3.2″ TFT LCD (new)
In my this writing i will introduce my new TFT LCD display.
I bought that screen because my previous screen was not good enough. It couldn’t run all UFTF library and technical support was not sufficient. So i ordered new one from ebay, sellers name is electronics_lee . It is 3.2″ touch screen (1)
first of all i only connected TFT connections without SD card and TOUCH screen pins.
My connections are same as at “UTFT_Requirements” files in page 2 and 4. (2)
Then i faced different problems at the screen. Some random lines/strip occur aat the screen while a process happening in the screen. If you have same problem i highly recommed to power of the screen because this lines are occur because of high voltage.
Arduino’s output high level is 5 volts and screen’s high volt is 3.3 volt but tolerated to 5 volts. I used 330 ohms and 1K ohms resisters as a voltage divider for all outputs of arduino. Divided (reduced) voltage goes to the screen. After this correnction , screen works fine.
