Hi, If I'm not mistaken, you can bit-inverse a value with the ~ operator (tilde). Something like "complement = ~value;". If this doesn't work, you could also use the xor operator (^) and one of the operants with all bits set to 1:
uint8_t value; uint8_t complement; //... complement = value ^ 0xFF; Cheers, Urs ram kishore wrote: > Hi, > I need to find 1's complement of the incoming hex message.How to add > #include<stdio.h> to my application? > Is there any alternative way of doing this? > > Regards, > Kishore _______________________________________________ Tinyos-help mailing list [email protected] https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
