152  Using Arduino / Microcontrollers / Re: How to check amount of free ram (and used) on: March 01, 2011, 02:11:58 pm
It works, fine. But C:\Program Files\arduino-0022\hardware\tools\avr\bin is not in my path settings, needed a bit of work before avr-size would run. I copied the exe, is there any reason to include the in path settings. How do you actually do it.

By the way, the numbers seem to be in decimal, not in hex, am I right?

This (too) should be in IDE.

Hm. Why I did not see it yesterday. Thanks!

Thanks, Compile time memory check is good enough for me now. But I found only old elf-files. How do I get those now of my current projects. Or some way check memory at compile time.

I have to search for some of my older posts and then click my sign. There is a My Messages menu on top of the page. I have no messages coming or going but I want to see my posts to forums easily.

Well, C was written to help write an operating system (UNIX), where you are hitting the hardware and want to be able to do pretty much anything.

And now I'll duck. :-)
Heh. Where do you hide, I'll need to hide after this. My turn. One thing which irritates me in C is: I started with assembly programming a long time ago. There you had to know exactly what was a address and what was data in that address. And how to mix and handle both. Exactly. In C a variable is sometimes data and sometime address. I hate that a lot. Please note I like (valid)pointers.

It feels like C was designed by an idiot(s) who didn't understand indirect addressing.
157  Using Arduino / Project Guidance / Re: getting computer to recognize arduino device as HID/keyboard? on: February 28, 2011, 04:34:05 pm
As your link shows a common Arduino board I know one answer. Different kind of USB devices need different drivers. Arduino uses serial USB chip and drivers.

Usb serial chip on Arduino board uses serial port driver in the computer. You need HID driver for that chip. I dont think it exists. But there may be a chips for USB HID device, but that is an other story. They must of course be adapted to Arduino.

With a little electronics, it is possible to make Arduino work as a non USB keyboard. Again an other long story.

Does the IDE work with W7 othervise? I tried it once and got problems. Don't ask what problems, I don't remember.

My project is getting bigger on a XP Pro computer. I am slowly getting worried about ram. There is nothing about this in project folders. What can I do, except clean up my project.

By the way, am I the only one who can't find a suitable forum among Arduino forums.

I was probably sleeping with my eyes open and copy pasted this kind of rubbish into my code. Compiler did not give any errors.

There is no reason not to use XMODEM, KERMIT, or AX.25 on Arduino.  Or you can go all the way to TCP/IP.

As far as I know, the efforts to create more general purpose networking protocols over async serial (as opposed to file transfer protocols) (like PCNet) never really went anywhere (they were essentially overwhelmed by newer networking technology like Ethernet and SLIP.)
Ok
But is there source code for those protocols. I'm thinking something which is also used in Windows. Ethernet works, but serial bus is in every Arduino. Besides, I think those protocols should be already in the library, there are so much other sw for Arduino.

The standard serial connection is just plain serial, you can use it for whatever kind of data you wish, there are no error correction / detection protocols unless you choose to incorporate your own.  I just use a checksum if I want a bit of error detection.  It uses the same old 3 pins (and JUST 3 pins, theres nothing else...).
Those serial protocols work on serial bus(plain old). And just like with other computers, a reliable way of transferring data with Arduinos is needed.

I do not completely understand what you mean by your post, but there are two ways to handle data flow, hardware and soft. I think hardware flow control cant be used because it is hard to use and one signal is used in in Arduino programming. What I know, those (once) common protocols do not rely on hardware flow control. Data is sent in packets. But we do not need to know any details, if the transfer is handled in library.

I understand that there is no room in Arduino to receive large files, but files can be 1 byte long for instance.

I have often seen people asking how to handle binary data transfer between two computers. That is, between Arduinos and/or pcs.

I know that was solved long ago with protocols such as zmodem, xmodem and so on. With those you can transfer binary data (files) between two PCs. All you needed were three wires (tx, rx and gnd) and a free serial port.

Is there anything similar protocol for Arduino?

The regex parser has issues with comments that contain comments and with comments that contain quotes.

Yep. I can see it now, expecially when I know what was wrong. That new kind of error message was not helpfull. "regex parser has issues" good to know. One comment still, my extra quote wasn't in comment
 smspalaute=gsm.SendSMS("+35phonenumber", teksti");
I though there was a problem with GMS library.
165  Forum 2005-2010 (read only) / Bugs & Suggestions / Re: A very long nonsense error message from compiler on: June 03, 2010, 08:12:40 am
I think I fixed it, this was broken
Code:
smspalaute=gsm.SendSMS("+35phonenumber", teksti");

There were an extra " because I removed a fixed text "message" and made an error.

But the error message did not help at all. That is a problem.
