Hi,
We would like to issue a command serially from master to slave but we don't know how. We are trying to interface a temperature sensor to the board and we got stuck on how to control the clock pulse given by the Master so that we can input 8 bits one at a time. Does this clock pulse have to be controlled by a delay or do we have to use some PWM? Once we establish this, how do we actually indicate that one bit per clock cycle should be processed at a time?
Thanks!
"we must use pwm as master?"
Why do you feel PWM have anything to do with this? What datasheets have you read that indicates a need for PWM? More importantly - you haven't even mentioned what processor. Don't you think the actual processor will affect any answer of what to use to generate a specific signaling?
Next thing - are you part of a tag team? In that case, you should be able to bounce ideas with your tag team partner. Exactly what conclusions have you come to, after carefully analyzing your situation?
