I just changed my tft. It was an ili9341_16 and I changed it with a sainsmart ssd1289 because ili had burned some lines.
The problem is that I can't make dimming work on ssd screen. Dimming was fine with ili tft but when I connect it to ssd, the screen flashes and I can't see raw images.
If I connect the tft's led backlight directly to 5v it's fine.
Any help?

Question

Has anyone managed to run it on DUE? Problem almost with every library.

Did you check the pin-out of both screens?

I might be dutch but I don't have a dutch scape.

I gave the screen to a friend to try in his iAqua and it is working fine.
I can't understand what is going on...

Maybe a bad header or something?

The strange thing is that ili is working fine.
Ssd is working "almost" fine if I connect pin19 from tft shield to tft led backlight, but refuses to boot if I connect the cable from dimming circuit.
There is something in dimming circuit that affects SSD screen and doesn't affect the ILI one.

Led light less bright when connected to controller

Hi All,
Facing some issue with the LED lights have build along with this controller.
I have 15x3w LEDs, 3 each hooked to mean-well LDD700H. 12v8amp PSU.
If i connect PSU directly to the LDD, i get enough light intensity.
But when i connected through the controller the LED doesn't give 100% brightness even though i keep the light bar on the controller to full 100%. The light is not even half of what i get when connect directly to PSU.
Help appreciated.

Did you tie the ground of the psu to the ground of the controller?

Thanks Fietsenrex,
Yes i have connected the ground of PSU to Arduino as i am able to control the intensity of the LED's from the controller. The issue is if i set 100% intensity on the controller it is still very low as compared to directly giving 12v to the LDD700H. This LED are Cree 3W.
I read the current on the output of LDD700, its 690mA when powering directly with12v(without PWM) and the same when i connect the controller(PWM) i get just 20mA which is way too low.
Need to know if their are any settings in the code.

There is a boolean in the code stating if you use the PCA chip or direct PWM, you could try to check that part

The booleans are set to false.

boolean lightCSP = false;
int maxIR = 100; //using e-series
boolean PCA9685Installed = false;

That is strange.
What is the output voltage of the controller in various settings of light intensity?

Btw i Think i set the PWMmax to 225 But i have to check my sketches....
That could be an issue if it is set incorrectly

Does the 20mA change at all with the setting (ie changing from 0 to 100%)? Can you measure the voltage at the PWM pin at 0, 50% and 100%?

Also, which controller code are you using? The original iAqua or one of the others posted?

Wow, still @MrMan had this post folow up, i was wishing that this is my beginner arduino project, but a lot had been done, respect to every one, Mr AH, you suck, if it was'nt you, this project would have die, but it still live, but Mister O2 and those that have utilised these theories of automated aqua, are very commercial, but you are the great, if i were you, i should have a licensing terms that who ever try to copy this and that will be not allowed, but a very good hoby for my life. your exact mind is me, but not like the other guy who just try to commercialize every thing they find, big salute to you alute you, 2014-2017, its still alive

Bump: @mrman, thank you for still supporting this post, you rock

Bump: And i think this post is all for those automating your aqua, i love you, i would keep up with this post
