# PSoC 6 MCU: USB Mass Storage Logger

This example demonstrates how to configure the USB block in a PSoC® 6 MCU as a Mass Storage (MSC) device and emulate a file system in the SRAM memory.

## Overview

In this project, PSoC 6 MCU USB block is configured for Mass Storage. This allows it to enumerate on the computer as a portable storage device. The firmware emulates a file system using the internal memory with one file, which is visible to the USB host. The content of the file changes every time the user presses the kit button.

To see the Mass Storage descriptor, use the `usbdev-configurator` tool located at *<ModusToolbox_install_dir>/tools_<version>/usbdev-configurator*. In the tool, open the *design.cyusbdev* file located under the */COMPONENT_CUSTOM_DESIGN_MODUS/<target>* folder.

## Requirements

## Hardware Setup

This example uses the board's default configuration. See the kit user guide to ensure that the board is configured correctly.

**Note**: The PSoC 6 BLE Pioneer Kit (CY8CKIT-062-BLE) and the PSoC 6 WiFi-BT Pioneer Kit (CY8CKIT-062-WIFI-BT) ship with KitProg2 installed. ModusToolbox software requires KitProg3. Before using this code example, make sure that the board is upgraded to KitProg3. The tool and instructions are available in the [Firmware Loader](https://github.com/cypresssemiconductorco/Firmware-loader) GitHub repository. If you do not upgrade, you will see an error like "unable to find CMSIS-DAP device" or "KitProg firmware is out of date".

## Software Setup

This example requires no additional software or tools.

## Using the Code Example

### In Eclipse IDE for ModusToolbox:

1. Click the **New Application** link in the Quick Panel (or, use **File** > **New** > **ModusToolbox Application**).

2. Pick a kit supported by the code example from the list shown in the **Project Creator - Choose Board Support Package (BSP)** dialog.

   When you select a supported kit, the example is reconfigured automatically to work with the kit. To work with a different supported kit later, use the **Library Manager** to choose the BSP for the supported kit. You can use the Library Manager to select or update the BSP and firmware libraries used in this application. To access the Library Manager, right-click the application name from the Project Workspace window in the IDE, and select **ModusToolbox** > **Library Manager**. You can also access it from the **Quick Panel**.

   You can also just start the application creation process again and select a different kit.

   If you want to use the application for a kit not listed here, you may need to update the source files. If the kit does not have the required resources, the application may not work.

3. In the **Project Creator - Select Application** dialog, choose the example.

4. Optionally, update the **Application Name:** and **Location** fields with the application name and local path where the application is created.

5. Click **Create** to complete the application creation process.

For more details, see the Eclipse IDE for ModusToolbox User Guide: *{ModusToolbox install directory}/ide_{version}/docs/mt_ide_user_guide.pdf*.

### In Command-line Interface (CLI):

1. Download and unzip this repository onto your local machine, or clone the repository.

2. Open a CLI terminal and navigate to the application folder. On Linux and macOS, you can use any terminal application. On Windows, navigate to the modus-shell directory (*{ModusToolbox install directory}/tools_\<version>/modus-shell*) and run *Cygwin.bat*.

3. Import the required libraries by executing the `make getlibs` command.

### In Third-party IDEs:

1. Follow the instructions from the CLI section to download or clone the repository, and import the libraries using the `make getlibs` command.

2. Export the application to a supported IDE using the `make <ide>` command.

3. Follow the instructions displayed in the terminal to create or import the application as an IDE project.

For more details, see the "Exporting to IDEs" section of the ModusToolbox User Guide: *{ModusToolbox install directory}/ide_{version}/docs/mtb_user_guide.pdf*.

