F28379d complete project example

Thank you for your response.  I finally was able to import it using the resource explorer. I have another issue. I am trying to use that project but replace the main code to what I have for my own purpose. Here is my code that I'm trying to replace with the code in "dual_axis_servo_drive.c"

#include "F2837xd_Device.h"
#include "IQmathLib.h"
#include "math.h"
extern void InitSysCtrl(void);
extern void InitPieVectTable(void);
extern void InitPieCtrl(void);
interrupt void ePWM1_compare_isr(void);
//#pragma DATA_SECTION(sine_table,"IQmathTables");
//_iq30 sine_table[999];
#define PI 3.14159
static float Freq = 1;
static float MI = 0.1;
static float Angle = 0;

}

When I copy this code I get the following errors:

Could you please help me with this?

Hi Ahmad,

From the screenshot, the problem is build error #10234-D. Could you take a look at this post which is purposed to resolve this issue?
