Hi Guys,I am doing a project using LPC 2148 microcontroller based on ARM7TDMI(-s) Core.I am interfacing a keyboard to the PS2 port of my development board..My project is that If U enter the correct password using the keyboard, then one output pin should be HIGH and if U enter wrong password ,then some other output pin(probably one connected to Buzzer) should be HIGH..But Im unable to do it using a string of chracters as a password..I have only been able to do it as a single character password..So, plz let me know if there are some ways so that I can store the previously inputted characters in some variable or Register and compare the whole string with some predefined string of characters once the user has typed the complete string of characters..I have somewhere read that we cant use arrays in embedded C..So, whats the way out for my problem??
