процессор TMS320F2812. Разница во времени почти в два раза.
вот мой пример:
#if defined (F_BOOT)
#pragma CODE_SECTION(adc_isr, "ramfuncs");
#endif
main()
{
// Setup the peripherial devices:
SystemSetup();
// Wait for ADC interrupt:
while(1)
{
LoopCount++;
if (LoopCount > 500000){
LoopCount = 0;
GpioDataRegs.GPFTOGGLE.all = 0x4000;
}
}
}
void SystemSetup(void){
// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral Clocks
// This example function is found in the DSP281x_SysCtrl.c file.
InitSysCtrl();
// For this example, set HSPCLK to SYSCLKOUT / 6 (25Mhz assuming 150Mhz SYSCLKOUT)
EALLOW;
SysCtrlRegs.HISPCP.all = 0x3; // HSPCLK = SYSCLKOUT/6
EDIS;
// Step 2. Initialize GPIO:
// This example function is found in the DSP281x_Gpio.c file and
// illustrates how to set the GPIO to it's default state.
InitGpio();
// For this example use the following configuration:
Gpio_select();
// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts
DINT;
// Initialize the PIE control registers to their default state.
// The default state is all PIE interrupts disabled and flags
// are cleared.
// This function is found in the DSP281x_PieCtrl.c file.
InitPieCtrl();
// Disable CPU interrupts and clear all CPU interrupt flags:
IER = 0x0000;
IFR = 0x0000;
// Initialize the PIE vector table with pointers to the shell Interrupt
// Service Routines (ISR).
// This will populate the entire table, even if the interrupt
// is not used in this example. This is useful for debug purposes.
// The shell ISR routines are found in DSP281x_DefaultIsr.c.
// This function is found in DSP281x_PieVect.c.
InitPieVectTable();
// Interrupts that are used in this example are re-mapped to
// ISR functions found within this file.
EALLOW; // This is needed to write to EALLOW protected register
PieVectTable.ADCINT = &adc_isr;
EDIS; // This is needed to disable write to EALLOW protected registers
#if defined (F_BOOT)
// Copy time critical code and Flash setup code to RAM
// This includes the following ISR functions: EvaTimer1(), EvaTimer2()
// EvbTimer3 and and InitFlash();
// The RamfuncsLoadStart, RamfuncsLoadEnd, and RamfuncsRunStart
// symbols are created by the linker. Refer to the F2812.cmd file.
MemCopy(&RamfuncsLoadStart, &RamfuncsLoadEnd, &RamfuncsRunStart);
// Call Flash Initialization to setup flash waitstates
// This function must reside in RAM
InitFlash();
#endif
// Step 4. Initialize all the Device Peripherals:
// This function is found in DSP281x_InitPeripherals.c
// InitPeripherals(); // Not required for this example
InitAdc(); // For this example, init the ADC
// Step 5. User specific code, enable interrupts:
// Enable ADCINT in PIE
PieCtrlRegs.PIEIER1.bit.INTx6 = 1;
IER |= M_INT1; // Enable CPU Interrupt 1
EINT; // Enable Global interrupt INTM
ERTM; // Enable Global realtime interrupt DBGM
LoopCount = 0;
ConversionCount = 0;
// Configure ADC
AdcRegs.ADCMAXCONV.all = 0x0001; // Setup 2 conv's on SEQ1
AdcRegs.ADCCHSELSEQ1.bit.CONV00 = 0x3; // Setup ADCINA3 as 1st SEQ1 conv.
AdcRegs.ADCCHSELSEQ1.bit.CONV01 = 0x2; // Setup ADCINA2 as 2nd SEQ1 conv.
AdcRegs.ADCTRL2.bit.EVA_SOC_SEQ1 = 1; // Enable EVASOC to start SEQ1
AdcRegs.ADCTRL2.bit.INT_ENA_SEQ1 = 1; // Enable SEQ1 interrupt (every EOS)
// Configure EVA
// Assumes EVA Clock is already enabled in InitSysCtrl();
EvaRegs.T1CMPR = 0x0080; // Setup T1 compare value
EvaRegs.T1PR = PWM_PERIOD; // Setup period register
EvaRegs.GPTCONA.bit.T1TOADC = 1; // Enable EVASOC in EVA
EvaRegs.T1CON.all = 0x1042; // Enable timer 1 compare (upcount mode)
}
interrupt void adc_isr(void)
{
GpioDataRegs.GPFSET.all = 0x0010;
...
GpioDataRegs.GPFCLEAR.all = 0x0010;
return;
}
прерывание выполняется во время, т.е. времена одинаковые, что под эмультором, что из Flash.
Пробовал изменить Val в InitPll(Val); изменяется общее время,т.е. проблема не решается.
В общем скажите, где копать, пожалуйста.
Заранее благодарен.
