Hi.
I'm writing here, because i have been reading a lot of topics, and I can't still solve my problem (Sorry for my English... I'm not native).
I have a PICAXE-28 Starter Pack with the AXE027 usb and the PIC16F886 chip
Also, I have 3 AA batteries 1.5V (non-rechargable)

All items were bought in PICAXE webstore (www.techsupplies.co.uk).

The topics that I have read are:

Well, my "issue" is: I cannot download any code to chip.

I decided attach some pictures... So, you can see what I mean.

Ohhh, almost forgot... My OS is Windows 7.

Chip = PIC16F886
Version Board = Red - Ed LTD 2001
Clip batteries test (3 AA // 1.5V) = 4.51V
Plug Test (usb port test + led ON) = 5.16V
Plug Test (usb port test + led OFF) = 0.01V

Download circuit test



Pins test (following picaxe manual instructions: "TEST ON ACTUAL CHIP V+ and 0V pins with a multimeter")
(Pin # 8 - Ground ) // (Pin # 20 - Positive)



The Picaxe manual (pdf) says:

Download Checklist

PICAXE microcontroller

• Is the correct PICAXE chip correctly inserted in socket (I think it's ok)
• Is a PICAXE chip (not blank un-programmed PIC chip) being used (I think the website would not fool me, right?).
• Is a damaged PICAXE chip being used (chip has had over-voltage o reverse power supply applied) (I think it's ok, I always use 3 AA batteries alcaline 1.5V non-rechargable)
• Is a smooth 4.5V to 5.5V DC supply correctly connected. TEST ON ACTUAL CHIP V+ and 0V pins with a multimeter! (I think it's ok, the last 2 pictures show that)
• Is the reset pin connected to V+ via 4.7k resistor (18 / 28 / 40 pin chips) (I don't know)
• Is the correct 3 pin resonator connected if required (28 / 40 pin chips) (I don't know)
• Are the serial download 10k/22k resistors correctly connected. (I don't know)

I have installed the usb controller, about two times... one from CD (.zip) and one from file of picaxe website (.exe).
I will hope that anyone can help me.

Thanks.
Jorge.

Welcome to the forum :)

I'm not that experienced with solving these issues but it does seem strange, can you do a firmware check or does that fail to?

I have to say, you dont often see that much detail put into a post around here, well done :)

I'm sure Hippy or someone will come along and spread some light on the situation,
Jamster

Hi.
When I tried to "check firmware version", I previously selected "Picaxe-28X1/40X1" option...
Then I click "check firmware version" and programming editor show "Hardware not found on Com".

So, I could say it fail (I think). :eek:

Open up 'options' and select the serial port tab.
You should see a list of ports and what is connected to them.
Does the port you are using have the AXE027 shown.
If yes, then try the 'test port' button and let us know what happens.
If no, then select the port which has the cable associated with it.

Have you tried to cold boot the picaxe?

remove power from the board.

Connect then AXE 027 cable to the PC and the board.

In porgram editor, start the download.

Connect power to the board while the download bargraph is displayed on the PC.

The test are:

Plug Test (usb port test + led OFF) = 0.01V
Download circuit test (socket of the plug 3.5mm usb cable - image attached previously) = 5.05V

Sorry, I thought it shown with picture in the main post.
Not this?

Pins test (following picaxe manual instructions: "TEST ON ACTUAL CHIP V+ and 0V pins with a multimeter")
(Pin # 8 - Ground ) // (Pin # 20 - Positive) = 4.42V

If I wrong, please let me know it.

I believe BeanieBots was asking about the Serial Port / LED test and measuring the high/low on/off voltages on the actual PICAXE chip rather than on the download socket -

(Pin # 8 - Ground ) // (Pin # 6 - Serial In)

A few additional questions -

Do you have any other PICAXE boards you can test downloads with ?

Do you have any other 28-pin PICAXE which you could try in the board ?

Do you have any other PICAXE board you can try your 28X1 in ?

I'll find how do this? because actually I don't know.
I have measured:
Usb plug (section "c" and section "b" // diagram)
Download circuit (Socket)
Pins of the PIC16F886

Questions.
1. No, I don't have other board. I would like to buy it again, but I wouldn't like to have the same "issue".
2. No, I don't have other chip.
3. No, I don't have.

I have to pleasure to show you this:

So, I think the USB cable isn't the "issue".
I´m using UBUNTU 12.10 and AXEPAD.

When I try to connect the board to PC (using usb cable AXE027)... Axepad show: "Hardware NOT found"

Next step: Serial Port / LED test!!

Excellent news, though I thought you did not have any other boards or PICAXE chips. You can test the 28X1 from the 28-pin starter pack in the AXE401 Shield Base to see if the chip works in that.

Oops.
I didn't know, that I could do this. :rolleyes:

Next step: Test picaxe 28x1 chip on AXE401 board.
I have read manuals (both of them) and the power supplies are the same 4-5V.

hi all,

I have a similar problem...I'm using an axe091 board and 2 days ago, programmed a 08m2 chip perfectly. when I started up my program yesterday, now I'm getting a "hardware not found" message.
The program is seeing my axe027 cable on com port 4 and all tests are ok, but still can't program my chip. I've tried a hard reset many times to no avail. Using brand new batteries for the board too.
Any suggestions ?
Ken

You are probably not getting the Hard Reset timing correct or not following the exact required procedure.

Or it could be you have destroyed the 08M2. Replace it with a new one and see if you can download to that.

same problem in Win 8 Pro, 64bit

I recently installed the Logicator, WinAXE and Programming Editor to work with a MicroBot (20X2 CPU). The AXE027 USB cable is detected by Windows, after installing the drivers. I checked out the 'bot with a multimeter in continuity mode, and extensively inspected all the contacts. No problems there. I've tried the tips mentioned in this thread. Keep in mind that my 'bot doesn't have a reset switch or button. It has an on/off switch, and that's the only way to reset the 'bot.

Any ideas? :confused:

Same solution.

Try a Hard Reset. Switch the power off, initiate a download, wait for "Searching for Hardware...", then turn the power back on.

Had some time to look at the robot again. I noticed that the battery box leads weren't making good contact to the motherboard. I bent them out slightly, and straightened them. The bot now works as directed! :)
