AMEBA RTL8722DM
Ameba RTL8722DM is a low-power dual-band WLAN and BLE(Bluetooth Low Energy) SoC by Realtek. The RTL8722DM also include memory for Wi-Fi protocol functions and application making it simple for anyone to develop various kind of IoT applications. At the same time it has a wide range of peripheral interfaces. With all these interfaces, it can connect to most of the electronics components like LEDs, temperature and humidity sensors, and so on.
FATfs
FatFs is a generic FAT/exFAT filesystem module for small embedded systems.
Supplies
Ameba D [RTL8722DM_mini] x1
MicroSD card x1
Programming
Firstly, insert a MicroSD card into the onboard SD card Reader of RTL8722DM_mini board.
Next, to open the example code, go to "File" -> "Examples" -> "AmebaFatfsSDIO"-> "file_read_write".
Final Results
Upload the code and once the upload is finish, press the reset button on the Ameba.
In the example code, we created the text file "test.txt" with content "hello world". Read the file and print content to a serial monitor.
Next, insert the SD card into a card reader and check whether the operations have succeeded.
