I’m currently:
- Running linux on a gumstix
- Running gdbserver on that gumstix.
- Debugging a program on the gumstix using gdb on my laptop (which is running linux)
- Remotely debugging the msp430 that’s connected to the gumstix I2C bus
Oh, but wait, msp430-gdbproxy and friends aren’t free. Arrrrgh. I can feel my soul dissolving.
If I ignore the dissolving for now, it’s all amazing. So much debugging.
Just found an interesting article on Circuit Cellar about a guy who linked an XBee to one of those Microchip ethernet chips. Nice.
Was trying to locate a button cell on Farnell. Of course, I for some reason forgot that Farnell don’t want me to be able to find the product I want, and foolishly selected “1616” from the list. After much main and anger that they didn’t have the batteries that I wanted, I found the “CR1616” option as well. Grrr.
My Texas Instruments MSP-FET430UIF, and the EZ430-F2013 I ordered for robotics arrived on saturday. I plugged them into my laptop, and to my dismay, they didn’t immediately work. However, after a little work they both work properly. The programming speed I get now with the UIF is 12 Kbytes/sec, around seven hundred times faster than I was getting with the parallel adapter!
It just happened. There is a PCB that was generated from the parts of some laser printers!
I think I’m going to go absolutely insane with joy. Maybe after some sleep.
This is possibly the most informative post I’ve found on the mspgcc-users mailing list so far. It’s possibly amazing. I should be able to use either the UIF or EZ430 tool that TI sell.
I’ve just read a variable resistor’s datasheet claiming is has a resolution that is “essentially infinite”. Perhaps we can somehow use this device to break Heisenberg’s uncertainty principle and perform some other sorts of witchcraft.
Hello! I am writing this post over a serial line. This is no ordinary serial line. I’m in the garage on my laptop. My laptop is connected to a USB-to-serial device. That device is then connected to an xBee zigbee module. I’ve got a very similar setup on my PC in my room. The zigbee transceiver on my laptop is just out of range of the transceiver on my PC. There is a third xBee module sitting in our lounge. It has it’s receive line connected to it’s transmit line.
I’ve then got a slip connection running over that serial connection, which is 9600 bps. It’s also incredibly latent:
[rob@prefect ~]$ ping -c 5 192.168.2.1 PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data. 64 bytes from 192.168.2.1: icmp_seq=1 ttl=64 time=596 ms 64 bytes from 192.168.2.1: icmp_seq=2 ttl=64 time=596 ms 64 bytes from 192.168.2.1: icmp_seq=3 ttl=64 time=598 ms 64 bytes from 192.168.2.1: icmp_seq=4 ttl=64 time=595 ms 64 bytes from 192.168.2.1: icmp_seq=5 ttl=64 time=596 ms --- 192.168.2.1 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4000ms rtt min/avg/max/mdev = 595.813/596.868/598.809/1.156 ms [rob@prefect ~]$
These xBee modules are cool!
Apparently my MSP430 programming arrangement is only twice the speed of a 1930s telex system.
- Handed in my project progress report today! I’m glad it’s finally in! Now I can get on with doing some actual work… after writing a management essay…. and doing some exams of course.
- Started some musing about using GStreamer to simulate error correction codes and using them over lossy transmission lines. Mind debating whether the addition of GStreamer is really necessary. It would be kind of cool to put some video/audio over the error corrected lossy line.
- Got slightly more annoyed that I can’t set my default GNOME editor to be emacs (without setting it for everyone on the system)
- Need something to supercede Latex as a document editing system. Compiling the document to see a small change is too slow.
- Been learning how to get my bluetooth headset to work with my laptop. The bluetooth-alsa stuff looks like it has been in a state of flux for quite a while. It seems to be homing in on something good though. My headset almost works with the latest stuff. Apparently I need to use the latest (i.e. git) Linux bluetooth stuff along with the latest (bitkeeper i think) bluez stuff to get it working. At the moment, when I attempt to play something to the headset it successfully creates a connection (indicated by the headset’s magic beep) but then the software gives up complaining about some function returning zero (this was with a very very slightly patched 2.6.19.2). Anyway, looks promising :-) Should be fantastic when mixed with telepathy and gossip.
- My LPC2418 development module was shipped the other day. Now I’ve got to wait around a month until I get it.
Interesting links du jour:
- KVM Gets paravirtualisation – Moderately exciting. Makes me want to run rawhide even more in KVM.
- EU Commission Study Finds You’ll Save Money Switching to FOSS – Yay.
