What I was hoping is that from the shield, that not all 40 pins required on the long connector so I can use a 40 pin ribbon to connect the minimum amount of pins instead of having to use 3 ribbons.
It can be done.
25 pins for the TFT and LCD Shield, and the power feed - max of 6 pins(?), 31 in total.

Cool ! I'll give it a go.
Just waiting on some 2.54mm dupont pins from Hong Kong (eBay)

According to that link, your screen uses the SSD1289, so it matches the latest Jarduino Beta release without having to make any changes.  Did you perchance try different modules?  Usually, the best way to troubleshoot screen issues is by uploading some of the example sketches from the graph16, utft, and/or touch folders. Once you can get one of those example sketches to display and work properly, then you know what parts of the code you need to change in the Jarduino...

Woohoo! After a couple days of reading similar threads and some trial and error I found out that just changing on teeny bit of a line fixed the problem. I'm kind of embarrassed it was so easy. On line 92 of the V1.1 code I changed the line from:
ITDB02   myGLCD(38,39,40,41)
to:
ITDB       myGLCD(39,39,40,41, ITDB32S) and everything now works.
Great little program Jamie! Everything looks cool. Will be donating and getting the upgraded version!
Thanks for the help!

Jamie what frequency is the pwm set to on your sketch, worked out drivers run fine when under full power but they all start failing when the higher power led driver start to dim the white up or down, replaced the arduino and around 6 drivers so far but all keep doing it just about at a loss now lol

For the wavemaker, it's set to 25 kHz, but for the other PWM channels, they run at the default 490 Hz.  You can change some of those channels, but not all of them as it will affect the millis() and delay() functions which in turn will adversely affect how the program runs.  Do you keep losing drivers on a particular channel?  If so, which one(s)?  Also, do you know what frequency range your drivers specify?  I may throw in a feature with the next release that allows you to change the frequency on some of the channels if it's something that will be helpful.

Hi people hope you can help as i have no idea what im doing?

I have just loaded Jarduino v1.1 onto my arduino and it loads fine after adding "ITDB32S" to line 92.

I get to the main page and touch the screen and it takes me to the options page, from there i can do nothing.

Any one got any ideas?

Thanks Baz

Did you clear the EEPROM?

Yeh i cleared the EEPROM.

At first when i uploaded i just got a white screen so i entered ITDB32S and that sorted that.

so then i ran the calibration sketch found in examples and that came up with 0, 0.00, 0, 0.00 and said at the bottom i have a 2.4"????

the touch screen worked for the calibration sketch but not when i reloaded V1.1

Just about baffled now jamie it was running fine until recently, last night i tried the pwm white channel on just one pwm driver lasted around 5 mins on the test array setting then heard the driver pop then no more pwm adjustment.

When you cleared the EEPROM, did you change the 512 to 4096?  I suggest you try to run the  EEPROM clear again, wait till the LED lights up on your Arduino (approx 15 seconds), then re-upload the Jarduino.

Very odd.  Do you have your drivers directly connected to the Arduino, or do you have some kind of Mosfet in between them?

Yes i changed the value and have tried it all several times i dont get it??

I can run both the ITDB02 and UTFT calibration Sketches but when io go to do the button tests there is no response?

arduino to driver direct, thinking of using the Optocoupler but not to sure if it will do the job, the 1,3,5w driver work spot on never failed once its just the 10w and white pwm ones

Ok fault diagnosis time,

blues, reds, moon, uv fans all run off one 36v 11 amp psu on to the sure electronics 5w, 3w, 1w drivers and dc-dc converter for the fans, all works well on that channel

the 5 x 50w whites and arduino run off the other 36v 11amp psu the arduino runs from 7v from dc-dc converter all the 10w white pwm dimmers seem to be failing.

Shoved a separate adruino set up on with a dedicated 50w led driver and a 5w pwm dimmer all is working well, changed the 5w for 10w driver, again all is working well.

Now i have put the feed from the white channel psu to the 10w led driver and feeding it from the separate arduino just linking the neutrals forgot to say the arduino is been powered by a 12v sla batt. so that eliminates the psu been faulty.

Next steps separate psu for arduino getting rid of the dc-dc converters

kind of thinking something to with with a group loop going on



May invest in some of these

I like the RECOM drivers better. Have yet to hear of one failing. I use the RECOM  RCD 24's. They allow up to 36V input.  The new 48's go up to 60V!
