大家好
我使用 AdcoffsetSelfCal 函数、但代码 在 AdcConversion 函数中(AdcRegs.ADCINTFLG.bit.ADCINT1 = 0)停止在线路上。
这是怎么了?
Uint16 AdcConversion(void) { Uint16 index, SampleSize, Mean, ACQPS_Value; Uint32 Sum; index = 0; //initialize index to 0 SampleSize = 256; //set sample size to 256 (**NOTE: Sample size must be multiples of 2^x where is an integer >= 4) Sum = 0; //set sum to 0 Mean = 999; //initialize mean to known value //Set the ADC sample window to the desired value (Sample window = ACQPS + 1) ACQPS_Value = 8; AdcRegs.ADCSOC0CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC1CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC2CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC3CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC4CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC5CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC6CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC7CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC8CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC9CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC10CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC11CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC12CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC13CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC14CTL.bit.ACQPS = ACQPS_Value; AdcRegs.ADCSOC15CTL.bit.ACQPS = ACQPS_Value; //Enable ping-pong sampling // Enabled ADCINT1 and ADCINT2 AdcRegs.INTSEL1N2.bit.INT1E = 1; AdcRegs.INTSEL1N2.bit.INT2E = 1; // Disable continuous sampling for ADCINT1 and ADCINT2 AdcRegs.INTSEL1N2.bit.INT1CONT = 0; AdcRegs.INTSEL1N2.bit.INT2CONT = 0; AdcRegs.ADCCTL1.bit.INTPULSEPOS = 1; //ADCINTs trigger at end of conversion // Setup ADCINT1 and ADCINT2 trigger source AdcRegs.INTSEL1N2.bit.INT1SEL = 6; //EOC6 triggers ADCINT1 AdcRegs.INTSEL1N2.bit.INT2SEL = 14; //EOC14 triggers ADCINT2 // Setup each SOC's ADCINT trigger source AdcRegs.ADCINTSOCSEL1.bit.SOC0 = 2; //ADCINT2 starts SOC0-7 AdcRegs.ADCINTSOCSEL1.bit.SOC1 = 2; AdcRegs.ADCINTSOCSEL1.bit.SOC2 = 2; AdcRegs.ADCINTSOCSEL1.bit.SOC3 = 2; AdcRegs.ADCINTSOCSEL1.bit.SOC4 = 2; AdcRegs.ADCINTSOCSEL1.bit.SOC5 = 2; AdcRegs.ADCINTSOCSEL1.bit.SOC6 = 2; AdcRegs.ADCINTSOCSEL1.bit.SOC7 = 2; AdcRegs.ADCINTSOCSEL2.bit.SOC8 = 1; //ADCINT1 starts SOC8-15 AdcRegs.ADCINTSOCSEL2.bit.SOC9 = 1; AdcRegs.ADCINTSOCSEL2.bit.SOC10 = 1; AdcRegs.ADCINTSOCSEL2.bit.SOC11 = 1; AdcRegs.ADCINTSOCSEL2.bit.SOC12 = 1; AdcRegs.ADCINTSOCSEL2.bit.SOC13 = 1; AdcRegs.ADCINTSOCSEL2.bit.SOC14 = 1; AdcRegs.ADCINTSOCSEL2.bit.SOC15 = 1; // DELAY_US(ADC_usDELAY); // Delay before converting ADC channels int i; for ( i= 0 ; i<10000; i++); //ADC Conversion AdcRegs.ADCSOCFRC1.all = 0x00FF; // Force Start SOC0-7 to begin ping-pong sampling while( index < SampleSize ){ //Wait for ADCINT1 to trigger, then add ADCRESULT0-7 registers to sum while (AdcRegs.ADCINTFLG.bit.ADCINT1 == 0){} AdcRegs.ADCINTFLGCLR.bit.ADCINT1 = 1; //Must clear ADCINT1 flag since INT1CONT = 0 Sum += AdcResult.ADCRESULT0; Sum += AdcResult.ADCRESULT1; Sum += AdcResult.ADCRESULT2; Sum += AdcResult.ADCRESULT3; Sum += AdcResult.ADCRESULT4; Sum += AdcResult.ADCRESULT5; Sum += AdcResult.ADCRESULT6; // Wait for SOC9 conversion to start, which gives time for SOC7 conversion result while( AdcRegs.ADCSOCFLG1.bit.SOC9 == 1 ){} Sum += AdcResult.ADCRESULT7; //Wait for ADCINT2 to trigger, then add ADCRESULT8-15 registers to sum while (AdcRegs.ADCINTFLG.bit.ADCINT2 == 0){} AdcRegs.ADCINTFLGCLR.bit.ADCINT2 = 1; //Must clear ADCINT2 flag since INT2CONT = 0 Sum += AdcResult.ADCRESULT8; Sum += AdcResult.ADCRESULT9; Sum += AdcResult.ADCRESULT10; Sum += AdcResult.ADCRESULT11; Sum += AdcResult.ADCRESULT12; Sum += AdcResult.ADCRESULT13; Sum += AdcResult.ADCRESULT14; // Wait for SOC1 conversion to start, which gives time for SOC15 conversion result while( AdcRegs.ADCSOCFLG1.bit.SOC1 == 1 ){} Sum += AdcResult.ADCRESULT15; index+=16; } // end data collection //Disable ADCINT1 and ADCINT2 to STOP the ping-pong sampling AdcRegs.INTSEL1N2.bit.INT1E = 0; AdcRegs.INTSEL1N2.bit.INT2E = 0; while(AdcRegs.ADCSOCFLG1.all != 0){} // Wait for any pending SOCs to complete // Clear any pending interrupts AdcRegs.ADCINTFLGCLR.bit.ADCINT1 = 1; AdcRegs.ADCINTFLGCLR.bit.ADCINT2 = 1; AdcRegs.ADCINTOVFCLR.bit.ADCINT1 = 1; AdcRegs.ADCINTOVFCLR.bit.ADCINT2 = 1; //reset RR pointer to 32, so that next SOC is SOC0 AdcRegs.SOCPRICTL.bit.SOCPRIORITY = 1; while( AdcRegs.SOCPRICTL.bit.SOCPRIORITY != 1 ); AdcRegs.SOCPRICTL.bit.SOCPRIORITY = 0; while( AdcRegs.SOCPRICTL.bit.SOCPRIORITY != 0 ); Mean = Sum / SampleSize; //Calculate average ADC sample value return Mean; //return the average }//end AdcConversion
您好!
您能否尝试从 C2000WARE 导入此示例、并查看您是否有同样的问题?
此示例位于[Your_C2000Ware]\device_support\f2803x\examples\c28\

感谢您的回答、但 这没有解决 我的问题。
当我使用 DELAY_US 宏时,我的代码项非法 ISR , 当我更改延迟代码(使用 for loop)时,代码 在行 (AdcRegs.ADCINTFLG.bit.ADCINTT1 ==0)停止。
您好!
您是否从闪存运行程序? 我注意到了示例中的这条注释。

我使用 F28035连接器

您好!
好的、看起来您的程序从闪存运行、因此您的问题可能是由于需要将 ramfuncs 从闪存复制到 RAM 所致。
在尝试运行我之前提到的示例时、您是否看到过同样的错误?
