Hi,
I tried #include <stdio.h>,but in vain.
example code:
Msg->strength(rssi) is uint16_t variable which is by default displayed in
hex like shown below:
ReceivedMsg->data[0] = Msg->strength & 0xFF;(MSB)
ReceivedMsg->data[1] = Msg->strength >>8; (LSB)
I have to get the 1's complement of Msg->strength.and then convert it into
decimal.I tried like this.
ReceivedMsg->data[0] = (Msg->strength & 0xFF) ^ 0xFF; ReceivedMsg->data[1] =
(Msg->strength >>8) ^ 0xFF;
I get the 1's complement but i can't get its decimal equivalent.Typecasting
didnt work.
Many Thanks,
kishore
