hi everybody,
i am implementing my project using RF modules and i need to transmit data through the Txd serial pin of the 8051 microcontroller. i am transmitting at a baud rate of 1200, which is -12 in programming with 11.0592Mhz crystal.
i just wanted to find out what values of capacitors i should connect to the 8051 crystal oscillator pin in the 8051 connection or the formula for how to get the capacitor values and whether it should be polarized or not. i currently connected 30pf but it is not transmitting.
please help needed here.
