#144114 - HD44780 4X20 to 2 2x20 LCD. |
Sorry for English lang. spartan
Hai all, Had HD44780 4x20 LCD. Want to using it with two AT89S52 as two display of AT89S52s 2x20. After get manual pdf document of HD44780.the document didn't describe how to separate 4X20 LCD became 2 2x20 LCDs operation. How's about using MC4066 switch or MUX for Data display or maybe suggest from master here? or someone had built 1 of 4x20 LCD became 2 of 2x20LCDs for 2 Microcontrollers. Thank's JBJ |
