9、H7-TOOL本週進展
H7-TOOL詳細介紹：https://www.armbbs.cn/forum.php?mod=viewthread&tid=89934
開始H7-TOOL的2.24版本固件收尾工作，這次更新的內容很多，除了新增一批脫機燒錄支持芯片。
這次將帶來I2C從機，SPI從機，CANopen解析(已經在論壇發佈)，RTOS Trace鏈表解析，CMSIS-SVD文件解析實時監測各種外設等功能
（1）H7-TOOL的CANopen解析功能增加分包展示心跳，緊急報文，PDO和SDO消息
主從組網測試，節點多了之後，很多消息混雜在一起。今天增加個分窗口展示功能，彙總窗口展示所有消息，其它窗口分別展示心跳，緊急報文，PDO和SDO。
比如下面這種，很多都在一起展示，不好分辯
通過這些窗口做分辯後，會大大方便查看：
同時增加5Mbps通信速度：
（2）H7-TOOL增加CMSIS-SVD解析功能，實時監測所有芯片廠家所有外設寄存器和每個bit
下個2.24版本固件正式發佈。
（1）支持離線，WiFi，以太網和USB四種玩法，且支持內網和外網遠程訪問。芯片所有寄存器狀態全部掌控。
（2）不會復位目標板芯片，隨時連接隨時使用。
（3）MDK, IAR等在線調試有兩個重要功能，一個是斷點，單步調試等玩法。還有一個就是外設寄存器狀態，內存數據等實時檢測。我們本次要實現的是後者，當前TOOL就可以讀寫外設寄存器，但是需要看IC數據手冊來獲取外設地址，非常不方便。
針對這個問題，IC廠家都有推出CMSIS-SVD文件，這個文件包含了所有外設寄存器地址，甚至每個寄存器每個bit的含義。所以TOOL能夠解析這個文件，意義重大。
初步上位機解析效果：
之前版本已經發布了elf，axf，out可執行文件解析
這樣內存變量解析，寄存器解析全部集齊
