Realtime clock and motor controler 16f877A

说明：  尽管模拟高频头在开发中用得已经减少了，但是模拟电视接收功能在许多数码产品上仍有其身影。希望对本站的朋友有所帮组！(Although the analog tuner in the development of using has been reduced, but the analog TV reception capabilities in a number of digital products still has its shadow. Want to site a friend had to help group!)

典型PID算法程序，经实验，控制效果优，控制精度高。(It is a representative program of PID arithmetic.The effect of control is excellent and the precision of control is high via experiment.)

MSC121X例程rtc wd spi eeprom (MSC121X_examples code)

说明：  AVR单片机做的数字示波表的双机通信程序，可以实现双机见SPI通信，M16做的(AVR microcontroller to do the Dual Digital Oscilloscope communication program, you can achieve double see SPI communication, M16 do)

Micrium_STM32L152-EVAL_uCOS-III STM32L系列的uCOS-III移植，官方Demo，很好，很强大 (Micrium_STM32L152-EVAL_uCOS-III STM32L series of uCOS-III transplant, the official Demo, very good, very strong)
