Fusee Launcher for the openschemes SAMD21 Loader board. Based on [https://github.com/atlas44/sam-fusee-launcher sam fusee launcher]. Build and tested with Arduino SDK. ==User guide== ===Source Code=== * [https://github.com/electronrancher/sam-fusee-launcher Firmware] (Compile and flash with Arduino, forked from sam-fusee-launcher) (you probably want this one if you want to hack on stuff). * [https://github.com/electronrancher/SAMD_Fusee_Multiloader Multiloader] (Compile and flash with Arduino, forked from the V1.0 firmware just above) * [https://github.com/electronrancher/uf2-samdx1 Bootloader] (Compile with GCC and flash with SWD, forked from uf2-samdx1) (You probably don't ever need to touch the bootloader, so you may not care about this one) ===Install a Pre-built Firmware=== *Download a firmware zip file from the [https://github.com/electronrancher/sam-fusee-launcher firmware directory] and open. *Plug the SAMD Loader into USB, and double click reset *Drop the 3 files from inside the zip onto USB. They will be autoflashed as soon as they are written *Unplug SAMD Loader, it's now flashed to the new firmware. ===Optional Multiloader Firmware=== A pre-built Firmware can be found [https://gbatemp.net/threads/my-dongle-project-internal-external-samd-loader-with-cr2032-holder.513755/ here]. This firmware was inspired by, and borrows from, mattytrog's implementation of Gemma multiloader. Thanks mattytrog. *To use, plug in normally and power on. While searching for Tegra, the device will show 1, 2, or 3 quick blinks to signify which payload is active. *To change payload, hold the change button (D1), the device will cycle through 1, 2, then 3 blinks to indicate payload selection. Let go of change button once your desired payload is indicated *To store payload, momentarily press the store button (D0). The activity LED will light for 1 second to indicate flashing and upon the next reset, your desired payload will be automatically selected. The rest is the same, device will blink 1-3 times while searching for Tegra, then give a short-long "Ta-daa" blink as the payload is sent and activated. At that point, you're done! Unplug and switch the loader off. ===FAQ=== '''Q. What is it?''' It's a small SAMD21 board with an onboard CR2032 battery holder. It can be used to send fusee gelee payloads. '''Q. Why did you build it?''' I wanted a board that was instantly-on, and that I could reprogram with open source tools. '''Q. How big is it?''' 24 x 25mm. '''Q. Can it fit inside my console?''' Yes, with the battery clip and other tall stuff omitted. I made the USB pads big for easy soldering. '''Q. What do I need to get injecting?''' A CR2032 battery, a USB micro b to C cable, and an RCM jig. All can be found on ebay or Amazon for a low cost. ==Media== '''Placing the samd loader''' ([https://www.youtube.com/watch?v=Z2HUrrbz8lQ electronrancher]) <br> <youtube>Z2HUrrbz8lQ</youtube> '''SAMD Loader in action''' ([https://www.youtube.com/watch?v=HImP8QRGi0U electronrancher]) <br> <youtube>HImP8QRGi0U</youtube> '''Pick and Place monitor''' ([https://www.youtube.com/watch?v=cneiqwa-cQI electronrancher]) <br> <youtube>cneiqwa-cQI</youtube> == External links == * GitHub - https://github.com/electronrancher/sam-fusee-launcher * GitHub - https://github.com/electronrancher/SAMD_Fusee_Multiloader * GitHub - https://github.com/electronrancher/uf2-samdx1 * GBAtemp - https://gbatemp.net/threads/my-dongle-project-internal-external-samd-loader-with-cr2032-holder.513755
