By not connecting all the LPC1768 microcontroller pins to the mbed external pins a number of microcontroller peripherals are ‘lost’ for use. Identify which ones these are, for ADC, UART, CAN, I2C, SPI and DAC. Solution SPI , I2C, UART , CAN ARE SERIAL INTERFACES SO THEY WILL LOST . BUT WHERE ADC AND DAC ARE CONVERTERS , THEY ARE NOT PERIPERHALS.
