Comment on DLP-RFID1 library for Linux by matt

matt — Tue, 10 Aug 2010 03:35:29 +0000

Hi Erika,
I written up some information on my new librfid1 page. When you say you need to handle it through the FPGA, how are you connecting it to the FPGA? Are you just talking to the RFID1 microcontroller via its serial port?

Anyway, hope the information that I have written up helps. If you need more info, feel free to ask and I’ll do my best to help.

~Matt

Hi Matt,
I bought a dlp-rfid1 too, but in my case I need to handle it through a FPGA.
My question is: have you information about the configuration and communication frames?

I would appreciate the help you could give me….

Comment on Updated C30 build script for Ubuntu 10.04 by Bert Vermeulen

I’m getting the same error as Paul, lots of “syntax error before __attribute__” lines. It looks like the C30 V3.23b as compiled by your latest script somehow doesn’t know about __attribute__ directives. I haven’t been successful in working out why

Cheers Andrew. I will look into your issue with using alternative directories.

I don’t know if MPLAB does anything special in its makefiles, but I have tended to use piklab which has taken care of the build stages automatically. I have quickly thrown together a generic Makefile (http://www.electricrock.co.nz/blog/microchip-c30/#makefile), which you could give a shot. I have briefly tested it with an old project I had lying around and it complied successfully.

In terms of automake, I have little experience with it but I think it’s overkill because you don’t really need automated installing or to deal with building on lots of different systems.

Wow, you already fixed it. I don’t use the term “hero” often … but here …

Anyhow, I was installing it to /opt/pic30/ as a regular user on Ubuntu 10.04 x86 32bit. It only seemed to work if I commented out the SUDO line and started with a completely empty /tmp/c30, though.

Now to port all the absolute paths of the MPLAB outputted Makefile into relative paths, and see if it works. Unless you can recommend sort of clever automake setup?

Paul, I built C30 v3.23b on Ubuntu 10.04 i386 and tried running the test script. However, I haven’t yet been able to replicate this error. I intend to put up some binaries when I have time to make them, which should hopefully mitigate the problem.

Yeah, sorry for the lack of updates recently, it's been a busy time for me. Anyway, I have updated the install script... see here.

You might need to update your script slightly? they are now on v3.23B, and some of the files aren’t available (unless I just can’t find them).

Distribute binaries … please? The Windows C30 compiler is so unbearably slow.

Hey matt,

I seem to be having the exact same issue as Mark.
I am using Ubuntu 10.04
