Splet06. mar. 2024 · 0xf0在单片机中表示十六进制的f0,换算为十进制为240,二进制为11110000,所以一个变量或0xf0后,结果的高4位一定为1,低4位根据变量的第四位的值来判断: 所以DSG1＝Num%10 0xf0最后的结果为0xfX,其中X为Num的个位. 感觉说的有点乱,有不懂的再问吧~~. 发布于 2024-03-06 00:02. 赞同 3. Splet06. maj 2024 · PORTC = (PORTC & 0xf0) ( (row >> 6) & 0x0f); Let’s say, for example: PORTC is B10111011 and that row is B11010011. (PORTC & 0xf0) is B10111011 & B11110000. Which reduces to B10110000. In other words, the 4 lower order bits of PORTC are masked out. (row >> 6) is B11010011 shifted right 6 places, that is B00000011.

Splet20. sep. 2012 · 0x0f = 00001111. So a bitwise & operation of 0x0f with any other bit pattern will retain only the rightmost 4 bits, clearing the left 4 bits. If the input has a value of 01010001, after doing &0x0F, we'll get 00000001 - which is a pattern we get after clearing the left 4 bits.
