Hi Rando,

It sounds like the 1.0.x system needs a slight tweak, thanks for reporting it.

If you install a zip of Arduino 1.5.5 I think it will work because in 1.5.x we read all of the programmer settings from the Arduino config where as for  1.0.x it is hard coded.

Having said, because you are using a custom 1.0.x tiny core it might be a bit messy but vm might handle it ok

I'll let you know if I see a quicke temp fix

Hi!,

Thanks for the consideration of your prompt reply.

-B bitclock

    Specify the bit clock period for the JTAG interface or the ISP clock (JTAG ICE only). The value is a floating-point number in microseconds. The default value of the JTAG ICE results in about 1 microsecond bit clock period, suitable for target MCUs running at 4 MHz clock and above. Unlike certain parameters in the STK500, the JTAG ICE resets all its parameters to default values when the programming software signs off from the ICE, so for MCUs running at lower clock speeds, this parameter must be specified on the command-line. It can also be set in the configuration file by using the ’default_bitclock’ keyword.

Let me do some testing tomorrow and get back with you.

Best,

R.

Here's a capture of a working command line sequence from the Arduino IDE 1.05r2

C:\Program Files (x86)\Arduino\hardware/tools/avr/bin/avrdude -CC:\Program Files (x86)\Arduino\hardware/tools/avr/etc/avrdude.conf -v -v -v -v -pattiny13 -cusbasp -Pusb Blinky_13a.cpp.hex:i 

Nothing magical there, total head scratch for me

I'm wondering if the solution lies comparing this what you posted? Is there a magic switch I can throw in MV to see what args are passed to avrdude. I'm not seeing the -b switch as relevant, sorry my bad.

R.

Tim,

That's a good call, when they work they work very well, and you can't beat the price... I did have to try several models before I stumbled on one that worked well with AVRdude, Bascom, etc.

R.

Tim,

Wondering how your experience with the USBASP programmer worked out. 

Just an FYI, I upgraded my Atmel Studio 6.1, just aux. packages like the AVR compiler for 8 bit controllers and had to reinstall Visual Micro for Atmel Studio, the new April combo installer did not work...

R.

Rando, what do you mean by did not work?

Did it raise an error?

Did the installer complete but visual micro did not show in atmel studio?

More info appreciated

Thanks
