#The 7th Lichuang Electronic Competition#EMCP to TF card

Micro SD Card, formerly known as Trans-flash Card (TF card), was officially renamed Micro SD Card in 2004. It was invented by SanDisk and is mainly used in mobile phones.
Before Micro SD came on the market, mobile phone manufacturers used embedded memory. Although this type of module is easy to install, it has the problem of not being able to meet the actual trend demand - the capacity is limited and there is no room for upgrade. Micro SD imitates the application mode of SIM card, that is, the same card can be used in different models of mobile phones, so that mobile phone manufacturers do not have to worry about the research and development of plug-in card design. Micro SD card can be called a removable storage IC.
Micro SD card is a very small flash memory card. Its format originated from SanDisk. Originally, this memory card was called T-Flash, and later renamed Trans Flash; and the reason for renaming it Micro SD is that it was adopted by the SD Association (SDA). Other memory cards adopted by SDA include Mini SD and SD cards. It is mainly used in mobile phones, but due to its small size and increasing storage capacity, it has been used in GPS devices, portable music players and some flash memory disks. Its size is 15mmx11mmx1mm, which is almost the size of a fingernail. It is the smallest memory card currently. It can also be connected to the SD card slot through an SD adapter card. Currently, Micro SD cards provide 128MB, 256MB, 512MB, 1G, 2G, 4G, 8G, 16G, 32G, 64G, and 128G capacities (During the MWC 2014 World Mobile Communications Conference, SanDisk broke the tradition of the maximum capacity of 64GB for storage cards and officially released a Micro SD XC storage card with a capacity of up to 128GB.

 
*2. Project attributes
EMCP to TF card
 
Note: Please indicate whether the project is publicly disclosed for the first time; whether the project is original; whether the project has won awards in other competitions, if so, please describe the details of the award; whether the project has participated in the defense at school.
 
* 3. Open source agreement
Please enter the content...
EMCP
Note: Altruism is self-interest, please read the following carefully.
Embrace open source and give the project unlimited value. It is recommended that more than 80% of the core functions of the project be open source;
if a part of the function is irreplaceable and the project cannot solve the corresponding problem after deleting it, then the function implemented by this part is the core function of the project; for example, an electronic load is designed and a host computer software is designed to monitor power changes, then the electronic load is the core function, and the host computer software is an auxiliary function; for example, an isolated 485 module is used in the electronic load to communicate with the host computer, then the communication function implemented by this 485 module is an auxiliary function;
the project should choose an open source protocol that suits it. If the project quotes other open source projects, the source should be indicated and the original author’s open source protocol regulations should be followed; original projects are recommended to use the GPL3.0 open source protocol;
functions implemented by directly quoting the original circuit or original code of the open source project cannot be used as the core functions of your own project, and functions directly implemented using general modules on the market cannot be used as the core functions of your own project.
