Not too much.How much is your time worth?
Fe eNothing wrong with wanting to save money Ec.
The other day I drove 30 miles to save 20p on fuel.
Is there an 'irony' smily?
With a baud rate of either 60 or 75 depending on screen refresh rate it isn't going to work with PICAXE!You can get a serial interface which takes signals from the screen. You just araldite it on in the middle.
That costs considerably more than the AXE027 and my laptop doesn't have a slot for that since the technology's getting out of date like serial ports.As an aside, I bought a PCMCIAAMI6RACVDAA (or whatever that slot is called) serial RS232 adaptor made by Brain Boxes.

Absolutely flawless and top quality , but well beyond most people's pocket money.
Again the brain boxes one is much more than the AXE027 and the e-bay ones will probably be equally useless as the one I already have.
Yes, I used to use the USB10.snip
Has anyone used the USB-to-Serial adaptor sold in Techsupplies?
Did it work on Windows 7 64-bit?Yes, I used to use the USB10.
However, for an extra £2.40 (£9.59 - £11.99)
I opted for the AXE027. (Less wires)
Its not that the technology of serial ports is going out of date, I am sure that we will have RS232 devices for many years to come.That costs considerably more than the AXE027 and my laptop doesn't have a slot for that since the technology's getting out of date like serial ports.
Yes. A genuine USB010 and other PL2303-based cables.Has anyone used the USB-to-Serial adaptor sold in Techsupplies?
I haven't personally tested it on Windows 7 64-bit but we have independent forum reports of it working on Windows 7, 32-bit and 64-bit systems.Did it work on Windows 7 64-bit?
I personally can't confirm it. It looks like a USB010, but then so do many others.Can you or a Rev-Ed employee confirm if this is the adaptor sold by Rev-Ed: http://www.rapidonline.com/Cables-Connectors/Cables/Computer/USB-to-Serial-adaptor-9-way-male/400921 as Techsupplies sells a lot of stuff from Rapid including 'high grade solrer'.
Thanks for the reply.I haven't personally tested it on Windows 7 64-bit but we have independent forum reports of it working on Windows 7, 32-bit and 64-bit systems.

I am seeing the same thing Using a Silabs CP2102 USB to TTL adapter & 74HC14 Inverter. Picaxe downloads with the CP2102 are consistently 3 times faster than with an FTDI based adapter.On my 2 computers (XP Home and Win7/32), the Prolific is consistantly 3 times faster when programming 3725 bytes into 28x1s - 20 seconds vs 1minute+. Refer to separate thread.
Where do I get one?I am seeing the same thing Using a Silabs CP2102 USB to TTL adapter & 74HC14 Inverter. Picaxe downloads with the CP2102 are consistently 3 times faster than with an FTDI based adapter.
To duplicate my setup you will need a breadboard, a 74HC14 IC, andWhere do I get one?
The camera has selectable resolutions so I'll use a lower resolution next time (640x480 or 1280x960). It's a mobile phone camera. I do have an all-in-one printer so I'll use that from now on when scanning circuit boards that don't have stuff sticking far off of them.Do you have a better camera, or
a flatbed scanner / all in one printer.
The flatbed is excellent for circuit boards.
Thanks for that but that one is an auction rather than just a sale.Current EBAY UK Item # 230647447668.
You can get the 74HC14 just about anywhere. DO NOT try to substitute a 74HCT version.
Don't use a lower resolution.The camera has selectable resolutions so I'll use a lower resolution next time (640x480 or 1280x960). It's a mobile phone camera.

No, it is a completely different make and brand.Can you or a Rev-Ed employee confirm if this is the adaptor sold by Rev-Ed: http://www.rapidonline.com/Cables-Connectors/Cables/Computer/USB-to-Serial-adaptor-9-way-male/400921
Fer crying out loud Nick, get a little positive in your thinking. The same module is offered via sale as well. Just do a little research.Thanks for that but that one is an auction rather than just a sale.If the HCT can't be used due to voltage limitations, the 4000-series ones should be useable as they can do up to 15v like RS232.
- What's wrong with the HCT version
- Can the 4069/40106 be used instead?
Thanks or that.Don't use a lower resolution.
It'll make things worse.
Plenty of light / stabilise the phone / highest possible resolution.
Then, use software to shrink the filesize.
I took your original pic,
sharpened it, then adjusted lighting, then shrank the size.

