杰发科技AC7840——打印所有GPIO的PORT配置寄存器

代码如下

    unsigned int reg = 0;
    for (unsigned int j = 0; j < 5; j++)
    {
        unsigned char count = 0;
        unsigned int address = 0x40085200;
        address += j * 0x100;
        for (unsigned int i = 0; i < 32; i++)
        {

            reg = READ_MEM32(address + i * 4); 
            printf("P%c%02d：0x%x    ", 65 + j, i, reg);
            count++;
            if (count == 5)
            {
                printf("\r\n");
                count = 0;
            }
        }
        printf("\r\n\r\n");
    }

结果如下所示
