Atmel, now Microchip, have been moving away from AVR ISP programming method for some time. All the latest AVR microcontrollers now use UPDI programming interface but some ATtiny chips used TPI interface, which is discussed here.Continue reading “Atmel AVR TPI Programmer Selection” »
AVR microcontrollers were first introduced almost 30 years ago and since then there have been a few changes, especially since Microchip absorbed Atmel. The AVR was one of the first microcontrollers to have onboard flash memory that could be electrically erased and reprogrammed and this enabled the introduction of In System Programming or ISP.Read more: All You Need to Know About AVR ISP, UPDI, JTAG, PDI and TPI.

Older versions of Kanda Software will not work with latest FTDI USB driver 2.12.36, released 17/06/2021. This applies to PIC and AVR handheld programmers, AVR keyfob and AVRISP-U programmers.
The solution is to roll back the driver to 2.12.28, released 16/08/2017.Continue reading “Kanda Programmer Giving No USB DonglE Found error” »
Kanda have released a free Android App, for smart phones and tablets, that lets you update your AVR or PIC handheld programmer contents from your phone. Just load the programmer, copy it to a programmer file (.PRG), send it to your customer, distributor or engineer and they use their phone or tablet to update the programmer.
Atmel have added a new feature to Atmel Studio from 6.2 on-wards including 7. You can now create a single file that contains all the data needed to program an AVR or ATxmega microcontroller. This includes flash, EEPROM, fuses, lock bits and ATxmega User Row. This is called an ELF production file and Kanda AVR Handheld Programmers now support this format.
