HLS错误记录（1）ERROR: [HLS 214-126] Parameter ‘led‘ is a C language arbitrary-precision integer type

官网解决方案：


建议都是用C++语言来进行HLS的开发

将代码换成C++语言风格后，此错误得到解决，

#include <ap_int.h>

#define DELAY 50000000

void led_twinkle(ap_int<2> *led){
    
    

	int i = 0;

	for(i = 0; i < DELAY; i++){
    
    
		if(i < DELAY/2)
			*led = 1;
		else
			*led = 2 ;
	}
}

原在C综合是报错的代码：

#include <ap_cint.h>

#define DELAY 50000000

void led_twinkle(uint2 *led){
    
    
#pragma HLS INTERFACE ap_none port=led
#pragma HLS INTERFACE ap_ctrl_none port=return
	int i = 0;

	for(i = 0; i < DELAY; i++){
    
    
		if(i < DELAY/2)
			*led = 1;
		else
			*led = 2 ;
	}
}
