Understanding the Function of Different Pins of an SD Card The graphical symbol for the speed class has a number beside the ‘A’ (A1 and A2).Writing Speed 6MB/s to 90MB/s and Number denote the speed.The graphical symbol for the speed class has a number beside the ‘V’ (V6, V10, V30, V60 & V90.Writing Speed 10MB/s & 30MB/s and Number denote the speed multiply with 10.The graphical symbol for the speed class has a number inside in the ‘U’ (U1 & U3).Writing Speed 2MB/s to 10MB/s and Number Encircled denote the speed.The graphical symbol for the speed class has a number encircled with 'C' (C2, C4, C6, & C10).SD cards are also classified by their “Writing Speed” and “Physical Size” It can be used as an interface for input or output devices as per capacity and Bus speed. SDIO is a type of Secure Digital card interface. It also has a default bus speed of 12.5MB/s to 25MB/s but depending upon the bus type, it can supports up to 3938MB/s (UHS-I, UHS-II, UHS-III, SD-Express). This card has a maximum capacity of 128TB and it can only support the exFAT Filesystem. Next, on the line, we have our most recently upgraded card or the SDUC card, which stands for Secure Digital Ultra-Capacity. The default bus speed of this card is 12.5MB/s to 25MB/s but it supports up to 3938MB/s depend on Bus interfaces (UHS-I, UHS-II, UHS-III, SD-Express) Next, we have our SDXC card or Secure Digital eXtended-Capacity, this card comes with a max capacity of 2TB and it can support both FAT32 and exFAT Filesystem. In a general scenario, this card is supported by a bus speed of 12.5MB/s to 25MB/s, but it supports up to 3938MB/s depending on Bus interfaces (UHS-I, UHS-II, UHS-III, SD-Express). This card has a maximum capacity of 32GB and supports an upgraded FAT32 Filesystem. Next, on the list is another most common card known as the SDHC or Secure Digital High-Capacity card. Other than that, this type of card has a maximum transfer capacity of 12.5MB/s. It stands for Secure Digital Standard Capacity this type of card has a maximum capacity of 2GB and it uses FAT16 Filesystem. The most basic and common card you can find in the market is the SDSC card. Secure Digital card can be subdivided into four categories, a list of which is shown below. Secure Digital cards or SD cards is a non-volatile memory card format developed by the SD Associations (SDA) for use in portable devices. Understanding Different Types of SD Card? You can check those out if you are interested in learning more about PIC. PIC Microcontroller Based Heart Beat Monitor.IoT Based Web Controlled Home Automation.We have also built many other projects with PIC Microcontroller like: So, in this article, we are going to show you how you can simply interface an SD card module with PIC microcontroller and store data inside it. But doing this with a PIC microcontroller is much more difficult than doing it with an Arduino. In one of our previous articles, we have shown an Arduino Based Data Logger, which we used to store temperature and humidity data. This is one example, you can do a lot more with an SD card. this makes the logging capabilities much simpler. Since the price of an SD card is far better than any other storage option, it can be used to store and log data for days. But did you know that you can read and write information on an SD card with the help of a simple 8-bit microcontroller? You heard that right, it's possible to do so, this opens up a bag full of opportunities in embedded systems and design. * * Created by * * This example code is in the public domain * * Tutorial page: */ # include # define PIN_SPI_CS 4 File myFile int myInt = -52 float myFloat = -12.7 String myString = "HELLO" char m圜harArray = "ArduinoGetStarted.A Secure Digital (SD) card is used to store information in many electronic devices, especially smartphone and digital cameras.
