I am aware that I am checking in that area, but that is set for where the button is… changing those values, even to 1 didn’t change anything, still thinks I clicked the button regardless of where I press on the screen.
I am unsure how to print the coordinates to the serial monitor, I tried a few different things and couldn’t figure it out. The screen shouldn’t need to be calibrated, as it works fine with the examples. TFT_BL_ON // turn on the background light TouchScreen ts = TouchScreen(XP, YP, XM, YM)
I have tried googling and searching for a couple days now, but obviously have missed something, can somebody explain what is wrong in my code that makes the entire screen a button, instead of just the button area? The code I have below is an example I was working on trying to see if I could get it to work… and it does, sort of…Įverything works display wise, the screen fills, my rectangle and text shows up… and it loads the “settings” page just fine, but it will do it no matter where I press on the screen, even outside the button area.

All examples in the library are written for hardware SPI use. If you plan on using the SD card on the TFT module, you must use hardware SPI. There is no difference in the functionality of the screen between the two methods, but using hardware SPI is significantly faster. The other is to declare all the pins manually. One is to use an Arduino's hardware SPI interface. The screen can be configured for use in two ways. The TFT library relies on the SPI library for communication with the screen and SD card, and needs to be included in all sketches. Onboard the screen is a SD card slot, which can be used through the SD library. The Arduino specific additions were designed to work as similarly to the Processing API as possible. The GFX library is responsible for the drawing routines, while the ST7735 library is specific to the screen on the Arduino TFT. The Arduino TFT library extends the Adafruit GFX, and Adafruit ST7735 libraries that it is based on. Similarly to the screen, the camera module is not 5V tolerant. Make a voltage divider from the Arduino pin 3 to the XCLK pin of the camera. It simplifies the process for drawing shapes, lines, images, and text to the screen. In this chapter, we are going to make all the necessary connections to get the camera running and configured by the Arduino. This library enables an Arduino board to communicate with the Arduino TFT LCD screen. The TFT library is included with Arduino IDE 1.0.5 and later ?.
