Hi, I was using CCS v7 for MSP430.....I was getting the following errors:

 #225-D function "send_cmd","delayms", "LCD_Init","send_string" declared implicitly......for this i have refered "processors.wiki.ti.com/.../225"......but i didn't get the prototype .h file or a declaration files to add before these........kindly help me in giving these declaration files

Thanks in advance,
