Hi. This is my first project post (but not my first project), so sorry if I've done anything wrong. I'm not sure if I'm OK to post this, as it is an RC model, but … Read more

KiCad problems on windows 8

Hi

Don't know if this is the best place to ask about this sort of stuff, but here it is:

free 2d CAD

Hi.

Since secondary school, I've been using a student version of the cad package they use (2d design). However, it is awful, and is even more so now I've left, as I can't;

LCD

Hi.

Has anyone tried using These LCDs with an arduino? I'm not sure whether they're HDD44780 compatible or not, and I can't seem to find much of a datasheet.

Thanks in advance.

Assembly PIC problems

Hi.

For a collage project, I have to do some PIC programming in Assembly. I've made a start, but I'm having trouble defining some variables. Out of the 11 variables I'm using, it is only naming the middle 5 when I simulate it. They're all pretty much identical appart from the name and the position in the memory. Does anyone have any suggestions as to why this is happening?

Sorry for the lack of info. my code's at collage, and I'm not sure of the software (I think it's VPIC, or something similar).

Thanks in advance

Atmel RF ATmegas

Hi.

Has anyone attempted using these? I was wondering how hard it would be to use them with the arduino bootloader for my as-yet-not-started RC system project (I will get round to it soon, hopefully). The Zigduino seems to use them, and they've supplied a library to operate the in-built radio. I'm just wondering whether I'd have to be careful with PCB layout etc. to avoid interference.

Charlieplexing

Hi.

Having got the processing/arduino serial sorted, I thought I'd have a go with charliplexing. I downloaded this library, and wrote a bit of code to try it. However, whenever I try to verify a sketch using it (including the demo sketch), I get this error;no matching function to call to 'Charlieplex::Charlieplex(byte [3], int)'. I've tried re-extracting the library, but with no success. Does anyone have any ideas?

If this library is broken, does anyone know of a better one for charlieplexing?

Serial monitoring

Hi.

Does anybody know of a decent freebie transparent serial monitor? I've been having some trouble with processing and arduino, (see this), and I'd like to be able to compare what processing and the arduino terminal are sending so I can find the problem.

Thans in advance.

Trouble with arduino/processing

I've been trying to teach myself Arduino and Processing, and I've been hitting a few problems. I had a previous post Here, but it was getting a bit crowded with code, so I thought I'd start a new post.
