1 F2812测试程序中关于事件管理器定时器的程序示例中函数
void init_eva_timer1(void)
{
// Initialize EVA Timer 1:
// Setup Timer 1 Registers (EV A)
EvaRegs.GPTCONA.all = 0;
// Set the Period for the GP timer 1 to 0x0200;
EvaRegs.T1PR = 0x0200; // Period
EvaRegs.T1CMPR = 0x0000; // Compare Reg
// Enable Period interrupt bits for GP timer 1
// Count up, x128, internal clk, enable compare, use own period
EvaRegs.EVAIMRA.bit.T1PINT = 1;
EvaRegs.EVAIFRA.bit.T1PINT = 1;
// Clear the counter for GP timer 1
EvaRegs.T1CNT = 0x0000;
EvaRegs.T1CON.all = 0x1742;
// Start EVA ADC Conversion on timer 1 Period interrupt
EvaRegs.GPTCONA.bit.T1TOADC = 2;
}
如果我想1秒钟中断一次，那么EvaRegs.T1PR该设为多少？谢谢！ |
