Please help me in setting the baud rate in 89c51.I am doing project in 8051 which is a message transmitter.What i mean is there are two blocks in my project one is transmitter And other is receiver.
The transmitter consist of 64 keys which is obtained by 8*8 matrix key board.I am aiming for A to Z alphabets & 0 to 9 no.
After decoding which key is pressed i has to transmit the pressed key which will display on the receiver.I am planing to use 433Mhz transmitter & receiver the problem is that the transmitter and receiver has only 20kbps speed so i has to reduce the baud rate considerably.
