I did install the temp sensor near the load cells themselves as a means to get an "average" reading for temp such that if the temp was high, it would be appropriate for the load value to be compensated for that temperature. It will be at your discretion as to where this temp sensor placement...

No problem. I really need to get back to finishing my scripts so I can actually brew something one of these days :).

I know you guys will. I just wanted to provide the info I had to save others and yourself some time as more complete testing had not yet been done (i.e it is beta). I'm still using the MEGA, so the Grand Central being beta is no problem. Once the issues are ironed out, I will toss it in the...

I did notice that if I bent the 3.3V pin, the A4 &A5 voltage dropped to 0.4V. That is, as it turns out, because I had my two pull-up resistors for pin 20 & 21 powered through that on the ethernet shield on the bench. So interestingly enough, if I pull the resistors from 20 & 21, the voltage...

I took some readings with the Seeed Studio installed with an Arduino Sketch and with BC firmware. With BC firmware it appears only A4 and A5 are pulled up to 3.3V, all the others are at around 0.2V. Even though A4 & A5 are pulled high, when I connect a voltage generator to them, they track the...

Another Adafruit Grand Central M4 update. I had previously confirmed that all analog inputs were working properly on the new board I received (via the Arduino IDE) so I soldered on the headers and tested the board with BC v45 E firmware. While the serial connection is not working with BC, an...

I received my new Grand Central (headerless) and it indeed acts like a properly functioning micro should. Testing via an Arduino sketch shows that all the analog pins are working properly. I can flash the BC firmware to it with no problem as well but serial communication to BC is spotty, at...

Well, that would explain that phenomenon!

OK, I get it. I simply added that bit to my sketch to keep the result clean but after testing A0-A4, the GC is no longer being recognized so I cannot communicate to it to get readings. Unless it is in bootloader mode, it is not seen as a Com port. I can load sketches and BC firmware in...

Alright, I am doing some testing of my GC with wonky analog readings in BC. I pulled it from the enclosure and it is being tested bare on the bench with an analog voltage/current generator and I was hoping some folks out there with more experience than me could give me some direction. I...

Thanks Die Beerery. I appreciate the offer. Let me give soldering the headers on the headerless unit I have coming in this week. If that fails, I might be in a pickle and take you up on your offer.

I never was able to figure out what exactly was happening as I just wanted it to stop and found it was A2 that was making everything go haywire on power up. Indeed, I could give that a go in the IDE as well. I will see if I can fit that in.

Hey BrunDog. I'm looking for an opinion on the fitness on my GC micro that I have been struggling with. I have most things ironed out but my analog inputs are a bizarre mess. While I have previously stated I had enough analog inputs "working" if I simply ignored the ones that oddly killed...

Sorry BrunDog. Bone headed thing on my end. I had to change the PWM pins for the pumps feeding the AA-1 as they were not putting out PWM. I forgot that the values were "Raw" and when I put in 100, it was not all the way on. 255 is needed in this case of course. I pop in 255 and I get 5.0V...

I noticed on the Adafruit website that the GC analog pins are also digital I/O. Is this unique to the GC and is that a potential area that is creating the weird problems I am having with A4 and A5 (actually A2 is weird as well)? The thing is, A2, A4, and A5 do all function properly as an...

Doing some testing on the GC, now with the pull up resistors on 20 & 21. Firmware install and network setup is super smooth with no issues. Termite gets a response back from the board quickly and everything works like it should. For network setup after the firmware install, I did not need to...

I totally love the idea of the GC but not so much the actual GC. Like you said, they have struggled a bit with quality. Which is odd for Adafruit as I understand it.

I'll see what I have and give it a go at some point. I do need to sleep tonight...it has been a few days :). Why not throw another odd ball out there! I uploaded the serial firmware and that went well. BC said it was connected but the communication window would stop showing data coming over...

Sorry for all the posts but I'm not sure what is going on with the Grand Central as it is acting more and more alpha the more I try to make it work. The GC will occasionally not "boot" correctly as far as I can tell and the Neopixel turns red and power cycling doesn't resolve it. I have been...

OK, one last question for (for the moment). I see a number of things to potentially address this concern but I suspect there are some ways that are better than others. The problem I am having is that I have a 3.3v PWM signal coming from the Grand Central controller going to the BruControl AA-1...
