A good question, I think that I have tried both at the same time.. At least I know, that the W5100 and rfm69 is working separately, and they are using separate hardware SPI ports, so they should also work combined.
HI @tbowmo
I am developing a similar GW board with a different SAMD chip.
Just one silly question. Could you point me in the right direction regarding which files are the ones that need to be modified so as to tell the compiler that W5100 will be connected at SERCOM1 and RFM69 at SERCOM2 for example.
Thanks, regards. -
Sorry @tbowmo. I can't find those files in mysensors library. Are those files included or will be included with the release of your GW?
thanks
-
As said they are located in the board variant files. They are in their own repository.
Look here https://github.com/mysensors/ArduinoBoards
And here https://github.com/mysensors/ArduinoHwSAMD
The first is just an installation repository, it contains zipped files from the last one.

I don't think so, @hek has already pushed the person responsible for the calculations a couple of times via skype.. I do not know what is happening out there (one of the disadvantages of having manufacturers so far away, you can't just stop by to see what they are up to)
-
@tbowmo @hek Would you guys maybe willing to try any other company? There are multiple PCB manufacturers in Hong Kong. My personal experience with Itead is mixed. Their support is extremely poor - It looks like one person responsible for supporting multiple products. They are cheap, but struggling with fast expansion launching their own IOT products (Sonoff).
-
we have looked at a couple of other manufacturers in China / Hong Kong area.. But found (back then) that Itead was the best solution, as they would handle manufacturing, stock, and shipment for us, and pay us a commission of the sale which makes it extremely easy for us to handle product launches
With the other manufacturers we had to buy 100/200 units, and handle stock / shipment ourselves, and with the limited time for the project (as most of us have families and daytime jobs to take care of, besides of bringing new products into the world), this is not a feasible solution..
My contact person at Itead, promised that she would get the quotation guy to answer me today. So let's see what happens
-
I'm not sure. But I think I read somewhere that the manufacturers in china are closed due to holiday.... At least I think I read that on aliexpress.

Almost ready for a last roll of prototype.. I've updated github with latest changes, if anyone cares to have a look at it, and give me some feedback on it, then it is now! during Easter, I will (hopefully) do the last prototype spin!
@tbowmo Hi! Very cool design, I especially like using of ARM microcontrollers. I have a lot of projects with SAMD20, and I want to give you a little advice for your future revision of your "Mysensors Gatevay". When I had problems with my devices work (there were crashes and hangs) I found the circuit of evaluation board called "SAM D20 Xplained Pro". After examining this circuit I saw that they apply more capacitors in the power supply than I. And I thought that use just one capacitor 100 nF not enough. So, I corrected the filtering circuit in my devices and everything worked perfectly. Below I'm showing the filtering scheme:
-
Thanks for the tip.. I took heavy inspiration from the arduino zero, which only has 100nF capacitors for decoupling.
I haven't seen any problems with stability on the prototype GW's that I have build, we also have 5 production sample GW's out in the wild, at a couple of the core group members, and I have not heard any problems from them either.
Anyways, I have noted it, and will take it into consideration if I/we decide to do a new revision of the schematic / layout.
