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.

Now we have made it easy to add this simple operation to your ATE system.Continue reading “How to use Kanda standalone programmer for ATE” »
AVR High Voltage Programmer
The only way to re-enable Reset or SPIEN fuses on some older AVR chips like ATtiny13A, to allow them to be reprogrammed, is to use High Voltage programming (HVP) method. This was available on AVR Dragon, STK500 and STK600 but since these have been discontinued, there is a lack of suitable programmers.
So, what is now the best solution for AVR High Voltage Programming?Continue reading “AVR High Voltage Programmer” »
Move from Atmel Studio to MPLAB X IDE
Microchip took over Atmel some years ago and are slowly eliminating the Atmel brand. One of the major legacies from Atmel is their Atmel Studio development environment but its days may be numbered.Continue reading “Move from Atmel Studio to MPLAB X IDE” »
Kanda Programmer Giving No USB DonglE Found error
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” »
Atmel Studio now Microchip Studio
Microchip took over Atmel (who made the AVR microcontroller) a few years ago and have been slowly erasing the Atmel brand. Their latest move is to rename Atmel Studio as Microchip Studio.Continue reading “Atmel Studio now Microchip Studio” »
How to use AVRISP-MKII with AVRDUDE and Great cow basic
Atmel have stopped making AVRISP-MKII but Kanda sell a Waveshare version that is identical to the original. Atmel Studio fully supports AVRISP-MKII and it is simple to install and use with Studio but it can also be used with AVRDude and Great Cow Basic compiler.Continue reading “How to use AVRISP-MKII with AVRDUDE and Great cow basic” »

Kanda have been making kits to teach you how to write code for and program PIC microcontrollers for 25 years. These kits have had many updates as available tools and software have been updated. This post is a guide to selecting the kit you need.Continue reading “Kanda PIC training kits” »
Handheld Programmer on Android Phone
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.
AVR Programming – ISP, JTAG, TPI, PDI and UPDI
When AVR microcontrollers were first introduced in 1995, In System Programming was simple, with one programming method (Serial Programming Interface or SPI) and a recommended 5 x 2 10-pin target interface. For 10-15 years, this stayed the same except for the addition of JTAG programming on some devices and a move towards a 3 x 2 6-pin target header. In the last few years, new interfaces have sprouted like weeds, including TPI, PDI and UPDI. What do this all mean and how does it affect you?
