External Storage refers to memory other than CPU cache and memory. Hard disks, optical disks, and USB flash disks can all be called external storage. All the data also exists here, so the allocation method becomes extremely important, which directly affects the computer's running speed.

Note In the division operation:If the two digits of the division are integers, then the result is an integer, the fractional part is omitted, such as 8/3 = 2, and two is a decimal , and The result is a decimal number, such as: 9.0/2 = 4.500000.Take note of the remainder operation:This operation is only suitable for two integers , such as: 10%3 = 1, while 10.0%3 is wrong; The post-op symbol depends on the sy

Recently made a small app about the album, need to read the storage device of the Android phone, first need to obtain the system read and write permission, in the online a good find, for the veteran, may be easy, for the rookie, it is a little difficult, in order to learn, especially write some of their own experience to write down, for reference. If there is any improper, please correct me.Let's start with an introduction to the phone's internal

fixed external space through the lock ale, when the intermediate address (address8 ~ Address15) after the arrival of ale will not be locked, three byte addresses are merged into the total address. If the EAM bit of the mxcon register is not 1, it works the same way as 80C51.There are two special P2 port multiplexing methods for addressing external spaces (EAM = 1, mxcon). movx @ RI and movx @ dptr commands

Use External Storage Each Android-compatible device supports a shared external storage used to save files. This memory can be a removable storage medium (such as an SD card) or internal (non-removable) storage. Files stored in
