After using the AI Thinker AudioKit I wanted to make sure that my libraries also work with the ESP32 LyraT Board from Espressif. There were basically just 2 stumbling blocks: Deploying Code: From the AudioKit I was used that I can plug in the UART cable and upload the code Read more…
I decided to use my SAM TTS Library with the AI Thinker Audio Kit. Unfortunately I found quite some bugs in my library that I needed to correct first, but now it is working as expected. Here is the Arduino Sketch #include “sam_arduino.h” #include “AudioTools.h” #include “AudioLibs/AudioKit.h” AudioKitStream kit; SAM Read more…
My Arduino MIDI Library is using Arduino Streams as a basic design feature and therefore it supports Bluetooth, TCP/IP and UDP. I am usually programming on an old Macbook, so I was wondering if I can extend my library to support Apple MIDI as well. After some research I found Read more…
In one of my previous posts I gave an overview on how we can connect a microcontroller to a MIDI Device using a physical serial connection with the help of my Arduino MIDI Library. This solution is very similar, but replaces the physical connection with Serial Bluetooth This solution will Read more…
In one of my previous posts I gave an overview on how we can connect an microcontroller to a MIDI Device. The simplest solution is to connect the MIDI Keyboard to the PC and use a FTDI serial adapter to communicate with your microcontroller. Because the keyboard is only sending Read more…
In this Blog I would like to look into the options how we can connect a microcontroller with a Midi Keyboard. MIDI is a communication protocol from the 1980s that connects musical instruments and computers. MIDI keyboards nowadays usually have USB support and offer a separate MIDI port. Some modern Read more…
As you might know from my last posts I am currently extending my Arduino Audio Tools library to support the AI Thinker Audio Kit which is based on the ES8388 audio chip. I didn’t do much with my Arduino STK project lately, so I think this is the perfect opportunity Read more…
In the last Blog, I have shown how to use the Synthesizer class. I wanted to verify the audio quality issue by sending the output to Bluetooth Here is the sketch. I just added a callback method to feed the bluetooth source: Arduino Sketch #define USE_MIDI #include “BluetoothA2DPSource.h” #include “AudioTools.h” Read more…
I have described in my last blog how to build a simple Synthesizer with my Arduino Audio Tools library to support the AI Thinker Audio Kit which is based on the ES8388 audio chip. In the meantime I have decided to wrap the described solution into it’s own Synthesizer class Read more…
As you might know from my last posts I am currently extending my Arduino Audio Tools library to support the AI Thinker Audio Kit which is based on the ES8388 audio chip. In my Arduino Audio Tools we have all ingredients to turn our ESP32 AudioKit into a simple synthesizer Read more…
