guys iam new to this area i have started working on this thing since last week i am testing UART program using 89c52 with baudrate 2.4k(0xf4). using 11.592 crystal and sample program is from atmel. nothing is coming out from that txd pin. please help me..
i was checking if there are any voltage transition levels at txd pin... with WHAT? a scope?, a LED?, a voltmeter? a rusty nail?
