Since the signal was well filtered, and the system had some "thermal inertia", that worked pretty well.īasically, this allowed Temperature, Temperature Setpoint, Hysteresis, Correction and Delay to be easily written or read by a Node-Red application over a serial interface, and also allowed for a simple "report by exception" capability. There was also logic (probably triggered in the "measure" routine) that would call print_temp_pv whenever the temperature reading changed. The command print_temp_pv _CR _ would return the current temperature as an easily parsed string, etc. For example, the serial command: 300 set_temp_sp _CR _ would set the temperature setpoint to 30 C. That was enough for a useful serial interface. for a total of 13 new (very simple) words.

plus a method for print_temp_pv, which would print the current temperature at the serial port. Basically, I created a set, get and print method for temperature setpoint, hysteresis, relay delay, and temperature correction. here are the routines that I created for the serial interface. I guess that most people will need a walk-through.įor whatever value it might have. The menu implementation is also a proof-of-concept for the application of reflection in an embedded application. This requires some more state awareness than what's now implemented. The nonsensical sentence above is courtesy of "GitHub Flavored Markdown" (the brackets in will be interpreted as invalid HTML elements -) - it's been pointed out an important weakness in menu.fs: the input key GPIOs are also used for the serial interface. It would be easy to use CRC16 for that purpose :-) If you need any kind of signal safety I would like to recommend sending TIM and a redundant signal (that's the bread-and-butter safeguard against stalled or corrupt transmission). TIM $4F AND 0= IF \ must be > 5ms \ => more than 5 chars through signal redundancy : controller ( theta - flag ) \ simple temperature control with hystesis & delay \ c.heat IFĬ.cool IF \ ( theta ) C.off SWAP 5ms (i.e. I did review the table that published but the input (A2) and output (M2:M15) cells he indicated in his comment on HaD did not seem to be linked to anything.

Probably every 5 seconds would be good to send the temperature as a typical cycle about 300 so about 1.6% error. I think I might have struggled to get that change.
I didn't expect you do all of my work though -).Īnyway, the logger is gone.
