Can you teach me, recently met a locomotive navigation becomes 1970, each power mp3 player to open the said time wrong, every car to make it a good time, very trouble! Can not to restore power in 1970, such as power outages in 1980 can also! Wince6.0 system (already changed battery)

CodePudding user response:

Code sets the system time, very simple, the key is to make you how will this code is integrated into the system, in the process of start or immediately after the start of call,
Car navigation, tend to have the application of MCU and communication protocol, or application to set their own time, if only the ACC OFF car machine, MCU is no electricity, after startup can protocol synchronization WinCE time; If it is B + off the electricity, will return to a default time, general won't be in 1970, this depends on each machine is how to implement the plan,
