hello...i want to send text which contains a series of strings into the 89c51 through rs232 from pc.can anyone please suggest the code in embedded c... i need to mention u that the text is from a text document generated by a speech to text converter software...please help me out in this....

store the string in an array and send it to controller till you get some character (which indicates end of text)...

its normal serial comm program, nothing more than that..

but i have said that the text is from a word document generated by a speech to text converter software....is there any need to read the file using a c program and then send the data???

speech to text is an external device i feel.......... so the text you get has to be given to controller in some way... you can also send text file through serial communication. this file has to be stored in a array big enough to store the complete text file to be used by controller......

In cases where we use HM2007 for voice recognition the speech is converted to text and is given out as 8 bit data that is connected to controller 8 port pins....

if it is from pc then that data has to be read by the controller.....

do a simple exercise.. create a text file and keep some 20 characters in it ansd save it as " .txt". (give some file name)

connect controller to PC and through hyperterminal, select transfer tab... and select send text file. select the text file and send it....

in controller receive the file in a array and read it and display it on LCD... try this and let me know..
