## Arduino Wave Player PWM - Super Lite -  Nim

---



* #### Description

    * This project is very simple wave player program with SD card using Nim language and

      using only passive parts, capacitor,diode and resistor except SC card.

* #### Prerequisite

    * [nim-1.6.0](https://nim-lang.org/install.html)  

        * **Important**:  It must be used above nim version otherwise it won't work well.

    * avr-gcc v7.3.0 (inclued in [arduino-1.8.16 IDE](https://www.arduino.cc/en/software))  

        * For example, if on Windows10 set executable path to  

             **d:\arduino-1.8.16\hardware\tools\avr\bin**  

    * make,rm and etc Linux tool commands

* #### Target Boards

    * Arduino Uno / Nano

* #### Schematic and Photo

    [Schematic](#schematic)  

    [Photo](#photo)   

    [Output filter](#output-filter)

* ### Build project

    * You can use make command for build management as follows,

        ```sh

        $ make # build target

        $ make clean # clean target

        $ make w # upload to flash

        ```

        or

        ```sh

        $ nim make # build target

        $ nim clean # clean target

        $ nim w # upload to flash

        ```

    * Artifacts (`*`.hex,`*`.lst files etc) would be generate to **.BUILD** folder.

* #### Supported SD card

    * SDSC/SDHC card  FAT16 and FAT32  

        1. First, format SD card using [SD Card Formatter](https://www.sdcard.org/downloads/formatter_4/index.html)

        1.  Copy PCM wav files to root directory of the SD card.

* #### Supported file

    PCM wave files that have file extension "**.wav**" on root directory.  

    PCM:16bit/8bit, fs(sampling rate)=32kHz,**44.1kHz**,48kHz.  

    Stereo/Mono.    

    

* #### Hardware setting    

    * Refer to the file **./port_setting.txt**     

    * PWM output port:    

        ```

        Audio Left     PWM out : OC1A: PB1, 15pin, D9

        Audio Right    PWM out : OC1B: PB2, 16pin, D10

        ```

    

* #### User button (S1) 

    * D2 (PD2)   Button SW

        * **Next song** : One click during Play mode.    

        * **Play Pause**: Push long time .     

        * **Play**      : One click from Pause state.    

* #### Control from UART 

    * Set baudrate: 38400bps

        * **Next song**:

            Send from key board '**n**' or ' '(**Space**) during Play or Pause mode.    

        * **Play/Pause**:

            Send from key board '**s**' or '**p**' or '**ESC**'(Escape char) during Play or Pause mode.     

            Play or Pause mode would be toggled. 

* #### Display music filename during play mode by UART output.

    * This is debug purpose so only display **8.3 type** filename (ansi).

        - UART output

            ```

            OURPLACE.WAV   # Power on. Start playing music.

            RAINBOWS.WAV

            ACOUST~1.WAV

            ARTP7   .WAV

            HOTELC  .WAV

            OURPLACE.WAV   # Repeat form first file. 

            RAINBOWS.WAV

            ...

            ```

* ### Schematic  

    * Arduino Nano    

        * External 3.3V power is required so that the current consumption of SD card might exceed instantaneously over 100mA when power becomes on.
