31  Using Arduino / Networking, Protocols, and Devices / Re: Netserver example is not working here with the Duemilanove on: October 14, 2013, 05:52:54 pm
I tried to use 10.0.0.33 for both sketches and they did not work. Then without the IP part the example from Arduino IDE worked. The code from Arduino playground did not do anything visible either way.

By the way, is this correct?
Ethernet.begin(mac, ip, gateway, gateway, subnet);
The Gateway is there twice. This is from the playground sketch.

That is when my local net is using http://192.168.100.16/ for the shield when it works, I should give it an address starting with 10.0.0.0 or   172.16.0.0 .  I'll try that.

My modem is Bewan ibox IAD ARV4510NPW

Arduino got always http://192.168.100.16/ for its IP. The modem uses NAT, but I could not find any other settings for NAT or local LAN.

If I use Ethernet.begin(mac, ip, gateway, gateway, subnet); it does not work, but this shortened form using DHCP? works. Is the Windows the problem. I use Windows 7 pro and a 4 port bridge, my ADSL modem is a DHCP server too.

I tried but it did not work. But can you make it print it's IP address. Because I got the examples working by using Ethernet.begin(mac); But then I had to use whatever IP it got. I come here to write a new post about that.
I dont know why it works but I sure would like to know.

I had the Duemilanove and Ethernet shield together in front of me, and tried some examples from Arduino web site and IDE. Ethernet client seems to work and DHCP, but the server does not. That is a pity, because that would interest me most

The shield is an old card too, it does not have HW for the SD card. It uses a Wiznet W5100 chip. I have no extra power, just the USB, but other examples work with it, so should the shield too?
37  Products / Arduino Due / Re: How can we measure the amount of RAM consumed by a code in Arduino Due on: August 23, 2013, 01:37:32 pm
Have you got an answer yet.
There are ways to to do it with other Arduinos. Is it different than with DUE.
38  Products / Arduino Due / Re: Just for confirmation: DUE cannot have external parallel RAM? on: July 31, 2013, 09:57:57 pm
Yes. I have seen that thread. "    
Parallel library for Due External Memory Bus/Static Memory Controller "

What is NRD?
39  Products / Arduino Due / Re: Just for confirmation: DUE cannot have external parallel RAM? on: July 31, 2013, 03:45:28 pm
I am not sure what kind of RAM you mean, but you can use ordinary parallel RAM (and ROM), if you have some IO pins left and multiplex them to drive what the memory needs. Was that what you meant by banking?
40  Products / Arduino Due / A new ARM from Atmel on: July 31, 2013, 03:34:48 pm
I just got a news letter from Atmel with a title: A new ARM Cortex MCU and wireless wizardry - Atmel eNewsletter July 2013 .

Does this mean that there could be an even faster/bigger/better DUE shortly? The newsletter is just an AD, no true info in it in my opinion.
41  Using Arduino / Installation & Troubleshooting / Error in Arduino Mega 2560 R3 board grounding? on: March 22, 2013, 03:46:04 pm
I was looking at ATMEGA16U2-MU datasheet pages 186-188 very carefully and noticed that USB ground should be connected to UGND but also to overall ground of the board. But in Mega R3 schematic there seems to be jumper or 2 pads close to each other but no solid connection. There is a text "GROUND" close there too.

Am I interpreting this wrong and what is the purpose of the partial grounding?
I have no board here so I'll have to ask.

Answer: Perhaps, if their power supplies are connected slightly wrong. I thought that power from the usb should be connected to UVCC. But it looks like that not now, UVCC should go to 5V. 
43  Using Arduino / Installation & Troubleshooting / Re: Do Arduino Mega 2560 R3 USB break easily? on: March 21, 2013, 01:20:43 pm
I just looked through the ATmega16U2 datasheet. I could not find anything about the order which power supplies should be connected. Have to study some more.
44  Using Arduino / Installation & Troubleshooting / Re: Do Arduino Mega 2560 R3 USB break easily? on: March 21, 2013, 12:30:21 pm
I must check this. Either I just cut the positive USB power trace or connect it to the main +5V.

You helped. Thank you.
45  Using Arduino / Installation & Troubleshooting / Re: Do Arduino Mega 2560 R3 USB break easily? on: March 21, 2013, 12:21:52 pm
There has been a problem bricking the usb chip if you supply power to the +5v bus without disconnecting the +5v bus from the usb power bus. I do not know if that was your problem since you have a custom board.

I have noticed that our Mega board is a little picky about the order I connect the power and the usb cable. (But I thought all Arduinos are picky about this?) Is this a somekind of latch up problem. I think I'll cut the usb + power trace.

Edit: tried to make the meaning a little clearer in (But I thought all Arduinos are picky about this?).
