Detailed Description
GPIO class for SJ-One Board or any LPC17xx CPU The pins on the SJ-One Board can be used as General Purpose Input/Output pins which can be attached to for example an LED or a switch externally.
Please see the pin labels on the board and then use this class to manipulate the pin(s). See the next examples :
Output pin example :
