moreover my Tx and Rx pins refers 2V and 5V when i checked with my multimeter is it normal??
The Tx pin is an input pin. You can't measure serial activity using a multimeter.
The Rx pin is an output pin. There is not a lot of output activity during sketch upload. The Rx is high until there is activity, so measuring 5V is normal.
The upload also takes more time
Than what? Baking a loaf of bread?
and it doesnt upload anything.
bro i said the code is not uploading since my GUI shows uploading for more than half nd hr and there s no reaction in the board...TX light is ON...!!
there is no pgm in ma micro-controller and stil when i measured the potential diff in ma 0 nd 1 pin i received 5V
