Hi,
I am having trouble with my Maxim DS18S20 sensor which I am trying to interface with PIC16F877. To test the sensor, I am trying to transmit the temperature byte by implementing USART. I get some kind of output on the DQ pin, which I see using an oscilloscope. But the output that I get is 8 bits which are all ones, followed by an almost equal interval of the pin driven low and then it is back to its high impedance state. Another question I have is... if I am using a 4 MHz crystal, then one instruction is executed in 1 us or 0.25 us. Any help on this would be appreciated greatly. Thank you very much.
