Found a bug in integrator clamping anti-windup stopping integral action when needed. I will post an update soon. edit : New version available (v1.6.1) : bugfixe : - Integrator clamping anti-windup is now functional and work pretty well ! Zero temperature overshoot on my RIMS !

New version available (v1.6) : Added : - Filter on derivative only - Integration clamping (better than integration static saturation) Lot of bugfixes

Delete PID_v1.cpp and PID_v1.h in your utility folder. I've modify Arduino pid library and change the name to PID_v1mod to keep those libraries separated

After a lot of tests with PID filtering, I choose to modify my library... I will replace PID Output filter by a derivative filter (filtering applied on derivative block only and not all PID) PID Output filter combined with saturation worked great but causes a lag and, hence, a weird and brief...

New version v1.5.1 Debug : - first PID value was invalid

New version available (v1.5) : Debug : - debug : PID output saturation moved after filter (it was causing a very slow regulator) Added : - set point, timer and mash water values are remembered after entire cycle is restarted

New version availible (v1.4) Lots of changes : - Temperature is maintained when time is elapsed (until KEYSELECT is pressed) - Lot of alarm debug - Serial monitor warning in identification tool - arguments in setInterruptFlow to set lower and upper bound of flow rate (because it's not...

That's what I thought... For now, heater is shut off when time is elapsed. I will change that soon ... Thanks !

I was brewing and was stuck with a dilemma : Is it better to stop heating when time is elapsed or maintain temperature ? Cooling could be problematic if your mash is too much cooled and you have to re-heat it a lot for mashout or alpha-amylase temperature level. Or even worse, bacteria...

New version available (v1.2.1) - added : support for multiple regulator (up to 4) useful for diffrents mash water quantities It replace an old feature that let you set settings for SIMPLEBATCH and DOUBLEBATCH I was brewing a strong old ale 6 gal batch and noticed that mash water needed was...

New version available (v1.1) DEBUG : -FLOWUPBOUND = 5 L/min -CRITICALFLOW = 1.0 L/min -flow sent over usb didn't had limits

Hall effect flow meter needs Arduino 5V and GND. So, if your flow meter follow the "standard colours", red wire should be connected to 5V and black wire to GND. The last wire should be connected to one of your interrupt pins on your Arduino. If it's an Arduino UNO, it should be connected to...

I have made a lot of test with my RIMS in the last days. The next release is no longer beta. Hence, new version available v1.0 : debug : - _refreshDisplay() when switch screen - temp ADC >= 1021 is considered like unconnected thermistor

Yep, you're right, sorry ! I don't know why it is still there but anyway... New version available (v0.8.5) : bugfixes : - rimsBasic.ino now compile - IdentRims flow warning LCD refresh rate = IDENTSAMPLETIME

If you download last version, you shouldn't have this bug in rimsBasic exemple. If it's your own *.ino file, i've made a few changes in methods : - setTunningPID() replaced by setTuningPID in Rims - run() replaced by startIdent() in RimsIdent - optional arguments stopOnCriticalFlow=true...

new version available (v0.8.4) : bugfixe : - sometime, PID calculation was skipped

new version availible (v0.8.3) : debug : - flowWarning LCD refresh rate = PIDSAMPLETIME

New version v0.8.2 Debug : - better timing in Rims and RimsIdent : if sample time is a bit longer than it should be, entire time line is no longer shifted

New version available (v0.8.1) major bugs fixed : - debug : ssrRefresh each iteration - debug : set point filter initial condition = operating point

Found some bugs with Rims class and Timing...i'll post an update soon
