![]() The node-usb library makes it possible for us to detect when boards are plugged in and helps us to identify compatible boards. With TypeScript we're able to build a robust and maintainable application in JavaScript. ![]() Socket.IO is a key building block for most of the blokdots integrations, allowing us to exchange messages with a wide variety of other software. The Serialport library makes it possible to talk to devices through serial communcation (now often called UART) from Node.js and is a key building block for Firmata.js and Johnny Five. Redux helps us with state management across the application, making it easier to build a robust application with a good user experience. React Scripts Ĭreate React App provides an out-of-the-box development setup for React with a lot of convenience features. The React framework helps us to write maintainable and relatively performant frontend code for the blokdots UI. In the case of the OLED display we're relying on noopkat's oled-js library to make it work and maintain a fork here React ![]() Some of the supported hardware is fairly complex to handle. The UIPEthernet-library can be downloaded. Many of the hardware components we support are already part of the Johnny Five library and we've also added support for a few new components which can be found at OLED-JS To configure Network Firmata to use an ENC28J60 based board include UIPEthernet.h (no SPI.h required). Thanks to Johnny Five accessing hardware components and creating event-based programs to control the electronics connected to your board is fairly straight-forward. We use the Firmata for Arduino implementation for the firmware and the Firmata.js implementation as part of Johnny Five in the application. Firmata įirmata is the communication protocol used between the microcontroller board and the blokdots application. Electron Įlectron.js makes it possible for us to develop and ship blokdots as a cross-platform application with a tiny team. The Arduino CLI bundled with blokdots is the compiled binary with no modifications from our side.īefore 1.1.0 blokdots was using noopkat's avrgirl library to flash firmware which was a great starting point to improve the user experience of handling hardware prototyping boards. We use the Arduino IDE to compile the firmware for the microcontrollers on your prototyping boards and we use the Arduino CLI to copy the firmware binaries to the board. Arduino CLI Īs of version 1.1.0 blokdots contains a bundled copy of the Arduino CLI for your operating system. Without these projects, blokdots would not be possible. FirmataExpress - Arduino Reference Reference > Libraries > Firmataexpress FirmataExpress Device Control An enhanced version of StandardFirmata version 2.5.8 FirmataExpress utilizes a serial baudrate of 115200. ![]() We want to thank everyone involved and we hope we will be able to give back more in the future. Here is a list of the key open source projects blokdots depends on, which have their own dependencies in turn. In some cases we work with a fork of open source projects which are then public and open source as well. ![]() So although we made the decision to develop the blokdots application as closed source, opting for a commercial business model as a way to fund it's future development, we know that blokdots wouldn't be possible without the open source projects at its core and we try our best to be respectful citizens in the open source ecosystem.įor us that means reporting issues we encounter and creating pull requests with fixes or new features. Without projects like Arduino it's unlikely we would have gotten into working with electronics at all. if (Firmata.SYSEX_RESPONSE) is not an available SYSEX_RESPONSE byte) įirmata.SYSEX_RESPONSE = board => handler.call(board, (2, -1)) įirmata.js is the file from with this modification.Blokdots is truly standing on the shoulders of giants when it comes to open source projects. For iterative use of sysexResponse function (for instance, inside a setInverval block), the exception test-block must be removed (or commented): The file /testesp32/testesp32.ino is a light version for board uploading. Another modification is in /src/utility/Boards.h, which includes esp-32 arch definitions (ongoing update work to increase analog inputs) The library ConfigurableFirmata includes 04 (four) cases to handle each IO sysex command (digital input, digital output, analog input, pwm output). A clean firmata with sysex IO commands for ESP-32 boards ![]()
