METHOD FOR CHECKING MEMORY CODE OF PRINTED CIRCUIT BOARD

摘要

Provided is a method for checking a memory code of a printed circuit board. The method comprises: attaching a check code to a tail of code data; after the code data is written into a memory, a timing controller calculating a checksum of main code data; comparing the checksum obtained through calculation with the check code; and outputting, through a test pin, a comparison result to a probe, and displaying the comparison result. The solution is used for checking whether the written code is correct, and can improve the check efficiency of the written code in the memory.
