C51 use the source control PLL (SANYO LC72131) radio, Driving through HT1621 LCD Display, a complete module button control procedures, KEY through various functional operation, the whole process has a modular design and facilitate transplantation, beginners can use and reference. (which is also before I posted, how never opened)
