TEST TONE GENERATOR V4.4 CODE CODE
Visual Studio Code version 1.43.1 with the Arduino extension was used for development. As a consequence, all image data is defined inline and only the CSS file is served separately from the HTML. The number of static files has been reduced to its practical minimum due to limitations of the webserver. The front-end is built using Materialize. Amplitude : Sets the amplitude to a fraction of the maximum (5V).Phase °: Sets the phase offset (in °).The DAC can still produce a signal above the maximum frequency, but it will become progressively distorted. The minimum and maximum frequency depend on the selected clock divider (min = 135/(clk_div + 1) max ≈ 135k/(clk_div + 1)). Frequency Hz: Sets the frequency of the selected channel (in Hz).Invert : Sets the inversion mode of the selected channel (MSB for non-inverted sine waves).Clock divider : Selects the divider for the selected channel from the DAC clock, which runs at 135Hz.The ESP32 has two DAC channels (1 and 2) connected to GPIO pins 25 and 26, respectively. The maximum frequency depends on the selected resolution. Frequency Hz: Sets the frequency of the selected timer (in Hz).Highspeed : Defines whether the selected timer runs in highspeed mode.Resolution bit: Sets the resolution of the selected timer (in bits).Output GPIO Pin : Selects the GPIO pin used to output the configured signal for the selected channel.

TEST TONE GENERATOR V4.4 CODE SOFTWARE
The software is configured to connect to a WiFi network after booting, for which the configuration is stored in the ♜'s EEPROM.

Since the static files of the website are being served from a simple on-device filesystem, it is necessary to format the flash storage once prior to first use: To upload the static web files to the device, ESP32 Filesystem Uploader was used. The Arduino software version 1.8.15 with the esp32 board extension version 1.0.6 was used for building and uploading. The ESP32 DevKitC V4 was used for development and testing. Configuration of the signal generator is done using a web-based UI, which is served directly from the device via WiFi.
