Should I use a F103 or F4 to drive dual motor? Whice one is a better choice? Why the MCSDK v5.4.3 in dual motor app;ication do not support the F103 serials chip, but MCSDK v4.3 do support? 如果想设计一款�?�路驱动，主控芯片应该选用F103还是F4系列？哪一个更好？
So as the title. I'm going to design a motor drive which can drive two motor. (Seems like Odrive). Inorder to reduce the cost, I want to use the F103 as my MCU.
如题所示，我想�?设计一款�?�路电机驱动。（有点类似开�?电机驱动Odrive）。为了节约�?本，我希望使用STM32F103作为我的MCU。
First time I planned to use the MCSDK v4.3 to design my motor driver, and luckly it support F103 in dual motor application. (The chip choosed list showed )
刚开始，我计划使用MCSDK v4.3去设计我的电机驱动，�?�常幸�?，MCSDK v4.3的dual motor模�?支�?F103（在它的芯片选择列表里�?�以找到F103）
After while, I got a new idea——"the newest MCSDK may have fewer bugs as the ST had improved it", so I dowloaded the newest version MCSDK v5.4.3 and found that it's dual motor model do not support F103 in dual motor application. (can't find F103 in chip choosed list )
过了一会儿，我有了一个新的想法——“最新版本的MCSDK应该会有更少的错误，因为ST公�?��?�级了版本，完善了它�?，所以我下载了最新的版本MCSDK v5.4.3，然�?��?�现它的dual motor模�?�?支�?F103。（在它的芯片选择列表里找�?到F103）
Then I'm puzzled. That's why I'm here.
如此令人困惑，所以我�?�到了这里（论�?�）
Flow is my question:
- Should I use a F103 or F4 to drive dual motor? Whice one is a better choice?
- Why the MCSDK v5.4.3 in dual motor application do not support the F103 serials chip, but MCSDK v4.3 do support?
- Why did ST company cancel support for F103 in the dual motor mode of MCSDK v5.4.3? (It was originally supported in v4.3?)
- Is there any document of website can I find the difference between v5.4.3 or v4.3?
Please give me some clues.
以下是我的问题：
- 我应该使用F103还是F4作为�?�路驱动�?�的MCU？哪一个选择更好？
- 为什么 MCSDK v5.4.3的�?�电机模�?（dual motor model）�?支�?F103而MCSDK v4.3支�?？
- ST公�?�是出于什么原因，让MCSDK v5.4.3的�?�电机模�?�?�消支�?F103？（原本在v4.3中是支�?的？）
- 我在哪里�?�以找到有关v5.4.3和v4.3差别的资料�?文档�?或者网站？
请给我一些线索
As the Odrive used F405 as it's dual motor driver's MCU, should I use an F4 too?
开�?电机驱动�?�Odrive使用了F405作为其�?�路电机驱动�?�的MCU，所以我也应该选择使用F4?
