K. in addition, there is an integrated temperature sensor in the chip.

 ## Description
 
-**ISO485**  is an isolated half duplex transceiver based on RS485 bus protocol. It can convert TTL level to RS485 level, and various electrical noises and transient changes of voltage and current may appear in the communication link of equipment. Using ca-is3082w as interface chip can effectively shield the above noise and transient, provide sufficient protection for expensive control equipment and reduce the risk of damage. Communication with RS485 equipment at the other end is suitable for long-distance signal transmission. The product has failure protection function. In the receiving state, if the input is open or short circuited, the receiver outputs high level. RS485 is a communication protocol standard, which is used to define the electrical characteristics of drivers and receivers used in serial communication systems. It supports Multipoint Systems and is widely used in industrial fields. When the project equipment needs communication control through RS485 and has high requirements for signal-to-noise ratio and transmission distance, it is a good choice to use iso485 unit for interface type transfer.

+
+## 固件烧录
+
+>1.双击打开Burner烧录工具，①在左侧菜单中选择对应的设备类型，②选择你所需要的固件版本，③点击下载按钮进行下载。
+
+<img src="assets\img\quick_start\core2\burner_m5core01.webp" width="70%">
+
+>2.然后将M5设备通过Type-C数据线连接到电脑，选择对应的COM口，波特率可使用M5Burner中的默认配置，④点击右侧Erase擦除Flash，完成后关闭当前页面。⑤点击"Burn"开始烧录，在烧录时可填入WIFI配置信息。
+
+<img src="assets\img\quick_start\core2\burner_m5core02.webp" width="70%">
+
+>3.当烧录日志提示`Burn Successfully`时，则表示固件已经烧录完成。
+
+<img src="assets\img\quick_start\core2\burner_m5core04.webp" width="70%">
+
+>4. 如果您需要修改配置文件，⑥可点击configuration进行修改。
+
+<img src="assets\img\quick_start\core2\burner_m5core05.webp" width="70%">
+
+
+?>首次烧录或固件程序运行异常时，可点击右上角的"Erase"擦除flash内存，在后续的固件更新时，则无需再次擦除，否则将删除已保存的Wi-Fi信息且刷新API Key.
+
+
+## 配置WIFI
+
+>UIFlow提供了离线与web版本的编程器，在使用web版本的UIFlow时，我们需要为设备配置WiFi连接。下面介绍为设备配置WiFi连接的两种方式（烧录配置与AP热点配置）。
+
+
+### 烧录配置WiFi(推荐)
+
+?>M5Burner支持WiFi连接的前期烧录配置, 用户只需在固件烧录前将WiFi信息填入WiFi配置框，填入的WiFi信息将随同固件一起烧录保存至M5设备。
+
+<img src="assets/img/quick_start/core2/burner_wifi.webp" width="70%">
+
+
+### AP热点配置WiFi
+
+>1.单击设备左侧的电源键开机，屏幕出现UIFlow Logo，等待进入主页面后，按下屏幕上"Setup"按钮。在`WiFi`选项中，按下config Wi-Fi by web选项的start按钮，设备会自动重启，其中Secelt Wi-Fi为上次连接的WiFi。设备跳转后将显示WiFi Config页面，按照提示通过手机或电脑的WiFi连接SSID热点，打开浏览器访问 __192.168.4.1__，在弹出的页面内输入WiFi信息进行配置即可成功配网。配置成功后设备将自动重启。并进入编程模式。
+
+<img src="assets\img\quick_start\core2\core_ap_setup.webp">
+
+?>注意：配置的WiFi信息中，不允许出现"空格"等特殊字符。
+
+<img src="assets\img\getting_started_pics\m5stack_core\get_started_with_uiflow\uiflow_wifi_setup2.webp">
+ 
+
+## 网络编程模式与API KEY
+
+#### 进入网络编程模式
+
+?>网络编程模式是M5设备与UIFlow web编程平台的一个对接模式,屏幕会显示出当前设备的网络连接状态。当页面左上角的WiFi与云端连接指示标志为绿色时，则代表随时可接收程序推送。默认情况下，在首次WiFi网络配置成功后，设备将自动重启，并进入网络编程模式。若您在运行其他应用后不知如何重新进入编程模式，你可以参考以下操作。
+
+>开机后，在屏幕出现菜单后迅速按下屏幕中间Flow按键进入API KEY页面，使用电脑浏览器访问[flow.m5stack.com](http://flow.m5stack.com/)进入UIFlow编程页面.
+
+<img src="assets\img\quick_start\core2\core_wifi_mode.webp">
+
+
+#### API KEY配对
+
+>API KEY是M5设备在使用UIFlow web编程时的通信凭证。通过在UIFlow端配置相应的API KEY，能够为指定的设备推送程序。用户需在电脑端浏览器访问[flow.m5stack.com](http://flow.m5stack.com/)进入UIFlow编程页面，点击页面右上角的菜单栏中的设置按钮，输入对应设备上的API Key，选择使用的硬件，点击OK保存，等待提示连接成功。
+
+<img src="assets/img/quick_start/core2/uiflow_apikey.webp">
+
+## Hello M5
+ 
+>完成以上步骤，就可以开始使用UIFlow进行编程了。（1. 放置标签  2. 添加标签程序块 .3 点击右上角运行按钮 ）

 ## 描述
 
-**BPS** 是一款气压计单元，采用博世BMP280气压传感器，用于测量大气压强与高度估算，相对精度可达到±0.12hPa，相当于±1m的高度差，同时温漂系数相当低，可以达到1.5 Pa/K，即温度漂移为12.6 cm/K，此外在芯片内部还有集成有温度传感器。

 ## 描述
 
-**ISO485** 是一款基于RS485总线协议的隔离式半双工收发器。它可以将TTL电平转换为RS485电平，在设备通信链路中可能出现各种电噪声以及电压电流的瞬态变化，使用CA-IS3082W作为接口芯片可以有效屏蔽以上噪声和瞬变，为昂贵的控制设备提供充分的保护，降低损坏风险。与另外一端的RS485设备进行通讯，适用于信号的长距离传输。该产品具有失效保护功能，在接收状态时，如果输入端开路或短路 则接收器输出高电平。RS485是一种通信协议标准，用于定义用于串行通信系统的驱动器和接收器的电气特性，支持多点系统，广泛应用于工业领域。当项目设备需要通过RS485进行通信控制并且对信噪比及传输距离有较高要求时，使用 ISO485 Unit 进行接口类型转接会是一个不错的选择。
