environmentSimulator Implementation

[atmask]

#envSim Details

• Receives all pipe write FD from command line args

Thread A

• name_attach /dev/local/environment
• while loop: receiving actuator pulses and updating the stored state of that actuator in the process
• data receive in the form TEMP;UP or TEMP;DOWN or TEMP;OFF. TEMP and associated states UP DOWN OFF are defined in constants.h
• accessing the state of an actuator should be mutexed

Thread B

• Get mutex and check the actuator state
• if actuator OFF (OFF is defined in constants.h) then modify temp as temp+=randomNum(-1, 1) and push to correct pipe
• if actuator UP (UP is defined in constants.h) then modify temp as temp+=randomNum(0.5, 1)
• if actuator DOWN (DOWN is defined in constants.h) then modify temp as temp+=randomNum(-0.5, -1)
