It uses +; the PINSELx Register to Set the Pin Function to GPIO. +; Then, it uses the FIOxDIR register to set the +; direction of the pin to output. It also contains functions +; to write a digital HIGH or LOW to these output pins. It uses +; the FIOxCLR AND FIOxSET registers to clear/set the +; port bits respectively. Refer to the Pinnames.h +; file to see which LPC1768 pins a given mbed module is +; connected to. Then, refer to Chapters 8 and 9 of the +; LPC1768 User Manual to acquire information on the GPIO +; registers and their addresses. +; +; Example: +; LED1 is on GPIO port 1 bit 18 according to Pinnames.h +; For this bit: -the PINSEL3 register determines its pin function +; -the FIO1DIR register determines its pin direction +; According to the LPC1768 User Manual: -PINSEL3 is located at 0x4002C00C +; -FIO1DIR is located at 0x2009C020 +;

+; This file contains ARM Assembly language functions to
+; drive a 7-segment LED Display (Kingbright SA03-11HDB).
+; This library uses a switch statement on the input
+; register (R0) to set or clear each corresponding lead
+; of the display. NOTE: The 7 Segments of the LED display
+; must be connected to pins p11 - p17 of the mbed digital
+; I/O. For further help with understanding this file,
