This video show demonstration of programmed PIC 16F84 microcontroller for testing Hitachi based HD44780 or compatible LCD.
Program uses 74LS138 based keybord with 8 SPST switches and can be easy modified to use more switches (e.g. 32, 64 or so).
These 8 switches are used for actions like printing characters from ASCII table, moving cursor right/left, clearing screen and cursor to home position, shifting display right or left and changing leters form small to upper or going to nubers if you press and hold last taster for 2 sec. Many options can be implemented. Thanks for watching, cheers...
Повторяем попытку...
