You can write functions to manipulate the design of a basket and then make it from that same interface. It might be a stretch but I was imagining that you could have an interface in OpenFrameworks where I did this looking ahead to my final project, which is about basket making. OpenFrameworks, morphing between a spiraling sphere and a torus. Over the weekend I had been looking at Joseph Choma's book, Morphing, which deals with distorting and morphing between

If you are configured to the same serial port as the hardware, you're good to go! The code for this along with the code for my Essentially, you create an ofSerial object, which allows you to read and write to a serial port.

This video from Dan Buzzo really lays out how to I wrote my code in Xcode.Ĭommunicating between OpenFrameworks and a piece of hardware can be done in a number of ways but I chose to use serial communcation. Workflow, rather than for performance reasons. I mostly chose OpenFrameworks this week because I like the OpenFrameworks also allows you to publish on smartphones or as a native application. Whereas Processing is written in the Processing IDE, OpenFrameworks can be written in any IDE. OpenFrameworks is similar to Processing in its goals and functionality. OpenFrameworks is an opensource set of tools written in C++ that is geared towards creative coding. I decided to use OpenFrameworks to program my interface this week.

Once theīootloader was succesfully flashed, I just had to install the Adafruit core in the Adafruit IDE and was up and running. You can find the mappings here.It is possible to access the other pins through port manipulation, but I haven't gotten that far yet.
One thing to note about this is that though my design breaks out most of the free pins on the SAMD21, the Adafruit core only has pin mappings for 6 of these pins, because that is all that they makeĪvailable on the Trinkets that they sell. I used the Adafruit Trinket M0 bootloader. This is more less the same process as using edbg. Instructions for how to do this can be found here. I used the MAXDAP provided to flash bootloaders to clank along with pyOCD. It's best not to haveĪnd an ATMEL-ICE in the architecture shop to flash bootloaders to my boards, but seeing as we no longer have access to campus, I had to try something different.
I learned from Jake that USB is a medium-fast protocol so the physical design can really effect their functioning.
SAMD21 match the orientation of the corresponding pads on micro-USB, which is flipped on standard USB. The reason for the micro-USB is that the orientation of the USBDM and USBDP pins on the I used solder paste, which made this more straightforward.
Making the board was fairly straightforward though soldering the micro-USB was a bit tricky. PNGs for this design at the bottom of the page. Significant amount of editing in Rhino to rectify this, which is probably not the best solution, but it works. One issue I had was that the footprints I had for both the micro-USB and the SAMD21 didn't have enough clearance between pads for a 1/64" end mill. Stock and made the back a ground plane, making the routing much simpler. This board is essentially an Adafruit Trinket M0. This week I made a SAMD21 board based off of Jake's design found here.
