Cool Components Workshop Board

The workshop breakout board is a simple, compact board for experimenting with the Mbed. It offers a micro SD card slot, USB A, USB B, and ethernet port (with magnetics). In addition, each mbed pin can be connected to via a solderless header.

Orientation : A simple thing, but lots of people get it wrong. The mbed should be inserted into the board socket so that its USB mini B connector is directly over the mini SD slot.

SD Card Test Code : (This code or probably the library it uses does not work with 100% of SD cards)

#include "mbed.h"
#include "SDFileSystem.h"
 
SDFileSystem sd(p5, p6, p7, p8, "sd"); // mosi, miso, sclk, cs, name
 
DigitalOut myled1(LED1);
DigitalOut myled3(LED3);
 
int main() {
    printf("Hello World!\n");  
    myled3=1;
 
    FILE *fp = fopen("/sd/sdtest.txt", "w");
    if(fp == NULL) {
        error("Could not open file for write\n");
        myled1=1;
        myled3=0;
    }
    fprintf(fp, "If you're reading this text in a file, your SD card has been written to...");
    fclose(fp);
}
