C RISCV RTOS

Currently being developed for the FE310 on the SiFive HiFive1 Rev. B board.

This is mostly meant for educational purposes

Honestly the best thing to come out of this is the runtime environment set up. It works for c and c++

A simple header only command line argument parser

  ArgumentParser parser("Argument parser example");
  parser.add_argument("-v",             // short argument

                      "Verbose level",  // description
                      false             // is required
  );
  parser.parse(argc, argv);

  if (parser.exists("verbose")) {
    switch (parser.get<unsigned int>("verbose")) {
      case 2:
        std::cout << "an even more verbose string" << std::endl;
      case 1:
        std::cout << "a verbose string" << std::endl;
      default:
        std::cout << "some verbosity" << std::endl;
    }
  }
}

Example output:

> program -v 2
an even more verbose string
a verbose string
some verbosity
> program --verbose
some verbosity

Open Source Smart Watch

2017-12-09T00:00:00+00:00

The original inspiration for this project came from Jared Sanson here http://jared.geek.nz/2014/jul/oshw-oled-watch

This is my attempt at creating a “smart” watch, however it will only be as smart as I make it so we’ll see how well I do.

You can follow the project’s Github page here

The processor I chose is in the PIC32MZ EF family, specifically the PIC32MZ2048EFG064 I had several reasons for choosing it. A big one was its large, for a microcontroller, amount of program memory and RAM. My goal is to be able to use MicroPhyton to write apps but I’m not 100% sure I will be able to without adding a RAM chip. I also chose it because it can act as a USB device such as a mass storage device that I can just plug into my computer and transfer the python scrips over. The chip also has a parallel master port which makes it easy to control a compatable LCD. There are plenty of great things about this chip, its a beast. It’s price is pretty large though at about $11 USD but since this is a one off design I’m not too concerned.

Planned Features

1.8 inch 128x160 RGB LCD
Real time clock (it’s built into the main processor)
Bluetooth communication with phone, hopefully sync notifications and be able to answer calls however there are no plans for a mic on the watch itself
USB HID/Mass storage communication for easy programming of apps
400-500mAh battery with 500mA charging circuit
Accelerometer
Magnemometer
Single/Double tap sensor for tap to wake

Hardware

This is the current schematic, I’m finalizing the design and trying to make sure I haven’t made any mistake (but I probably have)

Blog Update 2017-05-30

2017-05-30T00:00:00+00:00

I have updated the theme to my blog and will hopefully keep it more updated than I have been (but probably not). I will try to add more posts along with using it as sort of an online portfolio.
