Description: Thermal printer-based parking ticket vending machine
The STEVAL-IPC002V1demonstration board is a
battery-operated hand-held parking ticket vending
machine system with a thermal printer interfaced
with the STM32.
The objective of this demonstration is to generate
and print parking tickets for different types of
vehicles. The system can be easily modified for
other applications that require paper printing
directly from the microcontroller, such as PoSbased
applications, railway/bus ticket printing and
stand-alone printers. Platform: |

Description: 4. I2C程序设计与电路仿真
LPC2138微控制器具有标准的硬件I2C接口，可配置主机或从机，总线时钟频率可调整，可支持400KHZ总线频率。使用I2C总线时，要将P0.2、P0.3连接设置选择SCL、SDA，并且总线上要接两个上拉电阻，阻值1~5千欧。
定义器件的地址和LED输出端口，设置包括从机地址、子地址、数据缓冲区指针、操作数据个数、操作结束标志、子地址使能控制在内的变量。使用PINSEL0、PINSEL1寄存器设置I/O口工作模式，设置LED控制口为输出，其他I/O为输入。将I2C初始化，设置晶振频率，所有通道为IRQ中断，使能I2C中断，写入字节数据写入字节数据，等待周期结束。使用硬件I2C读取数据，在初始地址读出字节数据，若检验读出的数据不正确，读写E2PROM出错报警，闪烁LED报警。
-4. I2C program design and circuit simulation LPC2138 microcontroller with a standard hardware I2C interface, you can configure master or slave, the bus clock frequency is adjustable, can support 400KHZ bus frequency. Using the I2C bus, to P0.2, P0.3 connection settings Select SCL, SDA, and the bus to pick two pull-up resistor, the resistance of 1 to 5 kilohms. Define the address of the device and the LED output port settings include the slave address, subnet address, data buffer pointer, the number of operational data, the operation marks the end of the sub-address enable control, including variables. Use PINSEL0, PINSEL1 register set I/O port mode, set the LED control port as output, other I/O as an input. The I2C initialization, set the crystal frequency, all channels for the IRQ interrupt, I2C interrupt is enabled, the write byte data write byte data, waiting period ends. Using hardware I2C read the data byte read in the initial address data, if the test data read out is not correct Platform: |

Description: Serial data which is transmitted via a RS232 interface is converted to I² C-Bus format. The I² C-Bus is provided from a microcontroller AT89C2051 via software. So it s possible to control I² C-Bus circuits from a PC with low expense. The PC acts as the I² C-Bus master (indirectly via the microcontroller). I² C data can be both written and read, I² C acknowledge bits can be both set and evaluated. Platform: |

Description: 这个是I2C总线的程序，相信学过单片机的同学，应该都知道I2C总线，它是单片机中非常常见的一
个通信总线，且是非常重要的。很多的芯片都使用这种通信协议，比如DS1802温度传感器，DS1302
时钟芯片等都是使用这种通信协议的。所以，同于刚接触单片机的同学，一开始掌握这种通信协议
可能有点难度，所以，这个程序是比较通俗易懂，可以有效帮助您掌握I2C这个总线的控制。-This is the I2C bus procedures, I believe learned SCM students should know I2C bus, it is very common for a single-chip communication bus, and it is very important. Many are using this chip communication protocols, such as a temperature sensor DS1802, DS1302 clock chip, etc. are using this communication protocol. So, with the students in the fourth year of the microcontroller, beginning to master the communication protocol may be a bit difficult, so this procedure is relatively easy to understand, can effectively help you master the I2C control bus.
