Since this command system and lcd display drive controller compatible

Software programming language using Keil C51 driver includes a display module hardware (ie write commands and write data), and clear screen display module initialization routines as well as other common Western character display realization process. Since this command system and lcd display
 drive controller  compatible, so these procedures have a high versatility. For character character display COG LCD Displaycharacter features of the module library data is prepared in the form of columns of data that a byte of data represents the data of an 8 × 1, and compared with the usual character library, the character is rotated by 90 ° font data. Use Zimo21.exe take matrix software, and set the mode to portrait modulo Coding System lcd module extraction, you can easily obtain the necessary Western text mode. Since each column of data to the display module 8 × 1 is the low front, high in the post, in order to further achieve the correct display of Chinese and Western culture, the need for each byte matrix obtained by the above method to conduct a swap of high and low , the program uses an array UpsetChar  to achieve. Western character used in the program is 16 × 8 dot matrix, character is a 16 × 16 dot matrix.
