There is need of cyclical reading (lower than 1 minute periods) of the actual values from the real-time clock and the sensors for pressure and temperature,and to store the read values into the microcontroller’s memory.The communication with the real-time clock and the sensors is possible with the use of I2C interface and the previously defined in the specifications protocols for reading and writing.
There is need too the read values to be converted in the appropriate format before their actual visualization.For that purpose the filling with zeroes and ones is done of the three previously defined pixel tables.Every cell from these tables corresponds to one pixel from the LED matrix for the visualization of the three kinds of information,and the value into the cells determines the state of the pixels – turn off or turn on.
The refresh frequency of the information over the LED Display is chosen to be 100 Hz to achieving the more stable display image without flickering and blinking.In this situation the refreshing of the visualized information is reduced to cyclically selecting of one of the 48 columns every 200 μs (5 kHz) and it’s reloading with the values from the corresponding pixel table which is chosen.

需要周期性实时读取时间和压力、温度传感器的读数,将数值存储到微控制器的存储器中.使用I2C人机界面和先前规格协议中定义的读写知识,完成上述读取和存储的过程是完全可行的.在成为具体可视的形式之前,读取出来的数值要经过适当的格式转换.为此,像素表中首先填入0或1,表中每一个格子都对应LED矩阵中的一个像素以使三种数值可视化,格子中的值决定了像素的状态——关闭或打开.为了达到最好的图像效果LED显示器的信息刷新频率规定为100Hz.在这种情况下,可视信息的刷新频率降低,每200 μs (5 kHz)选择一48个格子中的一个,并配以对应像素表中的值.
