Cortex-M3 vs PIC32 divide instruction2947 (9/6/2011 7:39:57 AM) comp.arch.embedded I've finally been considering a project to use either a Cortex-M3 or a PIC32 processor and I've a technical question unrelated to any "business issues" between these options -- the divide instruction operation....

a hobby class on microcontrollers10163 (6/27/2010 9:22:38 PM) comp.arch.embedded I need to think about a class that will include both young and old, all of whom have very little experience but at least the hope of trying to enjoy such a class on microcontrollers without knowing anything muc... Jon
Extended Hamming encode/decode72298 (3/7/2010 12:56:43 AM) comp.arch.embedded I needed to write some very simple c routines (tempted to use
assembly, but not for this application at this time) to
handle the following extended hamming code cases:
[ 8, 4, 4]
[16, 11, 4]
continued fraction program6583 (6/20/2009 9:50:33 PM) comp.arch.embedded Okay. I think I'm done playing, for now. There's a free continuous fraction program available. This program provides the convergents for the continuous fractions of a value (plus declining error terms) and i... Jon
arm7 core with fast monolithic 12-bit ADC2754 (2/11/2009 10:10:24 PM) comp.arch.embedded I'm just getting into a project which "prefers" the ARM7 for business reasons, not technical ones. I do _not_ have experience writing for the ARM7 beyond some modest playing around, but will muddle through tha... Jon
Really tiny microcontrollers5053 (2/25/2013 8:47:20 AM) comp.arch.embedded I'm wondering what the physically smallest microcontrollers are, that
aren't too crazy to program and that are amenable to hand soldering with
normal SMT tools. I've found some of the ATtiny parts in 2x2mm
Sine Lookup Table with Linear Interpolation12071 (3/16/2013 10:30:51 PM) comp.dsp I've been studying an approach to implementing a lookup table (LUT) to
implement a sine function. The two msbs of the phase define the
quadrant. I have decided that an 8 bit address for a single quadrant ... gnuarm(3046)
booting the Linux on bare metal board.1333 (3/21/2013 6:08:24 AM) comp.arch.embedded Hi guys
I was studying about the JTAG and than I all of sudden I got few questions
in my mind regarding the linux booting on the embedded hardware.
Actually I know the procedure of how the linux boots... piyushpandey
Microcross X-Tools license help?1028 (5/9/2013 11:33:11 PM) comp.arch.embedded It seems that Microcross, Warner Robins, GA a supplier of Visual X-Tools
and gnu x-tools has gone away. Web site has been down since last year.
I have used their tools on a few projects over the years and... nrm6097(7)
Simple I/O on Windows PC3824 (6/21/2013 9:13:47 AM) comp.arch.embedded Suppose I have an x86-based PC running Windows 7; I have a couple of simple
o Write a single bit to a pin somewhere (perhaps connected to an LED)
o Read a single bit from a pin (perhaps connected to... bc(2337)
The Embedded Heap3919 (6/21/2013 5:45:09 PM) comp.arch.embedded I know this is a dangerous question to ask, because often people tend to
run on emotion with this issue.
I ask, because _I_ tend to run on emotion ("hey! That guy suggested
using "new"! Where's the tor... tim177(4434)
Cortex M4 Floating Point Size2220 (7/30/2013 9:08:52 PM) comp.arch.embedded I am, apparently, incompetent at reading data sheets.
At least when they get up to several hundred pages.
Do Cortex M4 parts deal with 64-bit floating point in hardware, or just
3D printers for small run boards88 (8/31/2013 11:38:25 AM) comp.arch.embedded I have had a couple conversations in the last month about the future
of 3D printers.
One potential application that has come up is the ability to create
prototype (or small run ) circuit boards. The possib... walter20(887)
