CH375B用在430单片机上，做主机，使用网站提供的FILELIBF_V41下的库，链接后出现下列错误，请教该如何处理：我用的IAR是V4.21.2 Building configuration: USB - Debug Updating build tree... main.c Linking Warning[w6]: Type conflict for external/entry "mCmdParam", in module CH375MAI against external/entry in module main;

似乎并不影响使用，已经调通了。 不清楚这两个参数类型冲突和参数定义过多是怎么回事，总有种不放心的感觉！

这个警告没有任何影响，放心使用
