DEP function development on a low budget48 (4/26/2013 9:35:33 AM) comp.arch.fpga Is it at all practical for home-builders on a very limited budget to develop
DSP type functions, such as filters and the like, on FPGAs? Reading around,
I get the impression that experimenters that do it ha... Bruce
Looking for ARM system with RTOS3031 (1/1/2013 1:54:30 AM) comp.arch.embedded I'm right at the end of my tether in trying to move some real time stuff
(MIDI) to Linux. The ARM-9 platform I've chosen, while very nice in other
ways, uses a proprietary FPGA interface for all the port in... Bruce
Embedded linux and achievable timer rate542 (10/20/2012 9:56:26 AM) comp.arch.embedded I've been stopped dead by a limitation with the ARM-9 250 MHz SBCs, running
Linux, that I've been relying on for my next project. The maximum rate I can
run a repeat timer (setitimer, etc) at is 50Hz, ie. 2... Bruce
Somewhat OT: Efficient timing under Linux535 (10/1/2012 5:07:20 AM) comp.arch.embedded Programming a somewhat compute-intensive and time-critical application on an
embedded ARM-9 system, running Linux. I need a clock in the low tens of
milliseconds for triggering synchronous functions, ie.

How does MidiOx handle garbage data?037 (9/8/2012 5:44:28 AM) comp.music.midi I have a misbehaving MIDI driver (my own hardware and software), and I need
to see what it's outputting to the MIDI port. At this stage I can't
guarantee that my system will be outputting a 'proper' MIDI fram... Bruce
Another midi file requirement434 (5/1/2012 6:24:22 AM) comp.music.midi Hi, I'm looking for some source code that will 'extract' just the note events from a MIDI file, all that I need is ND/NU, note no, velocity down and a time reference that can be either absolute or relative. T... Bruce
Re: Formatting SD cards under Linux142 (4/15/2012 2:48:49 AM) comp.arch.embedded Apologies to the kind people that have been staying with me on the SD card problem for not reverting to queries and suggestions. The problem isn't solved, but is definitely on the back burner at the moment, d... Bruce

High end vs low end platforms536 (3/14/2012 9:11:02 AM) comp.arch.embedded This is a serious enquiry, sorry if it comes across as a bit of a rant. I�ve done two projects over the last 6 months, both with a similar target end result, a real time device for processing MIDI messages f... Bruce
Interfacing 3.3V SPI devices to a 5V MCU1219 (2/7/2013 1:53:26 PM) comp.arch.embedded I'm about to do some work with interfacing 3.3V SPI based devices to
5V MCUs and unlike the devices I've been used to, these particular
3.3V SPI devices are _not_ 5V tolerant.
Interfacing the SPI output li... clubley(1184)

baud rate autodetection on AVR 8-bit?7035 (12/7/2012 2:17:16 PM) comp.arch.embedded BTW, is there an easy way to autodetect the baud rate while

ATmega8, given that those MCU's are such a cheap thing
nowadays.)
There're some i... oneingray(254)
