    08m as a i2c slave tutorial out there?

    I'd like to make a few ADC that can talk via I2C, and maybe have a couple to drive servos. the tutorials i see are all for making the picaxe a master, but i am looking to make a bunch of slaves. anyone know of some good tutorials outs there?

    loading code FROM a picaxe

    I have a 14m that has been sitting around and I forgot what code was uploaded to it. computer that had the code was donated and is no longer findable. I dont see an option in the picaxe editor to load code picaxe, just download into the picaxe. any help, or am I back at step one?

    multiple servos on a 14m problem

    got more servos in! got em screwed to the breadboard and wired them up, used a 6v lantern battery for their voltage, using the picaxe 14m starter kit with 3 1.5v batteries for the rest. I have 5 servos tied to the outputs 1-5 then wrote a little program to twiddle them one at a time. servos...

    a question that came up the other evening

    as time marches on, so does technology, and the question for today is....... how does the picaxe compare in power to personal computers of yesteryear? I mean, the 08M certainly must be a bit more beefier than say the 4004 chip that ran old homebrew computers(altair and such) and then we have...

    GPS NMEA serin code, is this a bug?

    complicated math question

    I could test it on the simulator, but I dont think I could come up with a confident test for it. how does that math work on a picaxe? say I want to do this compassheading=((compassreading/255)*36)+37-goaldirection but not compassheading=(compassreading/(255*36))+37-goaldirection ok? i...

    pseudo code for guidance on 14m

    i've been searching the posts and am cobbling up a program that probably has been done already. please note that I dont have all the hardware ready yet, so I havent tested to see if it'll work. I just want to see if I am on the right track here. my plan is for this program to control a parafoil...

    running servos and PICaxe off same power supply?

    I really want the project I am working on to have only one power supply, a 12v gell cell. the manual says that running hobby servo motors can cause issues. couldnt I stick some large filter caps to eliminate the noise?

    what to start building before my picaxe arrives

    I plan on using a wall wart so I guess a 7805 regulator circuit. my own download circuit since i'll be making my own cable. will I need the darlington pack for driving hobby servos? stock up on 330, 10k resistors and LEDs. anything else to shop for?

    picaxe pinout compatibility

    displaying data from the picaxe from the editor?

    is there a way to display a message from the picaxe to the editor? sorat like sending a status message to the lcd but not as clunky (like basic stamps debug command) I just want it to be able to read off a variable, or give me a go-nogo status. technicaly the simulator should be able to tell me...

    which microcontroller to use?

    I've cut and pasted this a bit from the parallax forum(forgive any mis-edits), but the reasoning is the same, and it looks like picaxe is a cheaper route, but maybe not an easier one...... ok, I've decided not to go the foxhunting route, but find a garmin etrex and give it a target for...
