![]() ![]() This project based on ATMEGA32L MCU, that may operate on 3.3V and a frequency of 8MHz. The purpose of the MCU is to manage all the peripheral systems, handle communication between these systems, controlling hardware operation and providing complete support for user interface and its interaction with an actual user. In our case, it is the "brain" and a central component of the system. Microcontroller is a programmable chip that consists of all the computer functionality that resides in a single electronic chip. Buzzer circuit - sound feedback to user. ![]() Android application - complete user control over the FuncGen device.20 x 4 Character LCD with simple 4-bit data interface.State monitoring - both systems are aware of each other state: FuncGen (let's call it this way from now on) and smartphone.Ability to store user parameters for every device cycle.Complete TCP/IP support by generator device and Android smartphone.Implementation of ESP32 - Applicable WiFi capabilities.Separated channels for waveform generation - split AD9834 based circuits.Output current up to 80mA with 500mW maximum power availability.DDS based 4-type waveform generation - Sine, triangle, square and DC.Implementation of DC level at the output cascade - biased waveform between the voltage boundaries.Dual power supply: +3.3V and -3.3V for symmetrical voltage waveform generation.Smart Switch implementation - no need for power toggling switch.Complete Li-Ion battery management system - Charging and stable modes.USB Type-A connector, for both power supply systems and programming.As a solution for high prices, lack of portability and lack of device network access, device provides dual channel waveform generator, that is indeed portable and has an unrestricted access to the network - either internet or local one.Īnd of course, device should be built because of enthusiasm, obeying the DIY principles - Sometimes we just have to do things ourselves in order to feel right :) Key Features ![]() And sometimes, these devices aren't portable. Why should we build this device?Ī vast majority of testing equipment is pretty much expensive nowadays. Since everything can be "smart" nowadays, I've decided to design a super-useful device to be the part of essential electronic lab equipment - Portable Function Generator, controllable by Android OS based smartphone via WiFi direct or WiFi Local Area Network (WLAN). For us, users, consumers and engineers came to light rapid developing of electronic devices, that can make our lives a lot easier: Smart watches, smart homes, smartphones etc. GmbH, the support doesn’t always respond in english or promptly.Near the end of 20th century, various technological innovations popped up, especially in the field of communications but not only. Although you can contact the support of EUMLab of Xanin Tech. InsTuner – Chromatic Tuner with Tone Generator Report a crashĭo you know any other solutions if insTuner – Chromatic Tuner with Tone Generator keeps crashing? Then you can help others or report problems yourself.
