Looks like the FabGL has contradictions in their web pages. One page seems to have the order different from the other. I was using the one page to define the pins when I did the above update.

I think the original schematic was actually correct. Switching back. The TerminalCharSet sketch shows this behavior well. When I swapped the resistors the screen got really dim. I am going to switch back the parts on the card to the original order. Some pages say VGA output is 0. This seems to be based on the composite video spec.

ESP32 VGA Tetris

Composite video IIRC has a swing down to Black is 0V. The white level is 0. These are not standard values and don't achieve the possible drive for a VGA monitor.

I ran a simulation and picked the best common resistor values. The best values are and ohms.

The early FabGL schematic had a wrong pin for the serial port. Rev 2 of this PCB will use the pin.

The downside of this is that the Rev 1 card can't download sketches from the Arduino when there is a powered FTDI connection on the port. The card can be removed from the board and programmed just fine. Lines were swapped on the Rev 1 board. This was easy enough to correct on the schematic but could also be fixed by changing the pins used in the Arduino sketch.

Will fix the silkscreen on the Rev 2 board. Adding an SD Card connector on the Rev 2 version of the board.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

You can also support me getting my own development board. This library works with ESP32 revision 1 or upper. See Compatible Boards. VGA output requires a digital to analog converter DAC : it can be done by three Ohm resistors to have 8 colors, or by 6 resistors to have 64 colors.

Unlimited number of sprites are supported. However big sprites and a large amount of them reduces the frame rate and could generate flickering.

When there is enough memory on low resolutions like xit is possible to allocate two screen buffers, so to implement double buffering. In this case primitives are always drawn on the back buffer. Except for double buffering or when explicitly disabled, all drawings are performed on vertical retracing using VGA driverso no flickering is visible. If the queue of primitives to draw is not processed before the vertical retracing ends, then it is interrupted and continued at next retracing.

There is a graphical user interface GUI with overlapping windows and mouse handling and a lot of widgets buttons, editboxes, checkboxes, comboboxes, listboxes, etc. Finally, there is a sound engine, with multiple channels mixed to a mono output. Each channel can generate sine waveforms, square, etc Skip to content.

You can send both textual and voice commands to the board e. The messages are displayed with a timestamp. You can also publish data sent by the device on the app, hence acts as a wireless serial Bluetooth terminal. The terminal module allows you to both send data to the hardware device and receive data from the hardware device.

This module is similar to the serial monitor where you see the data sent and received from the device in real-time. You can display the sent and received data on the terminal in the following formats:. To include the Terminal module in the Arduino program, you have to include the following header:. After defining the above mention headers, you have to include the dabble library:.

With evive, you normally get baud rate HC or HM modules. You can use the terminal in the following three ways. The example given below shows how to carry out a general communication between the Terminal module and your board. Upload the code and open Serial Monitor. Send any data from the Serial Monitor. You will be able to see it on your terminal screen. Similarly, send any data from terminal it will be displayed on Serial Monitor.

Code for all boards is given below. Copy the code as per your board. Mega, Uno, and Nano. Below is the script in Stage mode in Pictoblox. The rest of the script remains the same. This project will show you how to lock and unlock a door using Dabble, a project-making mobile application.

Some of the sketches use it as storage. The pins are on the GVS connector.Since the last version has been published just a couple of weeks ago, it is still work in progress but it already provides some simple examples. Compared to my previous projects where I wrote similar vintage game clones for the Arduino or ESP, the ESP32 is extremely more powerful, the VGA output with various resolutions x, x, x, x and up to 14Bit colors. Furthermore you have orders of magnitude more memory. In this Tetris clone I am just using a resolution of x with 8 colors.

The code is a quick "conversion" of a previous version for the Arduino VGA, thus it is poorly designed and un-optimized. I wish that this project would be of use to other makers to write many other games in the future. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. First of all you need to puchase an ESP There are many versions available, but I recommand to choose one with many pins.

I bought this version, but you can fiund three other versions in the description of this video. If the upload works without any issue, you need to connect the VGA port as shown in the next step.

For Tetris, and the 8 colors library examples, you do not need any resistor, just connect the pins as follow:. I am very grateful to bitlunithe author of the ESP32 VGA library and the tutorials and examples to use and exploit it. Please, visit his site and video to see more details and all its potentiality. Question 1 year ago. MODEx, 14, 27, 16, 17, 25 ; and wemos esp32 board it turn all the time in game over.

I don't arrived to play. By Rob Cai Follow. More by the author:. Add Teacher Note. To play Tetris, you need four buttons and four resistors of about 1 to 2 kOhm. Connect one side of the button to ESP32 3. Upload it on the ESP32 microcontroller and you can immediately start to play Tetris!GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
