In the previous post, ESP8266 was playing music based on pitch sequences and a recording of a sine wave. This is not sufficient for the speech sythesis system. A method for playing WAV files is required.
Fortunately, WAV format uses PCM to represents the waveform. Thus the data can be …

One of the projects I am currently working on is a text to speech system based on ESP8266 (or more realistically - ESP32). It will utilize the CMU Flite speech synthesis library. But a way to play back the synthesized waveform is also required.
For this propose, I will use a …

In 2016 I wrote a tutorial about connecting ESP8266 with an ili9341 TFT display. That tutorial suggested using Adafruit's library modified to work with the ESP8266.
Now I discovered that there is a much better library which is tailored for the ESP8266. This library is called TFT_eSPI.
This library is …

I will write about Arduino, but this technique is relevant for any embedded situation.
Many applications require retaining data such settings or parameters between resets. On the Arduino, the already existing EEPROM of the Atmega chip is a common solution for this problem.
For the Arduino, the EEPROM library can …

ESP8266 was popular with hobbyists for a long time. Recently I decided to join the hype and bought this module along with a super cheap color TFT display (ILI9341). In this post I will describe the process of connecting those two, using already available code written for Arduino.
First step …
