NXPTM LPC2XXX and LPC17XX / Re: MOD-SMB380 I2C evaluation on LPC2378-STK
« on: February 18, 2010, 12:32:21 PM »
Things where going great, then I hit a mild hiccup and ran out of time to play with it this morning. I suspect my current ping hiccup isn't a huge deal.

It appears the express C++ version is around 100 to 200 megs. That downloaded just fine last night. I had originally thought I had to get the trail VS, which is a couple gigs. So I'm golden with VS now.

It took me a couple minutes to find preprocessor starting at pull down project --> uTasker properties --> configuration properties --> c/c++ --> preprocessor. I then saw this line "WIN32;_WINDOWS;_LPC23XX;ETHEREAL" which includes the _LPC23XX that I was looking to confirm. So I'm golden.

I changed the simulation IP to Here's my ping attempt.

Code: [Select]

Also I set the simulation to look at my eth card that is used for my normal ether net activity. Here's my application.c.

Code: [Select]
static const NETWORK_PARAMETERS network_default = {
    (AUTO_NEGOTIATE /*| FULL_DUPLEX*/ | RX_FLOW_CONTROL),                // {42} usNetworkOptions - see driver.h for other possibilities
    {0x00, 0x00, 0x00, 0x00, 0x00, 0x00},                                // ucOurMAC - when no other value can be read from parameters this will be used
    { 10, 10, 10, 3 },                                                  // ucOurIP - our default IP address

    { 10, 10, 10, 111 },                                                  // ucDNS_server - Our default DNS server

I ran out of time, I might guess that that firewall is blocking traffic. I see the red an green lights on the simulation blink. Also I see it notes IP, so it appears it compiled in the new IP. Perhaps I have to assign a MAC to the simulation. Typically when my firewall has an issue, it will pop up a message inquiring if it should block or allow the traffic. I ran out of time this morning, so I'm a little blind about what the issue might be.

Any words of wisdom about this ping thing?

I'm also new to Visual Studio. The I see the express comes in several variants, I'm think I want the C++ express. Is that correct? I can choose visual basic, C#, ect.

Great, I got the zip file and I'm currently downloading Visual Studio. That's going to take a while, it's a big file.

I'm reading the PDF's and getting familiar with this setup. Thanks and I look forward to jumping into this.

I'm new here and currently reading the tutorials ect about how to use utasker. I've submitted my request for a hobby copy of utasker and should have that shortly. My first goal with utasker is to evaluate the MOD-SMB380 I just got from Olimex. I got this accelerometer because I found the on-board accelerometer had some noise issues.

So my first goal is to simply interface with the I2C and get accelerometer data out of this MOD board. I believe the digital interface of this chip will remove what I believe was analog noise issues with the original accelerometer. I'm curious if anyone one might have a recommended approach for this. I'm not sure if it's easier to get this data to show on a web page generated by utasker, or perhaps I can simply get it to display on the LCD. I'm still reading the docs and tutorials, so I'm very blind about what approach might be easiest.

I'm connecting it to an LPC2378-STK, and I can program / debug with ARM-USB-OCD both jtag and flash magic. I'm using the pre-configured windows based Eclipse and arm-elf-gcc that came with the 2378 board.

Thanks in advance.
