i have a program that i have burned into my controller(p89v51rd2)... now it has a vb interface and it receives hex file character by char...
i.e :120000000ab2345
it receives as : ,1,2,0....and so on into a char array[1000]...and when i display it on to the hyperterminal it displays the dat send...
but when i put the power off and try to receive without it shows junk values.... so my data is not stored permanently into my microcontroller... so how do i access storage area of my controller so that i can store some data into it and carry my sytem to somewhere else and then retrieve the data there...
