Oryx Signal Studio is a **signal editor**. You draw a signal step by step —digital or analog—, read it, interpret it as a serial protocol frame and then take it out: to a file, or straight to an **ESP32 generator** over USB. It is not an oscilloscope or a circuit simulator. It is the piece that comes before: the tool where you *define* the waveform you are going to generate, measure or compare later. ## What you can do A grid of steps per channel. Every cell is high or low, and a step can be split into sub-steps to write frames bit by bit. Points pinned to the dividers and chords between them, stretched and rounded until you get the curve. UART, CAN, I2C and Modbus. The frame reading shows up under the channel, field by field, with the errors marked. The signal travels to the device over USB, and you start, stop and tune it from the app. A `.txt` you can read yourself and your microcontroller can read too. 60-2, 36-2, 36-1 or custom tone wheels, with the camshaft pulse synchronized by angle. ## Two modes You work in **digital mode** or **analog mode**. They are separate projects: each one keeps its own channels, signal and history, and switching modes leaves the other one alone. See [Signal modes](/en/concepts/modes). ## Before you start The app is meant for computers. Below **1280×720** an overlay asks you to open it on a PC or enlarge the window; whatever you already drew is not lost. To connect the ESP32 generator you need **Chrome, Edge, Opera or Firefox**. Safari cannot talk to the USB port. Any browser works for drawing and exporting. ## Where to go next From the welcome screen to your first signal. What this is used for in practice.
