Hello, I'm investigating the possibility of maybe looking at the applications of perhaps doing something along the lines of this: some background: AES3 is a digital audio protocol. the long & the short of it is that it runs at 24MHz (max, dependant on audio samplerate) on a balanced signal...

Hey guys. Been a while. I was wandering if there is any way I can store an array in the scratch pad and use background serial receive. basically, I'm making a HUI Timecode readout (midi), and using background serial to receive the midi messages. The way HUI sends the timecode is actually as a...

Heya, Ive been poking around some midi implementation for a while. I want to make a midi clock that displays Bars:Beats from the midi clock. It needs to respond to Song Position Pointer, Beat Clock, and the Time Signature packet (get get beats per bar). Ive got the hardware side of it working...

Heya, I've done a bit of reading on this, and it seems like a very cool way of doing time critical processing... does anyone have any good tutorials on how to go about an RTOS, or better yet, has anyone implemented one on a PICAXE (or even, can it?) From what I understand it as, its a stack of...

Heya, I've got my hands on some 100-seg led bargraphs. they are split into 10 segments of 10 leds. anodes address the segments, cathodes address the individual leds in that segment, if that makes sense. my plan is to readadc, then output onto the bargraph doing a common anode driver is easy...

Has anyone tried these? http://multimedia.3m.com/mws/mediawebserver?66666UuZjcFSLXTtNXT2OX&6EVuQEcuZgVs6EVs6E666666-- they look like proper in-circuit programmers, eh? has rev-ed/picaxe thought about producing a version of these that has a small psu & usb cable attached? would be very nifty!

Heya, I have a reather lengthy program. its running fine, but im wandering if i can tweak it so it is more responsive, so optimising for speed here. first question (and most important): Does a 'smaller' program (ie bytes) mean it will run faster. or is it dependant on the commands used. or is...

Hello. I'm having trouble programming my 28x2 from axepad. Ive tested the serial cable (usb -> minijack) using the options for high & low, and it works fine. I can clear the hardware memory, and i can download a basic program (eg high c.0). but for whatever reason it wont download my program. it...

I was reading cooldude's post on dimming etc around the house, and the talk got into 'sine wave' dimming & all that, I didn't want to hijack his thread, but... could you use a (cheap) audio amplifier, say 100w, to drive 12v halogen lamps? they dont operate at very high output voltages (when not...

Heya, I've found some strange 'issues' with Axepad on Mac OS X 10.6 (snow leopard). Latest revision, coding for 28X2 copying & pasting seems to screw up code. it looks like it adds text between characters/commands, but keeps them hidden. So it seems like its copy & pasted correctly, except...

never mind, bad question. move on, nothing to see! thanks anyway

But i cant find it. I would like to use symbols to assign pin values on a 28x2 part symbol led1_sda = c.0 symbol led1_clk = c.1 symbol led1_cs = c.2 b1 = b0 & 1 led1_cs = 0 led1_sda = b1 led1_clk = 1 led1_clk = 0 led1_cs = 1 this returns a syntax error. it doesnt have to be on PortC...

Yes, im mad and crazy. but I have implemented a very basic PID loop to control the position of a motorized P&G fader (PGFM3200). setfreq m8 symbol kP = 40 '/20 gain of 2 symbol kD = 10 '/20 gain of 0.5 symbol correction = w0 symbol PrevErr = w1 symbol Err = w2 symbol ErrSum = w3 symbol temp =...

impartation: Vista wouldnt let me install drivers. I dont know how, or why. when i plugged in the usb cable it would say "found new hardware, searching for drivers"... I thought, brilliant... here we go. So, as there isnt a standard driver for the usb cable, it came up saying "Driver not found"...

How accurate is the vsm timing? im trying to see if its plausable to use a pic to do analogue sampling at 30hz with quite a bit of other processing going on. hippy (or another senior member) said that the adc sample time was 250 us, which suggests a possible speed of 4khz. however, just...
