Speed is 1, the speed is faster, but the display is normal, there will be no ghosting phenomenon, when speed is 2, 3 and 4, the speed is slow, but there will be ghosting phenomenon, what is the reason ah? Solving? The following is a scan display module program #include<STC12C5A32S2.h> #include _nop_ ("intrins.h"); / / call delay function with #include i...
Set breakpoints to see if there is any logical error in that function, and it is the best way to help you debug through the build environment
First, send data to the 595 mile, but not latch (do not give the SRCLK pulse), this time the normal display of the original dataNext, the 138EN is set low to turn off the display595 latch (giving the SRCLK pulse) output138ABC update display position, EN set high, open displaySo there will be no ghosting. If so, it shows that the device is slow, and proper early warning is displayed
Ghosting problem in the program, but it does not seem to give the whole program, not good judgment.
