标题: 串口助手是不是不能显示浮点型数据
串口助手上只能显示整型数据么浮点型就变成很长的一串数据 [attach]44821[/attach]
这是串口助手的问题还是程序的问题 g_fCarSpeed=(g_nLeftCount + g_nRightCount) / 2; f是浮点型 n是整形
printf("\n接收到 %d 个脉冲", g_fCarSpeed);

吧浮点型转化成字符串就可以显示了，不然只能16进制显示

我记得飞思卡尔的库里有printf的函数直接把浮点转换成带符号和小数点的字符串。可以在串口助手中直接显示小数。

怎么弄呀，同求

%d 加整数，改成%f 就能加浮点了
