xWhitfordx 0:77006df50c28 5 * A test program for the MCP4725 DAC Library. This Test Application requires the following:
xWhitfordx 0:77006df50c28 6 * * An MCP4725 connected to the I2C bus of the mbed LPC1768.
xWhitfordx 0:77006df50c28 7 * * The analog out of the MCP1768 connected to Pin15 (analog in) of the mbed LPC1768.
xWhitfordx 0:77006df50c28 8 *
xWhitfordx 0:77006df50c28 9 *
xWhitfordx 0:77006df50c28 10 * This is a stripped down version of the MCP4725_Library_Test found online, and should make the necessary commands more clear.
