there is a program of TSOP but an error has come that is ../newknp.c:119: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'void'
and a warning c:/winavr-20080610/lib/gcc/../../avr/include/util/delay.h:85:3: warning: #warning "F_CPU not defined for <util/delay.h>"
pls give some help i want ....
