Asjad New Member May 23, 2004 #1 Dear All, Can anyone tell me if it is possible to have the serial comms working on a PIC16F874 with a 2.4576Mhz crystal?? roughly how fast would it be?? Kind regards!

Exo Active Member May 23, 2004 #2 The speed depends on the baudrate generator value (BRG) you program into it... The formula's to calculate are: for high speed Baudrate = OSC / (16 (BRG + 1)) for low speed Baudrate = OSC / (64 (BRG + 1))
