写一个bin转hex文件的c代码

以下是一个简单的bin转hex文件的c代码，可以将指定的二进制文件转换为对应的Intel HEX格式的文本文件：

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[]) {
    FILE *fp_in, *fp_out;
    int ch, byte_count, addr_hi, addr_lo, record_type, sum, i;
    unsigned char data[16];
    long int address = 0;

    if (argc != 3) {
        printf("Usage: bin2hex input_file output_file\n");
        exit(1);
    }

    if ((fp_in = fopen(argv[1], "rb")) == NULL) {
        printf("Error: can't open input file %s.\n", argv[1]);
        exit(1);
    }

    if ((fp_out = fopen(argv[2], "w")) == NULL) {
        printf("Error: can't create output file %s.\n", argv[2]);
        exit(1);
    }

    while ((ch = fgetc(fp_in)) != EOF) {
        byte_count = 1;
        addr_hi = (address >> 8) & 0xFF;
        addr_lo = address & 0xFF;
        record_type = 0;
        data[0] = ch;

        while ((ch = fgetc(fp_in)) != EOF && byte_count < 16) {
            data[byte_count] = ch;
            byte_count++;
        }

        sum = byte_count + addr_hi + addr_lo + record_type + data[0];

        fprintf(fp_out, ":%02X%02X%02X%02X", byte_count, addr_hi, addr_lo, record_type);

        for (i = 0; i < byte_count; i++) {
            fprintf(fp_out, "%02X", data[i]);
            sum += data[i];
        }

        fprintf(fp_out, "%02X\n", (-sum) & 0xFF);
        address += byte_count;
    }

    fprintf(fp_out, ":00000001FF\n");

    fclose(fp_in);
    fclose(fp_out);

    printf("Conversion finished.\n");

    return 0;
}

使用方法：编译并执行可执行文件，将需要转换的二进制文件作为第一个参数传入，将转换后的文本文件保存为第二个参数指定的文件中。例如：```bin2hex input.bin output.hex```
