USING THE 1.44" ST7735 COLOR TFT DISPALY WITH ARDUINO.

hello everyone today I would like to talk about the TFT is t77 through five color display and how it can be connected to the adrenal so in previous tutorials of been showing out use different types of displays for example use the normal LCD 16 by to display I've also talked about the LED display even these seven segment displays but sometimes may need to have some colored feature that you want to display so this kind of this becomes in a bit handy so you sub because I look at it so this is our display here you know there you can see the labels properly okay so from here you can be able to see how about make connections visible this displays usually come in various sizes and sometimes meant even have if you had a pin in Livadia but these are the you know pills that are present in all the this place so in most cases are gone fine you have the same have a grown pin so that is gonna be connected to the ground as video then of the VCC this VCC can be connected to the 5 volts because this display has an onboard regulator because the display is 3.3 volts so you can connect it to the 5 volts of the Adreno did you work however I will recommend using the three point three votes pin out just keep it has the best practice so you have take note of that for the VCC then we have the clock the clock was to pin 13 of Arduino board and then that opinion was too busy living there nothing else isn't about these two pins that you shouldn't change the configuration of the pins this one should be clocked a team and the data pin 11 this because most libraries that have been programmed to run this displays have programmed the clock and data pin to use pin 13 and 11 this correspondingly they offer shouldn't change that condition otherwise the discriminant work then you have the the reset pin you have this disappear and then the chip selects this one's you can choose an addicted pin to connect them and then you have to specify which pins have been contending lis all as I'm gonna be showing there don't have this back-right pin I have on this case you don't really connect it you don't usually need it back right so I'll just leave it there so the maintains big ground this is the clock data reset busy and chip select so from there can have a closed simple loop and the kind of code you're gonna be using for this kind of display so if I can be able to trade our personal code we out fast test whether the display is really working properly and that is done using the example codes from the library that you are going to be installing so you need to first check whether I have that library in our IDE and that is simply good to able to sketches then you go to include library then you go to manage libraries from you can be but actually so the libraries that you have in your IDE and simply just look for the other fruit is t77 305 library so just up here to simplify the work seven seven so this is the library that you want you gotta make sure of this library Adafruit is T 775 an ST seven seven eight nine library so if you haven't installed it make sure it is installed you can install it from the other fruit website I'll put the link in the description for the video so you can check it out so after installing this then you can be able to access the example that you can be used to check out our display and do that you simply go to file then you go to examples and look for the this library at the fruit is T seven seven three five and STS seven seven eight nine library then from here I can be able to check out using any of these examples here I always like using the graphics test example since the one I'm going to choose and then you can see how it is going to display on our screen so this is a graphics test example that you're going to be using and maybe one thing I need to emphasize is that before you can upload your program and it makes some simple changes see one you have to make sure that you specify we are planning to do these pins yeah this is a visit and BC peds sometimes may use different pins also make sure you specify but make sure you don't change the clock and that opinions they have to be on pin 13 and pin 11 of your abrino board that you're using because those ones are programmed within the library so shouldn't india of creation and then the other things are taken off are the different settings for the different sizes of the screens that you are using so you out make sure you often you know the size of the screen that you are using for example using a 1.4 inch LCD display so i'm going to be using this in here so if you're using for example 1.3 inch you uncomment this and then you comment out this and uncomment this so you'll be using this definition and then the other part that you'll confuses is here the initializer here when you initializing for example here in this case originally it is for the 1.8 inch of this screen but in my case I'm using one point four four inch it means this one I'm going to comment it out and then I'll go here and uncomment this so it means this is going to be the initialization for the one point four four inch screen that I'm using so should take care of that so these ones depend on the size of the screen are using so if using the Roper named six inch un-comment this and comment this one or the others or to be commented out so the rest of the code after that you just simply upload it and let me check this how it's going to appear on the screen to see if the screen is working so let's upload this one and we have a look at what we are going to get so we now upload the testing code from graphics or the graphics test code and that's what is showing on the display as per now which is different figures on ships so after here can be able to see that our displays working properly and then you can be able to put our personal code and then even this display this graphics code is going to apprise to give us an idea about the code is supposed to be our end and cause most cases when a gun program just simply make a few changes to the code but you know the most of the code already been written so average another a simple code there is a personal code one says the screen using the basic disc functions so I will just upload this one and see what it's going to also display yeah showing simple rectangle and triangles and like that so let's apply this one angle so see the display which is different figures on ships so after here can be
