As long you can receive UART to MCS-51 >and could drive LCD (4 bits or 8 bits) it would be easy. Yes,it was easy but your recomended company sale the serial very expensive.. I'm using simple kit which only 10US$ each. JBJ JBJ , so far I dont know if pre built LCD with UART is there or not . LCDs comes with databus interface ,you need to drive them in 4-bit /8-bit bus mode with your MCU . You also need to connect the TX and RX lines of the MCU to PC or what ever you need to communicate via translator IC . Now the MCU should send command to PC when it needs to display data or the process can be indepandant of this .That is what ever the PC transmits the MCU which is interfaced to the LCD as well displays it. Darek Rogowski already said a lot , see the following link for interfacing LCD to processor http://www.mcselec.com/index.php...&Itemid=57 . You may also search for PC and 8051 UART connection and there are 100000000000000 examples on the net one such is here http://www.svet-el.si/english/download/serial.bas. AP |
