Electronic notice board by using 8051 controller with keil and proteus

[@mehdikian4600]

i got it all the same copy as your codes, however when the virtual terminal window opens and i try to type , nothing shows either in virtual terminal window or on the LCD screen. looks like the virtual terminal can not read from the keyboard. any idea how to fix this issue? thank you

[@seshanandareddy6078]

Check your hardware connections , you have to connect RXD with TXD, TXD with RXD.

@@seshanandareddy6078 I did the same thing but not able to type

[@BhavanRB]

the same problem if you get the solution please post it

[@abhinavshukla6558]

Can you share the assembly language code for the same

If i implement it on hardware which instruments as a replacement of virtual terminal

Same problem for me too. Were you able to solve it?

Can we write this program using arduino uno and how to simulate?
