 36 pens versie van Geekcreit® nodig.

+
+HENDI:
+
+HendiControl printje wat ontworpen is voor CraftbeerPi. Heef twee signalen nodig:
+
+  - On  - inschakelen regeling, schakelt de potmeter uit.
+  - Pwr - PWM signaal. Maakt regelspannig 5 Volt is 0% en 0.8 Volt is 100%.
+
+In de bestaande driver de loopsnelheid houden zoals die is.
+Toevoegen een PWM signaal lijn. Deze volgt het omgerekende geinverteerde vermogen.
+Afschakelen HLT wanneer power boven totaal vermogen 3000 Watt uitkomt.
+Hiervoor moeten de vermogens juist zijn ingevuld.
+Timesharing met HLT is geen optie door de iets trage reactie van de Hendi.
+
+Welke pin voor PWM output?
+ - GPIO0. Mag niet naar 0 volt getrokken worden tijdens boot. Dus een PNP/NPN
+   driver inverter. De pin mag wel naar 3V3 getrokken worden.

+
+Wat is de frequentie van het signaal?
+Extra waardes in de hardware profielen.
+ - Bovengrens afschakelen HLT, default 3000 Watt.
+ - Ramp power voor naar koken gaan, boilpower is er al.
+
+Wat doen we met maisch verwarmen, limiet 1 graad per minuut? Of is de
+max maisch power setting genoeg?
