Hi, I am attempting (and failing miserably!) to convert the original sketch used to output the results from an LTC to a TFT display. I can get the serial output version of the sketch to work fine.
The TFT version of the sketch uses a library
As the guru on TFT devices and the range of drivers etc used, and my belief that you were probably heavily involved in the creation of the original TFT LTC script can you point me in the right direction on modifying the sketch to use the new TFT libraries.
Thank you in anticipation,
Want more information on 4 5 inch uatr tft lcd? Feel free to contact us.

David,
Thank you for your prompt response. I purchased this on EBAY:http://www.ebay.co.uk/itm/2-4-inch-TFT-LCD-Display-Shield-Touch-Panel-ILI-240X320-for-Arduino-UN-D1E3-/?_trksid=p.m.l.c10#. Whilst the seller says it uses a 1L controller it doesnt, having read your posts about the stuff sold on EBAY and using the test in MCUFRIEND_kbv it identifies it as a HED. Setting this as controller in the Library code (.cpp file) it runs through all the graphicstest_kbv tests perfectly.
The sketch I am using is as follows:

I also have a serial out sketch which works fine. If i had carried on failing so dramatically i was going to try and convert this to output to a TFT display :o
Hardware: Arduino R3, LTC on breakout, TFT panel. I have had the DVM working fine and the TFT panel working fine , just not with this sketch.
I don't need anything clever on the display:
| |
| PSU N | N = Constant 1 or 2
| |
| XX.XXXX Volts |
| |
| X.XXXX Amps |
If you can help me with the basics I am sure I can tart this up. As I said if I could get a copy of the original Library (UARtLCD so I could compile the sketch I have, I am sure I could have solved this myself, however I am most grateful for whatever help you can give.
I have to add some logic to the DVM so I can switch the input between the two measurements being made (Voltage and Current). This will require me to hang an output onto the arduino/sketch so the input matches what is being displayed (or vice versa).
Once again many thanks for the help
Don
