 Posted: Mon Jun 20, 2011 10:41 am Post subject: USB programmer supported by BASCOM |
 |
|
Hi all,
For the last few years, I've used a homemade STK200/STK300 programmer from a parallel port using a 74LS244 IC.
This has worked well, but with new computers (laptops) not having a parallel port I now need a programmer with a USB interface.
If anyone had a good experience with one, could they let us know the name of it, and preferably a link to a seller?
A unenclosed loaded board is fine - I can put it into a box OK. I just need to connect the AVR (SCK/MISO/MOSI/RST lines) to the PC.
TIA |

In the MCS on line shop you can find the USB-ISP and the Kamprog. Both are USB programmers.
If you want to get an mkII , i would recommend the original atmel AVRISP-MKII.
It works with ISP and PDI mode.
The clones often require special firmware when using LIBUSB. The one from atmel does not need that. It works with studio and bascom/libusb.

I'll try the one that Tubeampman suggested first - I don't know how they can sell them this cheap ($9 Australian including postage from China!)
If it works I'll buy a couple of spares, if it doesn't I'll look at the other suggestions.
Thanks to all that replied. |

|
|
We bought 2 pieces of Kamprog.
It seems that its writing data to the Atmega8. But when its finished i get the notification that the flash was programmed incorectly.
Anybody an idea about what i have may forgotten?
When i want to start the kamprog progarmmer tool by Bascom i get the error hclib and nr 126. |

are the port pins used to program the chip (miso,mosi,clock) connected to a load?
is the chip identified correctly?
I assume you use the Kamprog software, downloaded from the link?
The kamprog programmer in bascom will only work when the Kamprog software is installed.
Have a look in the kamprog software folder to see if there is a file named kavrlib.dll

I switched from the Sample Electronics Programmer to the KamProg.
I am using the same projectboard. Using the Sample programer still works.
I checked Miso, mosi and clk connections.
With the kamprog software i can read and write the fusebits.
Recognising the chip identy is also no problem. so there is communication in 2 directions.
Maybe there is a software problem in version 1.4 of the kamprog?
When i write a hex file the progressbar goes slow and steady during the programming.
When i want to verify if riten code is ok, the statusbar finishes within a blink and after a few seconds i receivedthe message that writing into flash was incorrectly.
Then i tried to read from my Atmel and to write it back in a hexfile.
The hexfile i wanted to write and the hexfile i did read back ar e not of the same size.
Maybe this information can help to see where the problem might be? |

Do you have the option 'Erase chip' checked?
I use 1.40 version too. Never had a problem.
If you have 'erase chip' checked i will test it with a M8

Hi Mark,
I used received the hint from Kamami to check the VCC on the IDC connector.
I was using the Sample Programmer in the past and never did use the VCC.
I exspected that the VCC on the IDC connector of the KamProg was an output.
But obviously i needs the vcc of my Atmel to be connected to the VCC of the IDC connector.
Problems solved.
Best regards,
Jos Clarisse |

Hi
yes VCC must be supplied by the board. this way you can also program chips with 3V.
Sample Electronics used the VCC from the LPT port.
and yes i use 1.40 version too.
I use kamprog and usb-isp.
