Library for programming Pokitto hardware

How to Use

  1. Import this library to online compiler (see button "import" on the right hand side
  2. DO NOT import mbed-src anymore, a better version is now included inside PokittoLib
  3. Change My_settings.h according to your project
  4. Start coding!

Pokitto 5:ea7377f3d1af 53 /** A filesystem for accessing the local mbed Microcontroller USB disk drive
Pokitto 5:ea7377f3d1af 54 *
Pokitto 5:ea7377f3d1af 55 * This allows programs to read and write files on the same disk drive that is used to program the
Pokitto 5:ea7377f3d1af 56 * mbed Microcontroller. Once created, the standard C file access functions are used to open,
Pokitto 5:ea7377f3d1af 57 * read and write files.
Pokitto 5:ea7377f3d1af 58 *
Pokitto 5:ea7377f3d1af 59 * Example:
Pokitto 5:ea7377f3d1af 60 * @code
Pokitto 5:ea7377f3d1af 61 * #include "mbed.h"
Pokitto 5:ea7377f3d1af 62 *
Pokitto 5:ea7377f3d1af 63 * LocalFileSystem local("local"); // Create the local filesystem under the name "local"
Pokitto 5:ea7377f3d1af 64 *
Pokitto 5:ea7377f3d1af 65 * int main() {
Pokitto 5:ea7377f3d1af 66 * FILE *fp = fopen("/local/out.txt", "w"); // Open "out.txt" on the local file system for writing
Pokitto 5:ea7377f3d1af 67 * fprintf(fp, "Hello World!");
Pokitto 5:ea7377f3d1af 68 * fclose(fp);
Pokitto 5:ea7377f3d1af 69 * remove("/local/out.txt"); // Removes the file "out.txt" from the local file system
Pokitto 5:ea7377f3d1af 70 *
Pokitto 5:ea7377f3d1af 71 * DIR *d = opendir("/local"); // Opens the root directory of the local file system
Pokitto 5:ea7377f3d1af 72 * struct dirent *p;
Pokitto 5:ea7377f3d1af 73 * while((p = readdir(d)) != NULL) { // Print the names of the files in the local file system
Pokitto 5:ea7377f3d1af 74 * printf("%s\n", p->d_name); // to stdout.
Pokitto 5:ea7377f3d1af 75 * }
Pokitto 5:ea7377f3d1af 76 * closedir(d);
Pokitto 5:ea7377f3d1af 77 * }
Pokitto 5:ea7377f3d1af 78 * @endcode
Pokitto 5:ea7377f3d1af 79 *
Pokitto 5:ea7377f3d1af 80 * @note
Pokitto 5:ea7377f3d1af 81 * If the microcontroller program makes an access to the local drive, it will be marked as "removed"
Pokitto 5:ea7377f3d1af 82 * on the Host computer. This means it is no longer accessible from the Host Computer.
Pokitto 5:ea7377f3d1af 83 *
Pokitto 5:ea7377f3d1af 84 * The drive will only re-appear when the microcontroller program exists. Note that if the program does
Pokitto 5:ea7377f3d1af 85 * not exit, you will need to hold down reset on the mbed Microcontroller to be able to see the drive again!
