Gateway device
-
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...
-
My best guess is that this will probably be end Q1 2016, as I have to verify RFM69, and probably have a second look at some kind of battery backup for RTC, and sdcard reader. (I have a sdcard reader breakout board, so I should be able to verify that part relatively quickly)
We have also discussed this briefly in the "core team" we would like to have the next revision of the library out first, because support for the GW is only in development branch at the moment. So to minimize confusion on what branch to use for the board, we would like to have an official release that supports the board.

@tbowmo Ok thanks for a quick reply - looking forward to your gw! I will buy me a new gateway from ebay to secure my HA, but when you needs beta tester let me know as i already use dev.
-
I know that things are not progressing as fast with the GW. There have been some non mysensors bumps on the road, and I still have some to overcome.
If it wasn't for that daytime job, that takes up too much of the precious spare time that could be used for fun hobbies like mysensors, it would have been finished a long time ago :)
-
Didnt mean to rush @tbowmo - it looked so good at the pictures so I thought it was ready soon!And yea... that thing called daytime job takes way to much time :)
