The technical scheme adopted by the invention for solving the technical problems is as follows:
a single-chip color display method comprises the following steps:
s1: compiling a true color display program, wherein the program comprises 16-bit true color codes, and expressing color pictures and characters through the codes; 16 true color shows effectually to satisfy the daily user demand of text screen, compares simultaneously that 32 true color memory occupy fewly, and is lower to the chip requirement.
S2: writing a program into the color liquid crystal screen through the serial port, and controlling the display of the color liquid crystal screen through the program;
s3: and testing whether the program normally runs, rewriting the program if the program runs wrongly, and finishing if the program is normal.
Preferably, the color liquid crystal panel of step S2 uses a large memory chip such as YK8366S5A or 32M DRAM for storing programs.
Preferably, the serial port in step S2 includes a USB interface or other data downloading interface. The serial port downloading mode downloads programming programs, USB downloading and other downloading modes, so that the product maintenance and updating are more convenient and diversified.
A single-chip color display method is applied to a PLC text screen.
The monochrome text chip in the prior art is 89S55, 2K SRAM or 64K flash, and the working frequency is 12M; the chip used in the method is YK8366S5A or 32M DRAM, the working frequency is 800M, and the price of 89S55 chip plus monochrome liquid crystal is higher than that of the chip YK8366S5A plus SPIflash plus color screen; the cost of the text display screen is reduced, and the display effect is optimized; the color display method of the single chip is applied to a PLC text screen, the PLC can also be placed in YK8366S5A to operate, customers who need to use the PLC and texts at the same time are required, the cost is further reduced, and the PLC does not need to be purchased additionally.
