hi, i am trying to connect rf module with 8051. i have connected rf module using UART. i have transmitted and received the data but am not able to compare it with stored value at the receiver end. Also there is some voltage drop in the receiver output as soon as i connect the Rx pin to the reciever module. Can anyone help?? thnaks.
None of this has anything to do with Keil!
We are discussing hardware issues here - and that is hard to do without a schematic diagram of the system - aka "circuit diagram"
This forum doesn't support posting images - another reason why this is not a great place for such discussions!
You might be better to go to http://www.8052.com/forum If you do, be sure to give a full & clear description of what you are trying to achieve, what you are using, what you have done so far, and what problems you are having. Give a link to this thread, and also update this thread with a link. Show your schematic. Include links to your datasheets. etc...
