i tried to send data, through serial data communication, from one Microcontroller[Atmel 8052 - AT89c52] to another Microcontroller[Atmel 8052 - AT89c52] and back to the source Microcontroller and then display the data on a LCD[16x2]. both the Microcontrollers have 12Mhz crystal and the baud rate is 2,400, and i have calculated the reload value for TH1 in mode 2[auto-reload mode] as, 256-[12E6/(32 x 12 x 2400)]=242.98, which is rounded off to the nearest integer 243. By doing this i am not getting the expected result. the output on the LCD is some junk value[looks v.weird]. what could b the problem???
hai, thanks Mark. And the h/w connection is properly made, i.e, the Tx and Rx of the 1st Microcontroller are connected to the Rx and Tx pin, respectively, of the 2nd Microcontroler.
