README
**Portfolio Manager** is an application for interfacing an [Atari Portfolio](https://en.wikipedia.org/wiki/Atari_Portfolio) vintage portable computer with your desktop PC. It works together with an [Arduino](https://store.arduino.cc/pages/nano-family) to connect the Portfolio Parallel Interface Adapter to a USB port on your computer. With this hardware, Portfolio Manger supports the internal file transfer protocol of the Portfolio.
## Requirements
To use this software you will need the following:
* An Atari Portfolio
* An Atari Parallel Interface Adapter
* An Arduino (Arduino Nano)
* A DB25 breakout board
* A PC running Windows
## Features
Support for all built-in Portfolio file transfer server features:
* Sending files to Portfolio
* Receiving files from Portfolio
* Listing files on the Portfolio
PofoManager also supports uploading pre-compiled firmware to a number of different Arduino models.
## Download and Install
You can download the latest release installer from here:
* [PofoManager v1.0.2](https://github.com/codaris/PofoManager/releases/download/v1.0.2/PofoManager.msi)
Download the above file and open it to install PofoManager on your computer.
## Arduino Connection Diagram
For compatibiltiy with the Atari Portfolio file transfer server it is only necessary to connect to pins 2, 3, 12, 13, and 25 on the DB25 connector.

## Getting Help
You can get help with this application by using the [Issues](https://github.com/codaris/PofoManager/issues) tab in this project.
## Building the Project
This project consists of two parts, the **Arduino Firmware** that drives the connections to the Portfolio over the parallel port and the **PofoManager** desktop application that communicates with the Arduino over USB.
### Building the Arduino Firmware
The Arduino firmware is located in the [Arduino](https://github.com/codaris/PofoManager/tree/main/Arduino) directory of the project. This can be built with the [Arduino IDE](https://www.arduino.cc/en/software) and installed directly onto an Arduino. For this project, I've chosen an Arduino Nano but most models of Arduino should work without issue. You can edit the [Porfolio.ino](https://github.com/codaris/PofoManager/blob/main/Arduino/Portfolio.ino) file to change the pin mapping if necessary.
### Building PofoManager
The desktop component is written in C# for .NET 6.0. It can be compiled by the community (free) edition of [Visual Studio 2022](https://visualstudio.microsoft.com/vs/community/). Simply open the main solution file in the [PofoManager](https://github.com/codaris/PofoManager/tree/main/PofoManager) directory of the project and select `Build Solution`.
## Change log
**Version 1.0.2**
* Removed serial port polling to decrease CPU Usage
* Increased timeouts to 2 seconds (needed for some devices)
**Version 1.0.1**
* Initial release
