GLCD not getting time, OKG not Starting without a reset

 Hi all from Australia.

First off, thank-you to the Open Energy Monitor team for making the awesome hardware and software available to everyone. I have a couple issues and would appreciate a little help.

1.

My first issue is my GLCD screen doesn't seem to get the current time from enomcms for some reason. I am running the latest enomcms software from github and have installed it on my NAS. It all seems to be working fine. Any ideas?

2.

My second issue is my OKG (with wiznet w5200) doesn't start up without pushing the reset button. When I plug in the 5V DC supply, all LED's turn on including the ethernet leds. It doesn't matter how many times I plug/unplug the power supply I get the same problem. The only way to get it going is to push the onboard reset button and it all seems to work. I have cut the trace and soldered the additional capacitor as per here.

Hopefully my GLCD and OKG files are attached.

Cheers

Nigel

 Hello Nigel, good work on building up the system. I can answer question 1, I still need to add the time request code to the wiznet based firmware, will try and get on to that. Will ask Glyn if he has any ideas about the reset issue, I dont think its something we have experienced.

All the best, Trystan

 Thanks Trystan, let me know when the wiznet firmware is updated and I will try it out.

Hello Nigel, ok just got it to work, if you download the latest version that should do it: https://github.com/openenergymonitor/Open-Kontrol-Gateway

I too am having that power-on reset problem - and using the current code (downloaded 4/9/12 - Git thinks it's still the same).

[Edit]

It's tied up with the rate of rise of the power supply voltage!

[Edit 2]

I have soldered a 0.1 uF capacitor across the reset switch contacts, and that seems to work (unless the power supply voltage is applied really slowly).

Just had an email from Robert noting that the 0,1uF capacitor across the reset and GND line does not allow code to be uploaded. If the capacitor is reduced to 10nF this seems to solve the wiznet hanging issue and allows the the reset to happen automatically when uploading code via FTDI.
