kingview and 51MCU ASCII send and recieve 组态王与51单片机通信ASCII(kingview and 51MCU ASCII send and recieve)

自行车的里程表。基于51单片单片机最小系统开发的(The bike' s odometer. Developed based on 51 single-chip microcontroller minimum system)

说明：  用stm32f103c8t6做了一个智能台灯(Make an intelligent desk lamp with stm32f103c8t6)

STM8的IAR工程，使用官方库文件，ST-Link仿真器(STM8，Demo Template in IAR)

采用MSP430G2553和12864液晶实现控制界面，可控制端口输出不同频率的脉冲波形，同时还可测量不同信号的电压值(12864 achieved using MSP430G2553 and control interface, you can control the port output pulse waveforms of different frequencies, but can also measure the voltage values ​ ​ of different signals)

OLED显示屏测试，基于IIC通讯，供电3.3V或5V(OLED screen display demo)

STM32单片机的PID算法实例，通过PID算法控制STM32的PWM输出，反馈量是PWM低通滤波后得到的AD(STM32 microcontroller PID algorithm instance, through the STM32 PID algorithm to control the PWM output, PWM amount of feedback is obtained after low-pass filter AD)

编写程序，通过8255 单元控制点阵的扫描显示，使8×8LED 点阵到小循环显示号 “□”(Programming, through the 8255 unit control the scanning dot matrix display, the 8 × 8LED dot matrix display number to small cycles " □" )

将每2片74595做级联，然后再将级联之后的所有时钟线与数据再并联在一起最后对每一组的锁存控制线做单独控制.(Application to do a project, the more I/O, applied to the 74,595 to do the extension, but you want to mount multi-chip 74595, is bound to have a lot to use the I/O port, in order to solve this problem, I will be every 2 sheet 74595 do cascade, and then cascade after all the clock line and the data in parallel and then together (i.e., all 74595 communal clock and data lines, it only occupies two I/O port lines) Finally, for each group latch control lines do individually controlled (equivalent to Chip Select), so that a hardware circuit by a great degree of simplification, both procedures can also share a driving subroutine 74595, to control the type of lock inventory control line, serial data is sent to the port 74595 cascade module. As a result of the hardware and software have a large degree of optimization.)
