Images of the latest pcb's (Before SMD assembly)
Unfortunately I "injured" my back today (aah, maybe not injured, but feels like it :() so I'm on strong medics to keep the pain away. That means that didn't get around to do the SMD assembly today as I planned, as I can't sit at the desk for a longer time.. hope that it gets better during the weekend.

yeah :smile:

A small update before I hit the bed tonight..
I've got radio up and running on the SAMD, and got the first message from one of my sensebender micros through to my pc.
It's still in debug mode, using a serial port on the samd as output (And my logic analyzer to decode the serial stream). So no ethernet / wifi or the like up yet.
The next step will be to have it use USB instead of the serial port..
-
:+1: good work!
-
Great! I will buy one of these as soon as this is working as you want :)
-
a new small update..
Got it working as a serial GW.. Receiving the first messages from one of my sensebenders..
Also got the ethernet going, this is not integrated with the mysensors parts though, as I have to refactor nrf / ethernet libraries a bit, in order to support multiple (HW) SPI interfaces..

Sounds great. I'm definitely interested in using this as a gateway as well. Any chance you're going to add SPI transaction support to those libraries (more info in my post here)? I know there are RFM library versions that have that as well (see here).

Nice - I forgot that you upgraded and weren't using a 328 processor.

A small Christmas progress update.
I got external eeprom, and w5100 module running now.
That means I have a working ethernet GW running with nrf24 running on SAMD.
I'm waiting for rfm69 modules from China before I can verify that this part also works as expected.
An ethernet GW with hw signing is using 35.988 bytes, or 13% of the available flash size, which is 256kbyte. So we have "plenty" of room to do other fun stuff on the GW
-
I have updated the original posting, with updated hardware details.
- Removed the ESP8266 from the feature list (It's supporting the mysensors library native).
- Removed onboard SPI flash, but will probably add sdcard / micro sdcard reader
- Might add battery backup for an onboard RTC.. (the SAMD have an onboard RTC, only using 2-3uA in low power RTC keep alive mode)
-
@tbowmo: I love your project , I can't wait to try your awesome baby GW :smile:
I agree with you with your updates too. RTC could be interesting.
Humm, when I see price and memory, I am very tempted to update one of my sensors board with atsamL21 family to give a try...do you have an advice for a good&cheap jtag programmer??? -
I'm using an atmel jtagice3, with a custom PCB for converting from jtagice3 pinouts to standard cortex m0 debug connector. (have plans on selling this converter board elsewhere sometime in the future)
I got the jtagice3 5 years ago as a gift from atmel, for attending a course on their xmega series of MCU's. Don't know of any cheaper alternatives out there
-
Hi. How far from finished is this gw? It looks awesome. My is acting fishy and I need to order a new one. I can wait some for this if you have some sort of eta.
-
oki, thx :smiley: I see for connectors..I will look if I can find a cheaper "working" alternative for atsam...
