Xloader

 

[CadiBrewer]

@day_trippr had the same problem with the knock-off Nano I sent him. With the 2.10 hex loaded from Xloader, he went into the BrewPi software and reset the eeprom using the reset feature in the advanced settings. The error log still shows that there was a problem loading up the hex, but everything worked and the devices could be configured from that point.

Edit: Here are his notes for posterity's sake:

I had loaded 0.2.4 on the Nano clone and that version predates the "Factory Reset" function that showed up in 0.2.10. So I couldn't clear the eeprom until I loaded 0.2.10 - which I did using Xloader on the peecee.

Once I had that hex file installed I was able to use the "Factory Reset" function successfully. Still will not load hex files from within BrewPi (but I could live with that) but with the eeprom cleared I was able to power cycle the Nano and BrewPi could find it each time.

As well, I was able to install and configure a few suite of devices - all eight possible, including 3 sensors, 2 relays, a Fan, a Door Switch, and a Light. Was able to add them all in one shot, too.

Then I tested everything: Cool and Heat relays, all the sensors, the Fan, and the Door Switch and Light (with both configured the Door Switch will toggle the Light).

Then I switched out the USB connection for an HC-05 and that came right up.

Sooo....Everything works! That has to count for something!

Yes

I'm getting closer. I'm able to run off wifi. I can see the nano's leds flashing when I hit reprogram controller.

Just a quick question, I'm using Thorrak's amazing ESP8266 build and recently had LCD scrambling. I read from circa. page 70 of this thread, where there is mention of LCD scrambling, and then not a big mention of it after that. Is this an issue for anyone still? Cheers

I used to get it all the time using a mechanical relay, none at all using an SSR, I don't think we ever truly got to the bottom of why some scramble and some don't.

 

[alexlark]

Yea I was going to PM you and ask if you were still using SSRs

 

[Mikmonken]

On the brewpi I use with the LCD I do yes, but I find as my fermentation chamber is in the cellar I use my phone to get the temp more often than not. So I use the cheaper relay and don't have an LCD attached.

Just a quick question, I'm using Thorrak's amazing ESP8266 build and recently had LCD scrambling. I read from circa. page 70 of this thread, where there is mention of LCD scrambling, and then not a big mention of it after that. Is this an issue for anyone still? Cheers

It's endemic to the DM2004, unfortunately. There's something on that display board - or inside the HD44780 controller - that is susceptible to voltage noise. And the versions that sport the I2C backpack have the same problem, so it doesn't have anything to do with the interface.

iirc, @ame came up with a hack to the BrewPi hex code version 0.2.4 that executes the LCD initialization routine every so often and thus clear out any gibberish. I don't think he did the same with the latest/0.2.10 version...

Cheers!

Ok, WTH? Someone's hardware having a stroke?

Didn't let the magic blue smoke out of the pi. Do you think I should format the sd card and start over?

Not based on what you've posted - didn't you say you had it working over Wifi?

Yes - seems like the nano and pi are not talking to each other. The nano's leds will respond when I hit the reprogram controller button on the brew pi screen.

Use Xloader to install the hex file.
I was never able to get the Nano clone loaded using the BrewPi gui.
Then use the BrewPi gui to reset/clear the eeprom and you should be good to go...

Cheers!

[Then use the BrewPi gui to reset/clear the eeprom/QUOTE] I Tried that a couple of times. what setting in Xloader?

I actually used the Uno/Mega328 selection right below.
The chip is a Mega328 either way, I figured the hex file was generated for an Uno, so...

Cheers!

I tried using the Uno selection the first time but it was taking forever and I got impatient and pulled the plug. I did get a steady short red blast from theTXD LED so it must have been doing it's thing.I'll try again and let it go till it stops

Back in business. Swapped out the nano with one from a different supplier and everything works. I'm going to try and reload the bootloader on the other nanos just to see if I can get them to work. Now to fire up Bluetooth.

@Mikmonken any chance of a photo of your build with SSRs?

are you after the wiring?

My SSR Brewpi actually acts as a Sousvide, so doesn't have anything attached on the cold side.

but in terms of wiring this gives you a good example of how it should be wired.

then going from the SSR to the Arduino ground goes to ground, and then the + goes to heat or cool pin, you don't need to connect to vcc pin from the SSR.

Cheers, just wanted to gauge how big they are compared to the 2 channel relay boards. Not sure I've got the space for 2 SSRs.

 

[Mikmonken]

One SSR is about the same size as the dual relay. View attachment ImageUploadedByHome Brew1496935389.225541.jpg

Cheers, the SSR looks huge now! Lol

Does anyone think these are any good as a compact solution? Only 2a lower than the mechanical relays, my calculations say they are OK at 8 amps. Am I right?

80 watt heater - circa. 0.34 amps
200 watt fridge - circa. 0.86 amps
230/240VAC UK Mains

I've purchased one of the 8A SSR boards. I'll report back once received. At 8A this should be OK for the startup amps on a fridge. Hopefully the form factor will allow an easy swap for Sainsmart users IF it reduces/stops LCD screen scramble.
