SAMD21 introduction. Since it is quite new, there is not so much information about it on the Internet. See the article and how to buy here. I have developed a sophisticated e-bike computer, called the E-bike cable killer; it requires a small but powerful Arduino microcontroller. E-bike computer with SAM-D21 Beforethe only faster Arduino alternative was the Arduino Due, but the processor has pins and that is too much of a good thing.
The most important pin peripheral functions are indicated with letters in the schematic symbol:. Pins may have many other peripheral functions, but in order not to lose overview, these are not indicated with a letter in the schematic symbol:. SAMD21 partnumber. SAMD21 configuration.
The ATmega always needs an additional controller for programming. This simplicity saves costs and board space. All we need is the SAMD21 with pre-programmed bootloader, a crystal and some capacitors: Note that the Arduino Zero board contains a lot of components; however these are in principle not all necessary.
With some exercise, this TQFP48 chip it can be soldered by yourself; see here how to do it. You will, however, find out that the soldering is not so easy like in the examples. Maybe they have taken 10 videos and shown the best:. Do you have any comments about the website or problems with shopping? Please let me know. About this website Contact.

If that happens, update it before doing anything else by following the instructions Atmel Studio gives you. Then click OK and Atmel Studio will create the project. We see the Atmel Studio has already created some skeleton code for us that we can modify.
To program the board with our simple firmware, all we have to do is click the green play button. If instead there were compilation errors, you would see those instead. I'm the founder of Zippy Robotics and creator of Prometheus.
I'm interested in electrical, mechanical, and software engineering and hold a bachelor of science in physics from the University of Maryland.

It's split into a number of pages, including:. That's all you'll need to get started. Eventually you'll want to solder something to the board. If you don't already have soldering tools, a soldering iron and some solder may also come in handy. You can choose your own adventure when it comes to soldering connectors into the boards.
Any of these headers or wire may come in handy:. A row of headers - break to fit. Used with custom PCBs or general custom headers.
An assortment of colored wires: you know it's a beautiful thing. Six different colors of solid core wire in a cardboard dispe…. Single row of holes, female header. Can be cut to size with a pair of wire-cutters. We use them exte….
This is a 6-pin female header, with extra long legs -- great for stacking Arduino shields. Pins are spaced by 0. This isn't to say there aren't benefits to the ATmega's: they're well-documented, have huge support in the community, are simpler to wrap your head around, and can operate at 5V.R&D #24: How to use the Atmel-Ice, step by step
There'll always be a place in the world for the ATmegaP, but -- especially as price point's get closer -- there are many good reasons to consider the SAMDFor those of you who have used the SAMD21 from sparkfun and are looking to burn a custom bootloader to the ATSAMD21g18 chip microcontroller unit MCU or develop your own printed circuit board application, this instructables page will take you through the necessary steps for burning the bootloader operation.
Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. This instructables page will assume you have some soldering experience. If you don't, no worries there is only one component you need to solder together. Below is a video for an introduction on how to solder made by electronhacks on youtube.
ATSAMD21g18 Bootloader With J-link Debugger
You will also need to download Atmel Studio. This may seem like a daunting thing to understand, but this is important for those of you who are looking to use the ATSAMD21g18 chip for printed circuit board applications. So what is a bootloader? Well a bootloader is a small code that allows you to upload firmware source code that makes your microcontroller adaptable for different applications. When you buy the ATSAMD21g18 chip from a electronics vendor such as digikey, you will need to do whats called "burning the bootloader" to make it compatible to program over the arduino IDE.
While not all the pins are required, these are the essential ones:. Follow the link to the Sparkfun Github Repository and download the zip file and unzip it to your preferred destination. Click on the file and select open. Finally, select program right next to flash and you will get a response in the output prompt saying: "Verifying Flash Congratulations you have successfully bootloaded the SAMD21 chip!
Question 8 months ago. Hi There! Like will it work with the bluetooth chip on it? Question 1 year ago. I am having issues after following your instructions as you described. I also tried uploading the. I believe the bootloader is being uploaded but my computer still does not detect the board via USB.
Any ideas? This is great! Do you think the same process would work for bootloading.
I don't think Adafruit provides the. I'd love to make an Adafruit M0 express board in a smaller form factor. Please help me in this regards and reply ASAP. Answer 1 year ago. Reply 3 years ago.This updates a previous blog entry with more details and minor corrections. In terms of hardware, this article also assumes you own an Atmel ICE programmer.
You will need to install some software packages to program your SAMD21 board. On Debian Linux, you will use your package manager e. On the Mac, we suggest using homebrew to install the different tools described here. You will need to fit a 2x5 pin 1. You don't necessarily need to solder the header to the board: just plugging the header is usually good enough to establish electrical contact.
You will then plug the corresponding connector on the Atmel ICE. Since the connector is not keyed, there are two possible ways to plug the Atmel ICE on the board. If you try one way and it doesn't work, just flip the connector around!
On a Linux, with a Debian style OS, you will need to refer to your package manager apt-get or aptitude. Once installed, the next step is to set up OpenOCD correctly. For this purpose create a file called openocf. You can test your openocd. You should get an output similar to this:. Now you can plug the SWD header in the board you want to program. Don't forget to power the board separately, with USB for example. If you launch OpenOCD again, you should get the following output:.
Now, while OpenOCD is still running, we can test that gdb works by typing arm-none-eabi-gdb -iex "target extended-remote localhost" in another terminal window:. We will make it blink to test our setup. If you have another board it might have an LED on a different PIN or none at all, you will need to adapt the code below e. There are in fact several ways to achieve the same result on the SAMD21, we are just showing one for simplicity.
In fact, you will only be using a very small subset of this big framework, and you will be able to delete a large part of this framework if needed later.
Programming the SAMD21 using Atmel ICE with OpenOCD (updated)
When uncompressing the file, you'll get a directory named xdk-asf Now the following steps will need a small customization depending on the microcontroller you have.
If you followed all the steps above, you should have the following files in your current directory:. Now, you are ready to run the program.It features:. This collection includes compiler, assembler, linker and Standard C and math libraries. Most of these tools are based on efforts from GNU www. For more information please refer to the release notes.

Note that the bootloader has nothing to do with the package file for the pin definitions. Project with a SAMD Burning the bootloader is only possible by use of the programming port, not the native USB port. The EDBG takes care of the programming. Arduino Zero modifications.
Note: there are cheap Arduino Zero board variants without the programming port, you can't use these. Remove the resistors R and R, see the image. Use the free pads of the removed resistors for soldering the wires to. Note: the 5 pin JST connector is optional, you can use the 1. TQFP48 test socket from eBay. TQFP48 test socket wiring. Wire the JST socket connector. Solder the two capacitors to the board.
Wire the board according the schematic on your own understanding. Sometimes we have to cut some traces on the board. First check if you can burn the bootloader into the on-board SAMD21 as before; first turn the switches in de right position. To burn the bootloader into the external SAMD21, put the switches in de other position.