## Operation

1. Connect the board to your PC using the provided USB cable through the KitProg3 USB connector.

2. Program the board.

   - **Using Eclipse IDE for ModusToolbox**:

      1. Select the application project in the Project Explorer.

      2. In the **Quick Panel**, scroll down, and click **\<Application Name> Program (KitProg3)**.

   - **Using CLI**:

     From the terminal, execute the `make program` command to build and program the application using the default toolchain to the default target. You can specify a target and toolchain manually:
      ```
      make program TARGET=<BSP> TOOLCHAIN=<toolchain>
      ```

      Example:
      ```
      make program TARGET=CY8CPROTO-062-4343W TOOLCHAIN=GCC_ARM
      ```

      **Note**:  Before building the application, ensure that the *deps* folder contains the BSP file (*TARGET_xxx.lib*) corresponding to the TARGET. Execute the `make getlibs` command to fetch the BSP contents before building the application.

3. Connect another USB cable (or reuse the same cable to program the kit) to the USB device connector (see the kit user guide for its location).

4. On computer, verify that the OS recognizes a new portable device named *PSoC Logger*. Confirm that a file *LOG.TXT* is readable.

5. Open the *LOG.TXT* file and read the content. It should have the message:
   ```
   PSoC Logger Content:
   ```

6. Close the *LOG.TXT* file and press the kit user button multiple times. Disconnect and reconnect the USB cable to enumerate the device again.

7. Open the *LOG.TXT* file again and check whether new content was added to the file:
   ```
   PSoC Logger Content:
   > Button press 1 time(s)
   > Button press 2 time(s)
   ```
8. Alternatively, you can press the button five times. It will emulate the device being ejected and inserted back, forcing the OS to re-read changes in the mass storage.

## Debugging

You can debug the example to step through the code. In the IDE, use the **\<Application Name> Debug (KitProg3)** configuration in the **Quick Panel**. For more details, see the *Program and Debug* section in the Eclipse IDE for ModusToolbox User Guide: *{ModusToolbox install directory}/ide_{version}/docs/mt_ide_user_guide.pdf*.

## Design and Implementation

In the main firmware routine, the USB Device block is configured to use the MSC Device Class. The firmware also creates a simple FAT file system placed on the internal SRAM. It creates a single file named *LOG.TXT*. The file size is configurable through a macro and the necessary memory is allocated automatically. The USB Host can only read the contents of the file. There is no write support.

Internally, the firmware can write data strings to the file system or erase the entire file content. As an example, the firmware writes a message every time the kit user button is pressed. To read the new file content, you must disconnect and reconnect the USB cable, so that the OS requests again for the content in the file system.

The firmware also emulates the device being ejected at every five user button presses. This forces the OS to re-read the contents of the file system.

The following list shows the files of this code example:
- *config.h*: Configures some global options for the application
- *file_system.h/c*: Implements the FAT file system
- *usb_scsi.h/c*: Implements the USB SCSI protocol, which is used by the USB MSC Device Class
- *usb_comm.h/c*: Implements the USB MSC Device Class requests
- *cy_usb_dev_msc.h/c*: Implements the USB Device Middleware for the USB MSC Device Class (these files will eventually move to *usbdev.lib*)

It creates a single file named LOG.TXT. The file size is configurable through a macro and the necessary memory is allocated automatically. The USB Host can only read the contents of the file. There is no write support.

	Internally, the firmware can write data strings to the file system or erase the entire file content. As an example, the firmware writes a message every time the kit user button is pressed. To read the new file content, you must disconnect and reconnect the USB cable, so that the OS requests again for the content in the file system.

	The firmware also emulates the device being ejected at every five user button presses. This forces the OS to re-read the contents of the file system.

	The following list shows the files of this code example:
	- config.h: Configures some global options for the application
	- file_system.h/c: Implements the FAT file system
	- usb_scsi.h/c: Implements the USB SCSI protocol, which is used by the USB MSC Device Class
	- usb_comm.h/c: Implements the USB MSC Device Class requests
	- cy_usb_dev_msc.h/c: Implements the USB Device Middleware for the USB MSC Device Class (these files will eventually move to usbdev.lib)
