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...
Presumably, that's because you are putting it into Volatile memory?
You need to either put it into non-volatile memory, or provide a backup power supply so that your volatile memory doesn't lose its content!