Found one here.Fer crying out loud Nick, get a little positive in your thinking. The same module is offered via sale as well. Just do a little research.
Nick,
It's there now.Please check your PM (Near top right of this page)
The driver is the same for both systems anyway. I'll try it anyway.I have windows 7 64-bit, and i use a prolific 2303 adapter. the way to do it is download the vista 32 driver. right click it > properties > compatibility > select vista. then run it an it works took me 5 minutes to figure it out, and it works like that for other programs as well.
Here is some advise from Prolific.The driver is the same for both systems anyway. I'll try it anyway.
Push a small screwdriver under the DB9 plug and prise it out enough so that it can be gripped with fingers. Then continue pulling it out. It'll be hard but the cable shouldn't break off.wow the new forum looks great! and does anyone know how to take a part one of the prolific cables
It didn't work. I reckon that the driver in my cable isn't a genuine prolific at all but just a cheap knock-off where the manufacturer has applied the Prolific USB settings to their own rubbish chip so that it runs using the Prolific drivers and they don't have to make their own drivers.I have windows 7 64-bit, and i use a prolific 2303 adapter. the way to do it is download the vista 32 driver. right click it > properties > compatibility > select vista. then run it an it works took me 5 minutes to figure it out, and it works like that for other programs as well.
And isn't properly set up yet so in documentation there are various [ARGx=Undefined]s where strings such as 'PICAXE Forum' should go.wow the new forum looks great!
Which, I think, confirms theUSB010 adapter and it worked straight away
The AXE010 uses a Prolific Chipset and driver. I have only seen the latency timer adjustment available with FTDI drivers.Eclectic sent me a free USB010 adapter and it worked straight away, so the one from Amazon clearly had a counterfeit chipset. The Amazon one also used a COB package for the I.C. so that they wouldn't have to put effort into doing the fake chip markings properly as it would look different from the real thing. Downloading the program to display the message below on a OLED took half a second with the adapter which means that this adapter is also faster than a standard computer serial port so I might be able to use the recent thread on speeding up AXE027 downloads.

I doubt that you can speed up downloads with the AXE010 any further than they are. Not unless the driver allows changing
the latency timer.
Why is download speed so important anyway ? Are we getting so impatient that an extra few seconds to download
a program onto a Picaxe is unbearable ? The speed you should be really concerned with is when using sertxd / serrxd or serin /serout,
or hserin/out after the program has downloaded.
I can't imagine more than a handful of people that would ever have the need to mass-program Picaxe Chips, since the target market is mostly educational/ hobby. Which is not to say that a Picaxe cannot be used in a commercial product. I sell several products using both Picaxe 14M and 8M. But the volume is less than 20 devices per month. It simply would not make any sense (MFG cost wise) to use a Picaxe in a true high volume product when the Picaxe can cost over 4 times more than the Identical PIC. ( PIC18F25K22 @ $2.05 US vs Picaxe 28X2@$8.76 US. - @Qty 100). For me the Picaxe shines in the areas of rapid development and proof of concept.
- I didn't mean on the Rev-Ed adaptor, I meant on a normal computer serial port. No, I can't do that as I have just checked.
- For download speed importance, some people want to mass-program PICAXE chips. Then it's important. Even so, why not? Using the slow mode would be like running a PICAXE-40X2 at 4MHZ and no-one does that!
I guess I've never had a DL speed issue since I have always used my own USB DL circuit based on the CP2102. (3 x Faster than Serial or FTDI)Download speed matters a lot to me. I don't recall much of my code ever working the first time I downloaded it, or the second, or the third....
I simply keep changing my code over and over until it works, so the download speed determines my programming speed and I spend most of my time just waiting for the download. So far, faster downloads matter more to me than faster processor clock speeds.
