Breadboard Basics II (Add PICAXE)
- CPU: Picaxe 28x1
- Power source: 5V
- Target environment: Newbies with some skills
Time to add PICAXE to the board.
This requires:
- A breadboard
- 5volt power source
- PICAXE 28x1 chip
- Stereo Socket
- USB or Seriel Transfer cable
- 4k7 ohm resistor
- 330 ohm resistor
- LED
- Wire
I'm not going to go into detail about how to hook things up. If you are having problems and the images aren't helping I will answer questions if I can :) Basically all this did was help me to learn how to hook up the chip and a stereo socket to a breadboard and get basic output (blinking LED). Hopefully it will help someone else too! Lots of pics to follow so you can see how it is connected. The code follows the pictures.
For help on how to hook up the stereo socket or for what pins do what on the chip click here.
Symbol LED = 0
AGAIN:
HIGH LED
pause 1000
LOW LED
pause 1000
GOTO AGAIN
END
The code assumes you are using output 0 for the LED. If you can't get the editor to connect to your chip make sure you have the com port setting correct.
- Click START (lower left corner of your screen)
- Right click My Computer
- Click Properties
- Click Hardware Tab
- Click Device Manager Button
- Expand the Ports (COM & LPT)
- It should have an item called AXE027 PICAXE USB (COMX) X is your COM Port Number
- In the editor go to View->Options
- Click Seriel Port tab
- Select the Com Port you found in step 7 and click OK
- Try to transfer the code again.
- If it still doesn't work make sure your batteries are charged and connected to the breadboard.
- If it STILL doesn't work take a picture that shows the connections and post

nice, just a advice.. when u
nice, just a advice.. when u put a connection in the breadboard, use the most away from the components.. normaly most close to the power lines of the breadboard.. that way you can easy replace components, count the number of the pins, and test the pins signals with a multimeter.
did you understud me?! GL with your projects =)
Cool!
Nice work. Does the Picaxe
Nice work. Does the Picaxe not need an external resonator or oscillator crystal? I've been interested in this kind of thing, finding the minimum number of components you need for a microcontroller, to shrink it down once you're building you project. But at least with the Arduino, it looks like you always need at least a voltage regulator for power and resonator or crystal to tell it how fast to run. I guess maybe the Picaxe has that internally?

I'm assuming no because I
I'm assuming no because I didn't use any. My assumption is that it is internal. I guess it is smart enough to run its own clock cycles. Someone with more knowledge would have to chime in.

Some Picaxes do, some Picaxes have their own swing :)
There are 3 "ranges", depending on the chosen chip:
That's it!

PICAXE is based on PIC from
PICAXE is based on PIC from Microchip which still needs 4.8 or 5 volts to operate. If 5V power source is not directly availble then a voltage regulator is needed. I wish that Sketch and Arduino can have an option to use internal OSC and other clock values than fixed at 16Mhz. That would be nice. Definitely using Atmega 168 without Sketch you can set to use internal clock option but it must be developped using the straight compiler and load the code outside Sketch. Sketch is a nice envirnoment that eliminates these separate tools and it also has many handy libraries.
