STM32F429 实测基本数据类型占用空间

实测代码

void CalculateDataTypeSize(void)
{
    printf("sizeof(char}      = %u\r\n", sizeof(char));
    printf("sizeof(short}     = %u\r\n", sizeof(short));
    printf("sizeof(int}       = %u\r\n", sizeof(int));
    printf("sizeof(long}      = %u\r\n", sizeof(long));
    printf("sizeof(long long} = %u\r\n", sizeof(long long));
    printf("sizeof(float}     = %u\r\n", sizeof(float));
    printf("sizeof(double}    = %u\r\n", sizeof(double));
}
