Hi all,,,
I just wanted to inquire about the serial communication in Atmel 89c51,
In fact I wrote a simple program to communicate with a GPS module, and then display the data on a LCD, the longitude is…., the latitude is…, the altitude is …., blah blah blah,
The weird action is I forgot to connect the MC with the module, and guess what ?!!
I found the LCD display the longitude is …….., the latitude is ….., the altitude is …., blah blah blah ,
So? How that happened? I think the MC couldn't pass the serial communication part if it didn't get any data at the Rx pin,
Am I right or what?!!
Please somebody help me !
