Other Parts Discussed in Thread: CONTROLSUITE
Thread 中讨论的其他器件：controlSUITE
我的代码用于 main()，如下所示：
#include "F28x_Project.h" // Device Header File and Examples Include File
#include "sgen.h"
#define SIGNAL_LENGTH 512
/* Create an instance of Signal generator module */
SGENT_1 sgen = SGENT_1_DEFAULTS;
#pragma DATA_SECTION(v, "SGENipcb");
int v[SIGNAL_LENGTH];
int xn,yn,i;
// external function prototypes
extern void InitSysCtrl(void);
extern void InitPieCtrl(void);
extern void InitPieVectTable(void);
// Prototype statements for functions found within this file.
void Gpio_select(void);
void Setup_ePWM1(void);
void Setup_ePWM2(void);
interrupt void ePWM_compare_isr(void);
void main(void)
{
InitSysCtrl(); // Basic Core Init from SysCtrl.c
EALLOW;
//SysCtrlRegs.WDCR= 0x00AF; // Re-enable the watchdog
EDIS; // 0x00AF to NOT disable the Watchdog, Prescaler = 64
DINT; // Disable all interrupts
Gpio_select(); // setting for ePWM Outputs
Setup_ePWM1(); // init of ePWM1A and ePWM1B
Setup_ePWM2(); // init of ePWM2A and ePWM2B
InitPieCtrl(); // basic setup of PIE table; from PieCtrl.c
InitPieVectTable(); // default ISR's in PIE ; from PieVect.c
EALLOW;
PieVectTable.32 = &ePWM_compare_isr;
EDIS;
//ENABLING ADC INERRUPT
PieCtrlRegs.PIEIER1.bit.INTx6 = 1;
IER |=1; // enable INT1 FOR ADC
EINT;
ERTM;
// Sync ePWM
EALLOW;
CpuSysRegs.PCLKCR0.bit.TBCLKSYNC = 1;
EDIS;
// Start ePWM
EPwm2Regs.TBCTL.bit.CTRMODE = 0; // Un-freeze and enter up-count mode
//while(1)
//{
//}
}
在构建时、此行中出现唯一错误#66预期为"；"：
第48行：PieVectTable.32 =&ePWM_COMPARE_ISR；
中断 void ePWM_COMPARE_ISR (void)中的内容如下：
sgen.offset=1;
sgen.gain=0x7fff; // gain=1
sgen.freq=5369; // freq = 50Hz
sgen.step_max=1000; /* Max Freq= (step_max * sampling freq)/65536 */
sgen.alpha=8192; /* phase_norm =(pi/4/(2*pi))*2^16=8192 */
for(i=0;i<SIGNAL_LENGTH;i++)
{
v[i]=0;
}
for(i=0;i<SIGNAL_LENGTH;i++)
{
sgen.calc(&sgen);
xn=sgen.out;
v[i]=xn;
EPwm1Regs.CMPA.bit.CMPA = v[i] ;
EPwm2Regs.CMPA.bit.CMPA = v[i] ;
}
// Return from interrupt
AdcaRegs.ADCINTFLGCLR.bit.ADCINT1 = 1; // Clear ADC INT1 flag
// Acknowledge this interrupt to receive more interrupts from group 3
PieCtrlRegs.PIEACK.all = PIEACK_GROUP1; // Acknowledge interrupt to PIE
}此函数在 main 之外执行。 我已经在这个论坛上搜索了这个解决方案、但我找不到我的问题的解决方案
此程序的控制台窗口如下所示：
