Having looked at it, this is the only real change and code and examples written for Atmel Studio will work fine in Microchip Studio. Solutions and Projects are identical.

The only difference is new download links and having to search for Microchip Studio not Atmel Studio.

Comment on Can I Get a Genuine Atmel AVRISP MKII? by Kanda Admin https://www.kanda.com/blog/microcontrollers/avr-microcontrollers/genuine-atmel-avrisp-mkii/#comment-2293 Mon, 21 Nov 2016 15:39:06 +0000 https://www.kanda.com/blog/?p=1085#comment-2293 Whether you have a genuine Atmel AVRISP MKII or a clone, there are issues with the latest Atmel Studio , build 1188. The firmware updater will fail when trying to update to firmware version v1.18. This leaves it broken.

The only way to recover the unit is to roll back to a previous version of Studio and do the firmware upgrade it that instead. When you roll back, you need to get rid of all the Jungo drivers as well.

We know that build 594 works properly but haven’t tried the ones in between. This Atmel Studio version can be found here:

Apart from some new device support, I can’t see the point of Atmel Studio 7 or solutions etc. Bloatware is all it is.

Needless to say that what ever I could get to run was still far slower than my old XP and Studio4.

Thank goodness for Mac reflect. It images my drive (and it includes Ubuntu) and I now do this before I install any new software. That way if it crashes I can recover in 10 minutes. It will work on a WD Passport external drive.

Bottom line is I have reverted to Win7 and AVRStudio 4 for the new laptop.

I too had problems with 19 so I stuck with 18.

As time goes on, Ubuntu is looking better and better.

Comment on AVR Microcontroller Default Clock by Kanda Admin https://www.kanda.com/blog/microcontrollers/avr-microcontrollers/avr-microcontroller-default-clock/#comment-2209 Mon, 05 Oct 2015 11:05:11 +0000 http://www.kanda.com/blog/?p=58#comment-2209 In reply to george.

CKDIV8 does exactly what is says. If you select, for example, a 1MHz Internal clock, then if CKDIV8 is set you will get 1MHz / 8 = 128KHz.
So you could select a 128KHz clock that way.

Most programmers struggle at this frequency but you don’t say which one you are using. I would guess AVRISP-MKII but not sure. Set the ISP clock as low as it will go and try again. It is often better to try reprogramming fuse back to a faster speed before trying other programming operations.

I am using ATtiny44a and I want to set 128 kHz low power internal oscillator. I went through the device programming window and set the fuse bits SUT_CKSEL to WDOSC_128KHZ_6CK_14CK_64MS. In other words, I have set the system clock to be at 128kHz, 6 cycles start up time from power-down and 14 cycles + 64 ms additional delay from reset. I have unprogrammed the CKDIV8 as well as id doesn’t make any sense. I set the ISP clock frequency to 32 kHz which is 1/4 of the system frequency but it fails to enter to programming mode. I then use little lower at 25 kHz and is able to read the device signature but still is unable to be programmed returning a message that reads 0xcc instead of 0x00.

Any help will be appreciated
Thank you

Comment on Copying Serial EEPROMs by Kanda Admin https://www.kanda.com/blog/programming/copying-serial-eeproms/#comment-2009 Wed, 26 Aug 2015 15:26:23 +0000 http://www.kanda.com/blog/?p=62#comment-2009 In reply to william ankomah.

It depends what EEPROMs they are. Wellon VP-290 Programmer has an auto-detect function so could probably determine the chip type. If they are in DIP package, you could just unsolder them and put them in socket. Otherwise, you may need a socket converter.
