Description: 12Mhz标准51的100KHz IIC总线主器件模拟方式驱动程序。
本驱动程序即可以在没有Small RTOS的情况下使用。此时，要使用本驱动程序只需要配置IIC总线使用的IO口。在驱动程序的主文件iic_master.c仅包含一个文件config.h。用户需要的是在这个文件中设置IIC总线使用的IO口SDA和SCL。如果用户单独使用iic_master.c，还要在config.h包含iic_master.h文件和其它必须的文件如reg51等；并定义宏TRUE、FALSE和与编译器无关的数据类型。在使用Small RTOS的情况下，用户只要在config.h定义SDA和SCL和包含iic_master.h并将宏IICSem定义为分配给IIC总线驱动程序的信号量的索引。
在使用IIC总线驱动程序前应该调用函数IICInit()初始化IIC总线。单独使用或单任务IIC总线，使用函数IICRead()对IIC总线进行读操作，使用IICWrite()对IIC总线进行写操作。如果有多个任务需要对IIC总线进行操作，则分别调用宏OSIICRead()和OSIICWrite()对其进行读写。-12Mhz standards of 100KHz 51 IIC bus owners device simulation mode driver.

Description: The Inter IC bus or I2C bus is a simple bidirectional two wire bus designed primarily for general control
and data transfer communication between ICs.
Some of the features of the I2C bus are:
• Two signal lines, a serial data line (SDA) and a serial clock line (SCL), and ground are required. A
12V supply line (500mA max.) for powering the peripherals often may be present.
• Each device connected to the bus is software addressable by a unique address and simple
master/ slave relationships exist at all times masters can operate as master-transmitters or as
master-receivers.
• The I2C bus is a true multi-master bus including collision detection and arbitration to prevent data
corruption if two or more masters simultaneously initiate data transfer systems.
• Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 KBit/s in the standard
mode or up to 400 KBit/s in the fast mode.

Description: Siemens PLC功能 ，使用SCL语言编写，与pascal结构类似，完成了个从0-2^31-1的时间计数-this FB is only necessary for siemens sps
the siemens sps timer counts from 0 to 2^31-1 and starts at 0 sfter overrun.
this means that the bit 31 (the highest bit ) will never be used and therefore
a problem arises when t2- t1 is checked.
t2- t1 is always valid also in an timer overrun situation where the time t1 is very high and t2 is very low.
the result of the subtraction t2- t1 however is still valid.
this calculation does not work for soiemens because the highest bit is not used.
this module stores the highest bit, changes the highest bit at every overrun occurence and stuffs ther highest bit in the output.
the output is then used by t_plc_us and t_plc_ms.
the correction needs and fb and not a function because the value of the highest bit has to be stored.
do never use this function block in a codesys environment. the timer in codesys is correct and runs from 0 to 2^32-1

Description: 最近在学习摄像头
想做摄像头采集图像，然后颜色识别，
不过楼主太水
目前只做到可以显示图像
接线：如正点原子ppt图
不过SIOC相当于SCL
SIOD相当于SDA
即，SIOC接PD6
SIOD接PD7
刚打开程序可能kill5会弹出窗口，不用担心关点就可以了
记得调相机焦距
只不过30万像素太低了。。。。(Learning camera recently
Want to be a camera to collect images, and then color recognition.
But the landlord is too water.
At present, we can only display images.
Wiring: ppt diagram of a point atom
But SIOC is equivalent to SCL.
SIOD is equivalent to SDA.
That is, SIOC connects to PD6.
SIOD and PD7
Just open the program, maybe kill5 will pop up the window, don't worry about closing it.
Remember the focal length of the camera.
It's only 300 thousand pixels too low.)
