St7735 datasheet

The Screen The screen I chose is shown below, finding one very similar will probably make your build easier, but as long as your screen is an SPI screen using the ST driver chip then you should be good to go.

Adafruit ST7735 Color TFT Display Library

As can be seen from the connections it accepts both 5V and 3. This particular one was ordered from Ali-Express and had a picture of a cartoon boy on the screen. I suspect buying any with the same pin connections will give you the same screen as the one above.

But for the price point I wanted this proved impossible. Due to the planned game being more advanced than Space Invaders I needed a processor with more memory and speed than the Arduino could offer.

Enter the ESP processors which offer faster speeds and lots and lots more memory. However they proved to have too few input pins to make controlling the game feasible. So its big brother, the ESP32 was the obvious choice, it has more power than the ESP not that that was an issue and more importantly it has loads of input pins, cool! Wifi is also available but will not be required for this project unless we implemented a World High Score Table perhaps!

It also adds a USB controller chip to handle program transfers with the host computer. Connections — very careful now! So it began to become apparent that this screen had an SPI interface.

Reading several resources for other different screens and looking at the source code for the examples in the Arduino IDE Examples library lead me to find the correct connections to power and use this screen. So I soldered up a header to this side. Made all the connections required…. I then spent some time trying to figure it out.

I eventually just gave up and connected everything up to the 5v side and…. It worked!! Power is self explanatory.

This controls whether we are sending a command to the ST chip or actual data. These last two can connect to any NodeMCU pins that are not used for other functions.

If this is pulled low then this device can receive or send data on the SPI bus. If only one device in your design you could pull this low permanently and not use GPIO5. Driver Code When presented with this board as mentioned above it was difficult to work out where wires should go and what driver software I needed for the display. Looking at the solitary chip on the board and Googling revealed nothing.

Googling this revealed Adafruit had written some drivers for this chip for a board they had created which also had an SD card slot on it as well. It was being armed with this source code and other web pages dealing with different chip sets but similar displays that I managed to work out with a little trial and error the connections talked about previously above.

Initially I used the Adafruit driver code but gave issues with this screen as it was designed to work with the one they sell. Look below. Text clipped off at top, missing quite a bit of start of text.Modules include a MCU, connectivity and onboard memory, making them ideal for designing IoT products for mass production.

The library is working, but still has some bugs I want to get rid off before publishing. I found the bug. The matter was a simple one: I forgot to write the high 8 bits of the pixel. This was due to me thinking that spi. After failing to get a pixel on screen by brute force, I decided to do something more elegant. So, below you can see what putting one pixel on screen black pixel at 1,1 looks like in the nude! Beautiful isn't it!

Useful bit of information! But graphics functions are not working, need to crosscheck the ST and HX, they seem to be different in this respect. You have to lower the clockspeed if you use my functions.

Start with the pixel int x, int y, int colour function. If you get can set a pixel with a colour you have half the way. Thanks for the advice. I started writing this library by looking at Adafruit's library for Arduino. I guess I'll have to look at the datasheet a bit closer as well. The library is now published. I don't have time to figure out the problems with the read functions. So instead I'm publishing this in a not completely ready state, in case someone is interested in looking at it.

Jonne, I'm trying to get your library up and going, and it's not working for me. The demo works perfectly, but if I import the library into a new program it fails to compile.

I get the error: no instance of contructor "mbed::Stream::Stream" matches the argument list. Any ideas? Hi Tanner. I haven't used my mbed for a while now, so I might get this wrong. I'll dig mine out if you can't get your problem solved.

But in any case: off the top of my head, Stream is a class defined in the core mbed libraries - not in my library. Try to include the other libraries that are included in the main. How do yo implement your demo animation? Well, It's great, your library really working!!

But I have the first two lines and the first column of the screen uninitialized after running myTFT. I don't find the mistake. Please log in to post comments. ST SPI 1. It has an ST graphics controlle on board. I'm wiring it up to the mbed and modify some libraries to do it.JavaScript seems to be disabled in your browser.

To complement the display, it also comes with an SD card slot on which colored bitmaps can be loaded and easily displayed on the screen. The goal of this tutorial is to demonstrate the abilities of the TFT to display images and text in different colors and some animation.

As usual, the exact components used for this tutorial can be bought by following the link attached to each of the components above. The schematics for this project is fairly easy as the only thing we will be connecting to the Arduino is the display.

Connect the display to the Arduino as shown in the schematics below. Due to variation in display pin out from different manufacturers and for clarity, the pin connection between the Arduino and the TFT display is mapped out below:. Double check the connection to be sure everything is as it should be. All good?

We will use two libraries from Adafruit to help us easily communicate with the LCD. This example displays the analog value of pin A0 on the display.

It is one of the easiest examples that can be used to demonstrate the ability of this display. The second example is the graphics test example from the more capable and heavier Adafruit ST Arduino library. The first thing, as usual, is to include the libraries to be used after which we declare the pins on the Arduino to which our LCD pins are connected to. We also make a slight change to the code setting reset pin as pin 8 and DC pin as pin 9 to match our schematics.

Next, we create an object of the library with the pins to which the LCD is connected on the Arduino as parameters. There are two options for this, feel free to choose the most preferred.

Next, we move to the void setup function where we initialize the screen and call different test functions to display certain texts or image. This functions can be edited to display what you want based on your project needs. Next, is the void loop function. The void loop function for this project basically inverts the display after ms. All the functions called under the void setup function, perform different functions, some draw lines, some, boxes and text with different font, color and size and they can all be edited to do what your project needs.

The complete code for this is available under the libraries example on the Arduino IDE. Uploading the code to the Arduino board brings a flash of different shapes and text with different colors on the display. I captured one and its shown in the image below. Feel free to reach me via the comment section if you have any questions as regards this project.

Ssor Thanks to you for sharing this valuable article 2 years ago. Wally Anglesea Wanglese. Thats the lamest answer EVER!!! Leave a Reply Cancel reply. Using the 1.And to see how to interface Arduino with BME sensor for the first time, take a look at this post: Arduino with BME pressure, temperature and humidity sensor.

Arduino weather station circuit: The image below shows project circuit diagram. Hint: The BME chip works with maximum voltage of 3. This level shifter is for the I2C bus lines clock and data. The BME module shown in project circuit diagram has a built-in 3.

Normally the ST display works with 3. This regulator supplies the display controller with 3. To avoid that, I connected each control line of the display to the Arduino board through 1k ohm resistor. ZIP Library … and browse for the. The same thing for the other library files. In the code, the definition of BME sensor I2C slave address and the initialization of its library are as shown below:.

The initialization of the BME sensor is done using the function begin which returns 1 if OK and 0 if error. In the code the initialization with the previously defined address is as shown below:.
