Introduction to PEX - the Pokitto EXtension header Pokitto EXtension header (PEX) provides a way to extend the functionality of Pokitto. The header uses a common 0.1 inch pitch - you can connect many electronic components to Pokitto simply by wiring them directly to the PEX. For example, you coul... ...Read more >>

What is “hardware debugging”? “Debugging” means getting rid of “bugs” - program errors. The main idea of debugging is that by using a program called a “debugger” you can stop the running of the program and look closely at what is happening in the code. It makes finding errors a lot easier. Hardwa... ...Read more >>

Troubleshooting Something not working? Make sure your Pokitto’s battery is charged. Some cards can be picky about voltage. Still not working? Try another card. FAT is brittle. Available APIs There are three ways to access the SD card from your code. Each has its pros and cons: - PokittoDisk Based... ...Read more >>
What is it? TAS, or Tiles-And-Sprites, Mode is a screen mode optimized for rendering tilemaps with sprites on top. It uses very little memory compared to modes based on a framebuffer and supports up to 256 colors at either low or high resolution. 2 Specs Resolution: 220x176 or 110x88 Colors: 256 ... ...Read more >>
Programming a Pokitto without pressing any buttons Did you know Pokitto can be programmed using a USB to Serial converter also? This sort of programming is called Serial ISP or UART ISP (ISP = In-System Programming) and it is supported by default by the Pokitto’s LPC11U68 chip ROM. Serial program... ...Read more >>

Introduction: Now that you’ve got your head around digital signals, it’s time to move on to analogue signals. Whereas digital signals represent the values of 1 and 0 using high and low input voltages, analogue signals represent a continuous range of values by varying the input voltage. In other w... ...Read more >>

Using PokittoDisk for Saving and Loading Games that reset highscore every time you restart your Pokitto are good and all, but what if you want a persistent highscore on your game? The PokittoDisk library can do this and much more by allowing the program to interact with files on the SD card. File... ...Read more >>

Introduction: Now that you have learnt how to use the PEX to send a signal, the next logical step is to know how to use the PEX to receive a signal. So for this tutorial I will be showing you how to connect extra buttons to your Pokitto. Components: For this project you will need… 1 Pokitto 1 Bre... ...Read more >>
Introduction The PEX header exposes three of the four pins of USART0. Those can be used to communicate with other serial devices, most notably including another Pokitto for building 2-player games. Very little setup is required for this, either in hardware or software. Components The simplest tes... ...Read more >>
Introduction: When learning programming it is customary to write a ‘hello world’ program - a simple demonstration of how to output text. For electronics I think it is appropriate to use a similar approach of doing something with a simple output, hence this tutorial will show you something very si... ...Read more >>
What is the PEX? The Pokitto Extension Header, or PEX for short, is a way for the Pokitto to interact with electronic devices and circuits. It is essentially a cluster of tiny sockets that can have wires ‘plugged in’ to it to give the Pokitto paths to send or receive electronic signals. The PEX i... ...Read more >>
It is easier to develop Python scripts first on Pokitto Simulator, as the development and testing cycle is faster on PC. An exception is the case when there are features the Simulator do not support, like GIOP-port usage. Also, simulator has a lot of memory and CPU power which makes it to behave ... ...Read more >>
MicroPython is an open source subset of the Python (v. 3) language. Python is an easy to learn, interpreted, and object oriented programming language. MicroPython does not contain all the Python libraries, because of the memory and performance restrictions of embedded systems. MicroPython has bee... ...Read more >>
