Then the ISP function of MCU was used to program the MCU once again and plant serial read number program.
利用单片机的IS P功能重新对单片机编程,植入串口读数程序。
The most obvious issue is that the interface in Listing 6 requires a JNI call for each bit set or retrieved, as well as a JNI call to read a byte from, or write a byte to, the serial port.
最显著的一个问题就是,清单6中的接口在设置或检索每个位,以及从串行端口读取字节或者向串行端口写入字节都需要一个JNI调用。
If this happens for you, read the section about configuring the USB serial driver in the Qt Documentation.
如果出现这种情况,请阅读Qt文档中关于如何配置US B串口驱动的一节。
