ABB PM856 3BSE018104R1 AC 800米处理器模块

PM856 3BSE018104R1 treats 4 individual 5×7 matrix LEDs as 4 character numbers. The user controls which of the 104 fixed characters and 24 user-defined characters to display for each number. If necessary, users can load custom characters into 24 user-defined fonts after power on. Use a number register to select a character from a 128 character font to control the display. This method is fast and effective for character display, but not suitable for graphic display.

For graphic applications using MAX6952 or PM856 3BSE018104R1, the control technology is the opposite. Fixed fonts are ignored, and 24 user-defined fonts are used for direct graphic display control. Each digital register is set to point to a different user-defined font position, and the font itself is manipulated to adjust the graphic display in the 5 * 7 section. If flicker control is not required, only 4 user-defined font positions are needed, one for each 5 * 7 section (Table 1). If using flicker, 8 user-defined font positions are required, with one position for each flicker stage (P1 and P0) in each 5×7 section (Table 2). The number register only needs to be written once with the appropriate RAMxx character address, and the font itself is manipulated to set the graphic image.
