Si4735/Si4732: TEmbedFMRadio sketch from Volos Projects ported to the Si473x.

This Si473x Radio uses the amazing library written by PU2CLR/Ricardo Caratti. It is based on sketch from Volos Projects. @VolosProjects YouTube channel has a lot of tips and tricks for Lilygo T-Embed and Lilygo T-Display. I recommend this YouTube channel if you want to know more about this device and also about the tft_espi library, especially how to use sprites. I am using a Lilygo T-Display S3, which is an ESP32S3 board with a 1.9 inch display with a 8-Bit Parallel Interface, but I believe it will also run on Lilygo T-Embed by commentting out the line “#define I_use_T_Display_S3. If you want just to look and feel the interface, it’s also possible to run this sketch without Si473x. To do this, uncomment de line “#define SI4735_EMUL“ For now, my sketch only runs FM with RDS. On reset, all settings will return to default. * Ralph Xavier Github: * Si4735 Library: * Volos Projects Github: h
