How to download data into the PICAXE 18m2 ? Answered

How to download date into the PICAXE 18m2 ?
im really confused over this.

the products i have :  picaxe 18m2, uln2803a( not sure if this is necessary), chi030 project board, AXE027 cable, and 3 AA batter power supply. i basically have the demo kit.

i was wondering if you could use this kit to download the date from the PICAXE programming editor to the picaxe18m2 or do you have to build a separate download circuit to accomplish this ? if someone can clear my confusion. im also confused about the USB Download Circuit and Serial Download Circuit and their difference.

if someone can make a small guide using pictures or video  and maybe even do the demo led test off the picaxe manual, (http://www.picaxe.com/docs/picaxe_manual1.pdf) i would greatly appreciate it. thank you


All you need is the USB cable interface and the battery power pack.

READ through the manuals - Manual 1 particularly which covers your problems in detail.

Short answer - Connect battery

Connect USB cable to demo board and to the, PC run the Picaxe editor software (free from their site) - The editod will detect the Picaxe and your program will download.

its giving me the

Error - Hardware not found on COM3:

Possible causes:
1) Hardware not connected.
2) Hardware not powered.
4) Hardware needs reset.

i have checked all this, retried it over 50 times..:(

1. You would be FAR better off posting your questions in the very friendly Picaxe forum http://www.picaxeforum.co.uk/forum.php

2. It is more likely the way your PC is dealing with the configuration.

in my experience this is caused by:
1. No power to the picaxe
2. Dead or low batteries
3. Plugged into the com 2 port, or Com 1 port or other
4. The com port being hijacked by other devices. - See in device manager what it is connected to.

other than that I promise you the downloading of programs is very very reliable - having used it 1000's of times in a school environment where Kids will find the most obscure way to prevent things working.

i used this circuit drawing


and got it to download the data in but the led is not flashing ( working on fixing the problem currently)
