Radio station no wifi

KaRadio32 интернет-радио. Делаем сами и все получится.

После прочтения статьи KaRadio + Smalody = Love загорелся желанием сделать нечто похожее. KaraWin — автор проекта интернет-радио KaRadio32 . Очень подробная видеоинформация об этом радио на канале Konstantin Pavljuchenko в YouTube и здесь: WI-FI интернет радио DIY . Вроде все просто и понятно, но как оказалось, не совсем. Пришлось разбираться. В итоге интернет-радио «заработало». На самом деле радио работало, но не так как я ожидал. Ссылка на рабочие файлы для повторения описанного ниже интернет-радиоприемника, использующего модуль ESP32-WROVER в самом конце статьи.

Мое повторение конструкции не задалось. В чем оказался подвох? Оказалось — все просто, как обычно. Во — первых, в файле конфигурации от автора выявилась ошибка — у двух энкодеров оказались общие выводы модуля ESP32. В результате энкодер якобы оказался не работоспособным. Во-вторых, я сконфигурировал KaRadio32 на отключение дисплея через 5 с при бездействии KaRadio32. Поэтому отсутствие информации на дисплее радио в основном режиме работы я воспринял как неисправность. В- третьих — в плейлист радио я умудрился внести единственную не работающую радиостанцию. Ну и самое главное — при программировании модуля ESP32 я не удерживал нажатой кнопку BOOT. И еще. при изменении файла конфигурации нужно быть очень внимательным.

Сразу оговорюсь, проект реализован в виде рабочего макета на модуле ESP32-WROOWER-B , имеющего программную память размером 4 Мб . Как показала практика, возможно использовать также модуль ESP32-WROWER-E, у которого программная память составляет 16 Мб — но целесообразность такого использования сомнительна. Процесс изготовления был интересен и познавателен. В результате появилась конструкция WEB-радио с поддержкой битрейта до 320 кбит/с, поддержкой инфракрасного приемника (протокол NEC), цифрового аудио-интерфейса I2S, OLED дисплея I2C 1,3 дюйма, UART TTL, светодиода и различных органов управления: двух экнодеров с кнопкой и отдельной группой кнопок в количестве 3 шт. Группа 0 энкодера и кнопок имеет приоритет по громкости. Соответственно группа 1 — по перебору станций из загруженного в радио плей-листа. В предложенной конфигурации возможно использовать аналоговый выход аудио (декодирует ESP32) с посредственным качеством (не используется — отсутствует разьем для подключения ). Количество свободных выводов модуля ESP32 определяет конфигурацию настраиваемой периферии для управления WEB-радио. Для переназначения выводов ESP32 нужно изменить файл конфигурации, определив выводы для кнопок, энкодеров, IR приемника, светодиода. Подробнее здесь .

Далее распишу и прокомментирую что и как делать. Главное что нужно понимать — основная конфигурация исходной схемы, предложенной автором KaRadio32, не изменяется.

Итак, для реализации проекта интернет-радио KaRadio32 потребуются четыре части: программная, аппаратная, реализация и программирование.

Схема электрическая принципиальная от автора интернет-радио KaRadio32 для модуля ESP32-WROOM представлена ниже и в дальнейшем, в части интерфейсов, не изменяется. Обращаем внимание только на нумерацию логических выводов типа IOxx, где xx — это номер, который будем использовать в файле конфигурации. У модулей WROOM и WROVER физические выводы не совпадают.

The Best Offline No-WiFi Radio Apps for your Phone [August 2020]

If you own an Android phone, there’s a good chance you might be missing out on one of the coolest features around—a built-in portable FM radio. Although not every Android phone includes an FM radio by default, many do, both in the US and around the world. FM radios are typically included in case of emergency, but it also allows customers to stream music without using data. At first glance, you would think that listening to radio without a network connection on your phone wasn’t possible. After all, if you don’t have data, you don’t have streaming. Thankfully, many phones—primarily Android phones, since Apple no longer includes FM radios in their devices, and even older phones didn’t allow you to use them—are capable of reaching out to FM stations near you.

The downside of trying to listen to radio without data is that not all networks enable the FM chip within their phones. There’s no good way to see if your phone supports FM radio transmissions without just testing an app, but thankfully, our top pick lets you do just that. Here’s our favorite radio apps that, some of which, unfortunately, do require WiFi to use.

NextRadio

Android

The easiest way to find out whether or not your phone is able to receive FM radio broadcasts without relying on streaming over the web is to download NextRadio, a fantastic and free radio app for your phone. As with all FM radio apps, NextRadio will require earbuds to properly receive a broadcast signal, and the app won’t work if your phone doesn’t have the necessary hardware to pick up. If you do, all you’ll need is a stereo cable or a headphone cable to act as an antenna, and you’ll be able to stream from any of your surrounding FM radios, live and for free.

The app itself features a solid design, though it’s a bit dated compared to some of the newer apps that have rolled out on Android in the last few years. Thankfully, the most important tool—being able to quickly sort through channels—works wonders here, so you won’t have to worry about being unable to find your favorite rock or pop station within the app.

If there’s one reason to switch away from NextRadio, it’s actually that the app is no longer in active development. NextRadio was originally designed to work as both an FM receiver app and as an online streaming service, but at the start of 2019, the app switched back to only offering FM radio and hasn’t been updated since. The service’s website has also gone offline, so if the app doesn’t work with your specific phone, it likely never will.

Still, it’s one of the better reviving apps you’ll find today, and it remains our top pick for that very reason.
