Terrarium programming help

[scott3t]

Built the Terrarium a while ago and was able to get a delay and a reverb to run on it however I can't seem to get the LEDs or foot switches to do anything. I suspect the Terrarium header may be wrong or missing in the code. I need any type of complete tested and working Terrarium code. I'm using the Daisy Web Programmer.
I have checked all connections from the Seed and traced connections to FS1, FS2 as well as the LEDs, R5 and R8. From terminal 39 to the LED anodes I get 6.75 v. From terminal 40 I get connection to the LED cathodes. The seed power led lights up in both USB and with 9V.

Check out some of @keyth72 build reports on the terrarium, that guy has done some pretty cool stuff with the daisy seed and I believe has even posted some GitHub links in at least one of them.

@scott3t Are you trying to load up the default Daisy programs using the Daisy Web Programmer - or programs that were written specifically for the Terrarium? I believe the Daisy Petal uses different pins for the footswitches and LEDs than the Terrarium, so they may not work if you are loading up the default Daisy Petal programs.

If you have not tried loading up a .bin file written for specifically for the Terrarium.....you can download one (like the one for the Rhythmic Delay here) and then use the "Or select a file from your computer" section of the Daisy Web Programmer to load it onto your Daisy Seed. If the footswitches and LEDs still don't work you may have to continue to look for hardware issues.

I tried that and have the same results. With the Seed removed from the Terrarium, I have 2 of the chips on the seed getting extremely hot.

two chips on the seed, or two chips on the terrarium board when the seed is removed?

Two chips on the Seed when it is removed from the Terrarium. It also get hot when installed on the Terrarium as well.

 

[zgrav]

i don't think those chips should be getting hot when remove the seed and power it with the micro-usb port

I can still program it with the Daisy web programmer but yeah it doesn't seem right that it gets hot

I suggest sending the company an email and ask whether you should get an exchange. I had one defective Seed that they replaced last year.

Thanks I was just looking into that

I have received another Seed from Electro-Smith and still can not get any of the code for Terrarium to work. No sound at all. From the Daisy Web Programmer, I got a Daisy Petal MultiDelay or Tremolo to work but the LEDs and foot switches do nothing. I can engage or bypass the delay/tremolo by flipping the mini toggles and the pots work as well. I have traced the from the Seed to the switches and LEDs as well as the grounds All are good.

Hmmmmm, that is strange. Do you have some close up images of the pedal guts?

I'm not sure why the audio would work for the Petal programs and not the Terrarium programs, they use the same audio pins on the Seed. The Petal & Terrarium use different pins for LEDs & footswitches - so it makes sense those would not work when loading up a Petal program. I made the attached pinout comparison a while ago, but I think it is still right.

Do the Seed pins for the LEDs change voltage when the LEDs are supposed to be on/off? If they do maybe the LEDs are backwards? I am not sure why the footswitches would not work, but you make sure the voltages for those switches change too when you press a switch.

I get no Voltage on the LED pins using Petal code or Terrarium code. All of the Petal examples work with the knobs functional but no LEDs or Footswitch functions.
Checked my LED's and I'm pretty sure they are installed correctly with the smaller anode to (A) and the larger Kathode to (K). I applied 4.5 volts to them and they light up

 

[scott3t]

I have decided to order another board and will transfer most of the parts and replace the resistors and capacitors

the smaller anode to (A) and the larger Kathode to (K).

This is backwards. On an LED the Anode is the longer lead and the cathode is shorter

Thanks PJS, because I had snipped the ends after soldering , I was referring to the nodes inside of the LED
