pic24f delay
Hai to all,
The code below for an lcd with pic24fj64ga002 and mplab c30 compiler gives me an error as
pic24lcd.c: In function 'cmd':
pic24lcd.c:28: error: syntax error before numeric constant
pic24lcd.c:32: error: syntax error before numeric constant
pic24lcd.c: In function 'data':
pic24lcd.c:41: error: syntax error before numeric constant
pic24lcd.c:45: error: syntax error before numeric constant
pic24lcd.c: At top level:
pic24lcd.c:50: warning: return type of 'main' is not 'int'
pic24lcd.c:94:2: warning: no newline at end of file
I could not understand where and why the syntax error occurs, can you please help me out.....
And also am I doing it in the right way???
Thanks,
siva
