sending data wireless ccs compiler

hi,
i hv been wrking with dot matrix.i want to send the string(to display) from pc to the ucontroller.hw can i send the string to the ucontroller ?serial communication?if so,hw to accomplish it?plz ,inform me in details.


with regards..

Yes you can easily send te data to Microcontroller from Pc through the Serial communication port. In 8051 the data from the Serial cable to SBUFF. which is the register.

SFR (Special Function Register)

So serial communication is easily done through a DB9 Cable.

Good Luck

for interfacing 8051 to PC you will require MAX 232 IC. Its very easily available
here is a working code for using 8051's UART

and you can use Hyper Terminal for sending data from PC to the controller

Thanks fr the post
what about sending data wireless to the PIC?

 

[amol_shah]

simplest and cheapest method will be using TV remote as transmitter (that saves you time and cost in designing the transmitter)
use a philips remote control which has RC5 protocol as o/p : https://www.dnatechindia.com/index.php/Tutorials/8051-Tutorial/RC5-Protocol.html
use TSOP 1738 for receiver
other methods RF, GSM, bluetooth

i`ll prefer u to use PIC and CCS C Compiler...very easy to use specially for newbie...

I think you better use PIC and send your Character via COM Port USART Module of PIC will receive it.
then you can display your character using your own library functions.

Please guide the circuit diagram for PIC!
Thanks!!

I suggest you to do it with a wireless cable replacement module. I use BLUEMORE series from Eikon www.eikonsite.it

Once setted, by AT command or a freeware on PC, it works like a transparent UART for your microcontroller

TTL levels or 3,3V or RS232!
