DLOG_4ch.asm不更新数据

Step 1 Add library header file in the file {ProjectName}-Main.c

#include “DPLib.h”

Step 2 Declare the terminal pointers in C in the file {ProjectName}-Main.c

// —————————- DPLIB Net Pointers ———————

// Declare net pointers that are used to connect the DP Lib Macros here

// and the data variables being used by the macros internally

//DLOG_4ch – instance #1

extern volatile long *DLOG_4ch_i1Ptr;

extern volatile long *DLOG_4ch_i2Ptr;

extern volatile long *DLOG_4ch_i3Ptr;

extern volatile long *DLOG_4ch_i4Ptr;

extern volatile int16 *DLOG_4ch_buff1Ptr;

extern volatile int16 *DLOG_4ch_buff2Ptr;

extern volatile int16 *DLOG_4ch_buff3Ptr;

extern volatile int16 *DLOG_4ch_buff4Ptr;

extern volatile long DLOG_4ch_TrigVal;

extern volatile int16 DLOG_4ch_PreScalar;

extern volatile int16 DLOG_4ch_Size;

Step 3 Declare signal net nodes/ variables in C in the file {ProjectName}-Main.cc Note that the DLOG_SIZE is a #define in the {ProjectName}-Settings.h and can be modified if needed. Note these signal nets name may change from system to system, there is no dependency on the signal net names to the

Step 4 “Call” the DPL_CLAInit() to initialize the macros and “connect” the module terminals to the signal nets in “C” in {ProjectName}-Main.c

Step 5 Add the ISR assembly file “{ProjectName}-DPL-ISR.asm” to the project

Step 6 Include the macro’s assembly file in the {ProjectName}-DPL-ISR.asm

Step 7 Instantiate the INIT macro in assembly (this is one-time pass through code) inside the C-callable DPL_Init() function which is defined in{ProjectName}-DPL-ISR.asm

;Macro Specific Initialization Functions

DLOG_4ch_INIT 1 ; DLOG_4CH Initialization

Step 8 Call the run time macro in assembly inside the C-callable function DPL_ISR() which is the looped or ISR code. The function is defined in{ProjectName}-DPL-ISR.asm ;

”Call” the Run macro

DLOG_4ch 1 ; Run the DLOG_4CH Macro

Step 9 Include the memory sections in the {DeviceName}-{RAM/FLASH}- {ProjectName}.CMD. Note that the net pointers and the internal data are forced to be placed in a single data page by use of the .usect directive in the source file of the module.

/*DLOG_4ch sections*/ DLOG_4ch_Section : > dataRAM PAGE = 1

为什么DBUFF1，DBUFF2，DBUFF3，DBUFF4不更新值了，需要怎么调试

Susan Yang：

请问能否给出您的相关代码呢？

一般都是

// Initialize DATALOG moduledlog.iptr1 = &DlogCh1;dlog.iptr2 = &DlogCh2;dlog.iptr3 = &DlogCh3;dlog.iptr4 = &DlogCh4;dlog.trig_value = 0x1;dlog.size = 0x0C8;dlog.prescalar = 5;dlog.init(&dlog);然后在main_ISR（）中调用类似下面的代码

/ ------------------------------------------------------------------------------
//Connect inputs of the DATALOG module// ------------------------------------------------------------------------------DlogCh1 = (int16)_IQtoIQ15(svgen1.Ta);DlogCh2 = (int16)_IQtoIQ15(svgen1.Tb);DlogCh3 = (int16)_IQtoIQ15(svgen1.Tc);DlogCh4 = (int16)_IQtoIQ15(svgen1.Tb-svgen1.Tc);

/ ——————————————————————————
//    Connect inputs of the DATALOG module
// ——————————————————————————
    DlogCh1 = (int16)_IQtoIQ15(svgen1.Ta);
    DlogCh2 = (int16)_IQtoIQ15(svgen1.Tb);
    DlogCh3 = (int16)_IQtoIQ15(svgen1.Tc);
    DlogCh4 = (int16)_IQtoIQ15(svgen1.Tb-svgen1.Tc);
