[Other] 24C04 DL : 0: 此实验程序向24C04的第0单元写入数据“5”，以检验24C04的读写功能，然后读出刚才写入的数据，如果读出的数据和写入的数据相同，说明存储成功；反之，如果读出的数据和写入的不同，说明存储失败，如果能够对24C04正常读写，则P1.7的绿灯点亮，如果24C04的读写失败，则P1.6的红灯点亮，表示24C04不存在或损坏，注意：不要长时间运行此程序，因为程序会快速反复擦写00H单元，以免擦写次数超过存储单元的使用次数而造成00H单元损坏，正常时候，P1.7绿灯点亮，要观察效果，可以拔下P1.0的跳线即可-This experimental procedure to 24C04 the first 0 unit write data " 5" , in order to test 24C04 of the read and write capabilities, and then read the data just written, if the data read and write data on the same show store successful the other hand If the data read and write different, indicating memory failure, if we can read and write to the 24C04 to normal, then the P1.7 of the green light, if the reading and writing 24C04 fails, then the red light lit P1.6, that 24C04 does not exist or damaged, pay attention: Do not run this program a long time because the program will quickly erase repeatedly 00H unit, so as not to erase the memory cell number than the frequency of use 00H cell damage caused by the normal time, P1.7 green points Liang, to observe the effects, you can unplug the jumper can be P1.0
