Пытаюсь подключить Grove MP3 V3 к Ардуино леонардо. Беру код с официального сайта производителя, ничего не работает. Но один аудиофайл воспроизводится при нажатии кнопки перезапуска на плеере, он работает. Библиотеки подключены. Плата и порт выбраны.

SoftwareSerial Library
The Arduino hardware has built-in support for serial communication on pins 0 and 1 (which also goes to the computer via the USB connection). The native serial support happens via a piece of hardware (built into the chip) called a UART. This hardware allows the Atmega chip to receive serial communication even while working on other tasks, as long as there room in the 64 byte serial buffer.
The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality (hence the name "SoftwareSerial"). It is possible to have multiple software serial ports with speeds up to 115200 bps. A parameter enables inverted signaling for devices which require that protocol.
The version of SoftwareSerial included in 1.0 and later is based on the NewSoftSerial library by Mikal Hart.
To use this library
#include <SoftwareSerial.h>Limitations
The library has the following known limitations:
If your project requires simultaneous data flows, see Paul Stoffregen's AltSoftSerial library. AltSoftSerial overcomes a number of other issues with the core SoftwareSerial, but has it's own limitations. Refer to the AltSoftSerial site for more information.
1. Код вставить по правилам не смог.
2. На Леонардо есть хард сериал (ысчо адын). Нахера софтварный???
3. Выше привел кусок документации - ТАК КАК ТЫ НАПИСАЛ -- НЕЛЬЗЯ!
====================
Вывод: долбо..б. Фтопку!
rx воткнуть в 8? А с кодом че?
