ESP32-ADF based SIP Phone looks really cool with LittlevGL

esp32-adf-sip1

We blogged a while ago about one of the demo code we work on for ESP32-ADF – SIP IP phone. Our vacation delay a bit this project, but now it’s almost ready and we want to share some details.

We used LittlevGL framework for the UI. You can see on the picture above how the phone app looks on the LCD.

LittlevGL required some touching as default didn’t work well with the touch screen, but we managed to add support, the touch panel recognize gestures like slide, tap etc.

We need few more days to finish dialing sounds etc details and will upload on GitHub our patches for LittlevGL and our SIP IP phone demo.

We are so impressed with the result that we may release soon all in one LCD+ESP32-ADF and camera so we enhance the phone with camera and open more applications like Home automation WiFi Door-Phone, security panel with sound and video and other apps based on this configuration.

Some demo codes for ESP32-ADF are now uploaded on the GitHub.

Google Assistant demo will allow you to build your very own Google Assistant speaker, display and to integrate these services in your future product.

Internet Radio is preliminary and we still work on the UI to be uploaded later this week.

Amazon Alexa is the GA competitor and you can embed it with your Home assistant and automate your home.

Google Dialogflow is easy way to use Google AI in your products and make them voice controllable. It builds voice to text service and you will receive plain text delivered from the voice the device listen to. This way you can add voice control to every of your products. All you need is internet connection.

The SIP phone demo is also to be uploaded later this week.
