ummm.. I removed my sunfounder Mega2650R3 w piggyback 5500 from the screwshield in my production panel, took to my office, loaded 45O, put it back in the production panel and no communication... took it back off and programmed to 45K, returned it to the panel, and it worked. I repeated this...

I hooked up another analog input (with voltage divider ) direct to the output of the analog amplifier output driving the valve signal (I tried direct pwm to analog input, but it jumped all over the place due to sampling, so I used the filter built into the AA-1), here is valve position(blue) vs...

Here is the graph of the valve position feedback. The PID output is maxed at 51.4 with a combination of the 3.9F * Kp providing the 1.4%, and the Ki with Max integral set to 50% providing the 50%.. The calculated and displayed PID output is steady at it's maximum, however the *actual* output...

@BrunDog - I am debugging a weird issue, my 45K Mega seems to be outputting a pulsed voltage as seen on a multimeter whether or not I have the PWM switch enabled or not. (it seems to be doing 'duty cycle' all the time). The PID device is on output 2... the blue wavy line is supposed to be...

can you show the properties of the PID element? if you don't have the Input set in the control section, you will get the ----

OK, I am not sure what FW my Mega was on, as I could not get it to respond to termite, so I upgraded it to 45K, and it now works... this is the first time the PID for cooling has acted like the Sestos it is replacing... I ended up using Kp of 0.8 and left Ki and Kd at zero, I tried to use Ki...

I am trying to get my PID working correctly for PWM cooling with water flow via a valve, both PID's shown here are default other than Kp being set to 10, and PID 2 being 'reversed'. Why is there no action on PID2 when the input crosses the target? Why is it -255, that seems very unorthodox...

Regarding 2/3/4 wire operation, Adafruit in their documentation references programming the actual MAX31865 for the type of RTD And the datasheet says to write the D4 bit of the configuration register to match the type of RTD... What is the BruControl implementation doing here?

I would really like to see the 4-channel 16-bit RTD module working...

I like to get OEM automotive grade (TXL/GXL) wire from a place like wirebarn, the stuff is super high quality and great to work with... they have 10-color packs on eBay for a reasonable price... Best $12.50 you ever spent

the best advice I can ever give anyone building a brewery on an existing floor: Flood the floor with a couple hundred gallons and see where it goes... then cut and pour your brewery floor there... then the entire building will then survive a large spill with ease and you won't be mopping up...

what is the accuracy drop of using a 4-wire as a three wire? 3 to 2 is pretty big, but 4-3 is not that big right? 4-wire seem to be very uncommon now as far as what I see out there... and the wiring change is not really like one jumper, it is like three per RTD. I think 4-wire are more...

ESP is super inexpensive and ubiquitous (I love the Wemos D32pro with tft port, but they could stop making it tomorrow...) RTD amp boards are kinda bulky, and require mods, on-board wired for 3-wire is my preference. 4 needed, 8 is overkill Screw terminals for rtd and 1-wire should be tiny, not...

I did it a decade ago, it was worth it because even fined beer still deposits a layer on the bottom over time, and I may only have one beer from each tap every few days... but I would swap back for full length ones now, because I use them in a distillery and want every last drop...

I think either will 'run a motor' from control in BruControl, but you will be in charge of positioning accuracy...

shorter link to device mentioned, https://www.amazon.com/dp/B077WTTTFH/ I think not without custom firmware, the best bet to integrate into BC is to make it so a single analog or digital output can drive a discrete motor controller that can take that analog or 1-channel digital signal an...

interesting, just saw this seeed studio Wio Terminal: ATSAMD51 Core with BLE 5.0 & Wi-Fi 2.4G/5G Dev Board on amazon for $38.99

The CAN interface is interesting... really interesting.... IR interface also... the relays are not powered when on battery, which is OK, I guess... whatever you were going to switch with them would not have power anyway... the external antenna and full GPIO make my ESP8285 SonOff Duals very...

I have 2 RP-3 connected to a single ESP32 this way, and sometimes on power-up I have to disconnect one before the ESP becomes reachable, then connect it and all works fine... the ESP32 is powered via USB, and I need to ensure I am using the 3.3v pin... multiple other ESP32 variants with...
