基于ARM Cortex-M4F(TM4C123)单片机 ，编程控制TM4C123微控制器的RTC 模块，实现一个简易的数字时钟，具有多种功能 ?【功能】 ?（1）UART输出当前时间信息，UART可设置日期和时间，设置方法自定； ?（2）可通过UART 设置/查询闹钟，定闹时间到，从UART输出提醒； ?（3）在液晶屏上显示日期和时间信息（中文）； ?（4）可使用实验板上的K1-K4按键修改日期和时间，设置方法自定； ?注：该题依赖于“3”，需先完成“3”才可做该题 ?（5）农历功能，农历自动跟踪阳历的变化； ?（6）24节气功能(Based on ARM Cortex-M4F (TM4C123) MCU, the RTC module of TM4C123 microcontroller is programmed and controlled to realize a simple digital clock, which has many functions. (function) (1) UART output the current time information, UART can set the date and time, set the method to set itself. (2) the alarm clock can be set / inquired by UART, and the time is up until UART is output. (3) display date and time information on LCD screen (Chinese); (4) you can use the K1-K4 button on the experiment board to change the date and time, and set the method to set it. Note: the question depends on "3", and it is necessary to finish "3" first. (5) the function of the lunar calendar, and the lunar calendar automatically tracks the changes of the solar calendar. (6) the function of 24 throttle)

avr + enc28j60仿真及详细使用方法,压缩包内含有源代码及Proteus仿真文件以及仿真方法。(avr+ enc28j60 simulation and detailed use of compressed Proteus package includes source code and simulation files, and simulation methods.)

P1口扩展实验 P1口既做输入口又做输出口，KEY1做为左转弯开关，KEY2做为右转弯开关。LED5、LED6做为左转弯灯，LED7、LED8做为右转弯灯（如图2-2）。 编程实现汽车转向灯功能，即：KEY1接高电平KEY2接低电平时，右转弯灯灭，左转弯灯以一定频率闪烁（注意：KEY拨向上方为0）；KEY2接高电平KEY1接低电平时，左转弯灯灭，右转弯灯以一定频率闪烁；KEY1、KEY2同时接低电平时，发光二极管全灭；KEY1、KEY2同时接高电平时，发光二极管全亮。(P1 I extended not only to do experiments P1 I also do input output, KEY1 switch as a left turn, KEY2 as switches and turn right. LED5, LED6 as a left turn lights, LED7, LED8 as lights and turn right (Figure 2-2). Programming car turn signal function, namely: KEY1 high key2 access low-level access, the right turn lights out, left turn to a certain frequency of flashing lights (Note: KEY allocated to the top to 0) KEY2 access high Key1 low-level access, the left turn lights out, turn right to a certain frequency of flashing lights KEY1, KEY2 low at the same time, the light-emitting diode body KEY1, KEY2 high at the same time, the light-emitting diode light-wide.)

stm32产生spwm程序，利用TIM1和DMA，通过PA8和PB13输出spwm波(stm32 produce spwm program, using TIM1 and DMA, and PB13 through PA8 spwm wave output)
