9、H7-TOOL本周进展
H7-TOOL详细介绍：https://www.armbbs.cn/forum.php?mod=viewthread&tid=89934
开始H7-TOOL的2.24版本固件收尾工作，这次更新的内容很多，除了新增一批脱机烧录支持芯片。
这次将带来I2C从机，SPI从机，CANopen解析(已经在论坛发布)，RTOS Trace链表解析，CMSIS-SVD文件解析实时监测各种外设等功能
（1）H7-TOOL的CANopen解析功能增加分包展示心跳，紧急报文，PDO和SDO消息
主从组网测试，节点多了之后，很多消息混杂在一起。今天增加个分窗口展示功能，汇总窗口展示所有消息，其它窗口分别展示心跳，紧急报文，PDO和SDO。
比如下面这种，很多都在一起展示，不好分辩
通过这些窗口做分辩后，会大大方便查看：
同时增加5Mbps通信速度：
（2）H7-TOOL增加CMSIS-SVD解析功能，实时监测所有芯片厂家所有外设寄存器和每个bit
下个2.24版本固件正式发布。
（1）支持离线，WiFi，以太网和USB四种玩法，且支持内网和外网远程访问。芯片所有寄存器状态全部掌控。
（2）不会复位目标板芯片，随时连接随时使用。
（3）MDK, IAR等在线调试有两个重要功能，一个是断点，单步调试等玩法。还有一个就是外设寄存器状态，内存数据等实时检测。我们本次要实现的是后者，当前TOOL就可以读写外设寄存器，但是需要看IC数据手册来获取外设地址，非常不方便。
针对这个问题，IC厂家都有推出CMSIS-SVD文件，这个文件包含了所有外设寄存器地址，甚至每个寄存器每个bit的含义。所以TOOL能够解析这个文件，意义重大。
初步上位机解析效果：
之前版本已经发布了elf，axf，out可执行文件解析
这样内存变量解析，寄存器解析全部集齐
