Re: EtherTen Replacement / Reset Shield
Thanks for the reply. I obviously used the wrong search terms when i tried to find if something like the watchdog timer module existed. I had been searching for 555 and Shield, i hadn't thought to search for a simple external module. Great to know that it exists, i know what i am doing next time :) ...

EtherTen Replacement / Reset Shield
A few years ago, i was wrestling with an EtherTen locking up over time, though it was actually the W5100 chip, not the EtherTen as such. With the help of this forum, i was pointed in the direction of a 555 based external reset circuit. Having spent a few hours yesterday creating another external res...

Re: Ethernet diagnosis help
Hi guys, well i've had some success with using an external 555 timer circuit as outlined earlier in this thread....Its taken me a few days longer, as I had to find time to re-code for the change from COSM to Xively...though, i do like the new API. I've mounted the 555 timer circuit on a ProtoShield....

Re: Ethernet diagnosis help
Yeah, its a bit strange to have not at least posted a schematic on that website. But yes, if an Eagle PCB has been done properly it is based on the Schematic, so its a useful tool. Just for the sake of completeness, i have just created a new pendrive linux. Ubuntu 13.04, did a clean install of the A...

Re: Ethernet diagnosis help
Hi NGP99, thanks for that schematic. I haven't had a chance to review in any detail...im under the pump getting my day job done this time 
I downloaded the Eagle files yesterday from that site and I just took a screen grab of the schematic and attached it below.
cheers
Andrew

Re: Ethernet diagnosis help
Thanks guys... OK, so with regards the 555 hardware reset, i grabbed the wrong link from my bookmarks. The following one is designed for holding RST low and should therefore reset the W5100 as well http://www.openhardwarehub.com/projects/36-Arduino-Hardware-Reset-Circuit-Breadboard?show_all=1 With r...

Re: Ethernet diagnosis help
Hi Guys, this looks like a really cute way of doing the hardware reset without the need for timer chips etc.... So I thought I would share. http://electronicsfordogs.com/articles/self-resetting-atmel-atmega-328 My electronics brain isnt working too well this morning. In this example, circuit diagram...

Re: Ethernet diagnosis help
@Angus, i just checked and as it turns out I was using both version 1.01 on Linux and on windows at home. Though I am now using 1.04 at home. c) I discovered that for some reason either the linux version of the IDE was somehow not allowing me to use an 8s watchdog timeout, so i was forced to change ...

Re: Ethernet diagnosis help
@NGP99, unfortunately yes, there are many challenges in this situation where you have remote unattended Arduino's. To be perfectly honest I have been trying to get this working for over a year though a combination of testing at home, and visit the site, only to find another bug. Like you i have a re...

Re: Ethernet diagnosis help
Ive posted a seperate reply to ngp99 thats waiting for moderation (What triggers the need for moderation?). In some other reading i've realised I could have also implemented a watchdog timer reset in a much more simple way, (specifically for resetting) by creating a reset function that enables the w...
