Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Ok, it looks to be related to nano2 code using a particular I2C LCD library.
I write to the LCD memory in the most direct manner possible.
I do not use LCD.print(blah,blah..)
This is a hangover from when I had all code running on one nano
so needed something fast when writing to the LCD.
I could not spend much time doing this before I had to service
PWM interrupts.
So I wrote LCD text, one character at a time, direct to LCD memory
bypassing the arduino LCD library overheads.

I wonder if the new LCD you have has a different controller and so the
way I do things will not work, ever, with your new LCD.

I need to change the code.
Maybe I can find the time to rewrite nano2 to use
the standard arduino LCD methods this weekend.

I got a couple of torroids for you so that will cheer you up.

BTW I had two internet purchased lcd's, I thought they were the cause so got one from jarcar and it too has the same issue, so all three display the same trait.

Very frustrating how they appear to be made differently, you would think an I2c adaptor did just that and they all did it the same way, but clearly NUP.Edited by renewableMark 2019-03-23

  tinyt said   For the LCD that I purchased, I cannot get the backlight on unless I do a hardware mod or add the 'setBacklight' as follows:
lcd.begin(20,4); // LCD stuff
lcd.setBacklight(255); // <<<
lcd.clear();


Just noticed when this is added the nano lights up, loads then it briefly writes NANOVERTER, on the screen then it goes blank.

Without that extra line it just lights up. loads the nano then goes blank.

Mark,
I did a quick and brutal hack of nano2 code so that it works using the same
libraries as Madness regulator

It's not good, but it works.
Not the sort of code I want to show the world.

Put this into nano2 and see if you get a display.
The backlight might come later.

Loaded that and it highlights
lcd.init();

Mark,
I found what libraries are needed to run Madness's program, got them
and made MAdness's program compile OK.
Then I changed nano2 code to use the same LCD library that MAdness uses.

It then compiles and runs fine.
The library you need to make sure is installed is
"LiquidCrystal I2C" by Frank de Brabander version 1.1.2
This is the library I use now.

If you have problems compiling, maybe avoid posting the entire error output.
I know I did not read any of it. It was clear the problem is due to library links.

Best code, using the above mentioned library, and so, likely compatible
with most 20 x 4 LCD with I2C:

Thanks,
that loaded ok, when the sketch is loaded the screen breifly said "NANOVERTER" then the screen lights up without any writing and the OC light comes on.
I have the reset (NC) plugged in. hit that a few times and nothing. Adjusted the trimpot then hit the reset, still the same, red light on constantly.

If the OC light is on, the inverter will never run.

Can you connect to the menu, via the serial monitor?
type "?" and press Enter, get a menu?

I am concerned that nothing much is displayed.
Even when shutdown, the LCD should show stuff.

Tried that, it just restarts the nano, does the same thing and doesn't display the menu.

maybe this nano is broken?

you could pull it out of the socket, power it via the usb cable
and upload the software again. open the serial monitor and see what you see.
(need to wait at least 2 seconds after connecting via serial monitor
for any response..)

or maybe something on the board is stopping it from working.
first things first, let's see if the nano is OK or not.Edited by poida 2019-03-24

OK running the house now, tripped a few times due to scr.

To increase the allowed current turn the trimpot anti clockwise.

So wave is perfect on everything apart from the dreaded inverter air con as below.



So how to smooth that out??

Tinker previously said to remove the ferrite, I'll give that a go.

Failing that what would smooth out the voltage to stop/reduce these spikes being placed on the machine?

Choke on air con 240v supply?

Big caps on 240v inverter output?

Would not have a clue Mark.

So many issues it could possibly be. But if the aircon is the only load that does it, that is probably the place to start looking.

I think I might run the aircon off the grid, and look at the current waveform as a first step.
Cheers,  Tony.

Yeah tried that, it's perfect running with grid.
