Hi, Does anyone have any sample code that shows how to set up uart 0 to use the internal Baud rate generator ?
Dear Andy, I am also facing the same problem with 89C669. Do you have any solution for this? Please help me. Thanks in advance. Suhas
My Code for Using Built in baud generator for both serial ports. Hope it helps :- // initialise on board comms BRGCON = 0; //12 MHz BRGR0 = 0xD2; BRGR1 = 0x4; //Set To Baud rate generator to 9600 //11.0592 MHz // BRGR0 = 0x7E; // BRGR1 = 0x4; //Set To Baud rate generator to 9600 BRGCON = 3; T2CON = 0x30; // RCLK=1. TCLK = 1, Timer 2 Disabled SCON = 0x50; // SCON: mode 1, 8-bit UART, enable rcvr REN_0 = 1; ES0 = 1; // Enable Interrupt TI_0 = 1; // TI: set TI to send first char of UART //Uart 2 S1CON = 0x50; // SCON: mode 1, 8-bit UART, enable rcvr REN_1 = 1; ES1 = 1; TI_1 = 1; // TI: set TI to send first char of UART
