First, let me just say I have only made it to your 3rd IC programming tutorial video on Youtube, but I'm already using IC chips in my game all over the place, so thank you!!!

Unfortunately, I'm stuck in my greenhouse on mars during a storm with my (ingame) laptop and my greenhouse cooler is clicking on / off /on /off because it's right up against that maxtemperature.

What I used to do for my greenhouses a long time ago was use the "Schmitt Trigger" logic chip design, where you would create 2 memory chips with a Max and Min for each "side" of the loop (cool and heat). So in Logic Chips it was 12 chips to control heating and cooling..

I'm hoping to add a few lines of code that will essentially do the same thing... I really suck at this!!!! I found someone else's code where they do this with some math...

Edit: As my understanding grow's I'm going to mark this up a bit with comments for the benefit of others...

label d0 sensor
label d1 LoMem
label d2 HiMem
label d3 cooler
label d4 heater

start:
l r0 d0 Temperature # Load the temp from the sensor on pin D0, this is done by the " l temperature sensor Temperature" line of Cow's code

sub r0 r0 273.15 # subtract 273.15 off of whatever the current temp reading is

l r1 d1 Setting # He's using memory chips to get the min and max temps but Cow's code has it hard coded in - this one gets the low temp from a memory chip

l r2 d2 Setting # this one gets the Hi temp from the memory chip

sub r3 r2 r1 # subtract the set Hitemp from the set low temp and store into register 3
div r3 r3 3 # divide the result above by 3 and re-store that result into register 3
add r4 r1 r3 # add the number from above to the low temp setting and store to register 4
sub r5 r2 r3 # subtract the number from above from the hightemp setting and store to register 5

slt r6 r0 r7 # this sets Register 6 to 1 (true) if the currenttemp is less than r7 (but I dont' know where r7 came from ??

select r7 r6 r4 r1 # according to the documentation, Register 7 will be set to either the register 4 or register 1 depending on if Register 6 is a non-zero value or not. In otherwords if Register6 is zero it will set Register7 to be the value of Register1

### annnnndddddd... my brain hurts, I'll be back later ###


s d4 On r6

sgt r8 r0 r9
select r9 r8 r5 r2
s d3 On r8

yield
j start


I don't suppose this could be another youtube video in your IC Programming class??

Sorry I'm just so bad at this :(
