I tried to use c0851F060's UART0,but I found there is no output signal from tx0 and rx0(I using crossbar to mapping tx0 rx0 to P_0,P_1),I don't know why?,so can anyone remind me that any passable wrong I colud
make?
p.s my internal oscillator is 24.5Mhz,how can I create baud rate 9600? thanks for gave me advice friends,I still confuse,so I repost this problem.My program as below:
#include // SFR declarations
int i; char g=0x35;
void Oscillator_Init() { SFRPAGE = CONFIG_PAGE; OSCICN = 0x82;
}void Timer_Init() { SFRPAGE = TMR2_PAGE; TMR2CN = 0x04; RCAP2L = 0xFD; RCAP2H = 0xFF;
}void UART_Init() { SFRPAGE = UART0_PAGE; SCON0 = 0x50; SSTA0 = 0x05;
}void Port_IO_Init() { // P0.0 - TX0 (UART0), Push-Pull, Digital // P0.1 - RX0 (UART0), Open-Drain, Digital // P0.2 - Unassigned, Open-Drain, Digital // P0.3 - Unassigned, Open-Drain, Digital // P0.4 - Unassigned, Push-Pull, Digital // P0.5 - Unassigned, Push-Pull, Digital // P0.6 - Unassigned, Push-Pull, Digital // P0.7 - Unassigned, Push-Pull, Digital

// P3.0 - Unassigned, Open-Drain, Digital // P3.1 - Unassigned, Open-Drain, Digital // P3.2 - Unassigned, Open-Drain, Digital // P3.3 - Unassigned, Open-Drain, Digital // P3.4 - Unassigned, Open-Drain, Digital // P3.5 - Unassigned, Open-Drain, Digital // P3.6 - Unassigned, Open-Drain, Digital // P3.7 - Unassigned, Open-Drain, Digital
SFRPAGE = CONFIG_PAGE; P0MDOUT = 0xF1; XBR0 = 0x04; XBR2 = 0x40;
}// Initialization function for device, // Call Init_Device() from your main program void Init_Device(void) { Oscillator_Init(); Timer_Init(); UART_Init(); Port_IO_Init();
}void delay(int x) { int i; for(i=0;i
