Note: It's OK that the jtag2updi.ino file is empty as the actual code resides in the other files.Ģ. Unzip the attached 'SpenceKonde - jtag2updi.zip' file into your Arduino program folder and program the Arduino Nano. Step 1: Setting up the Arduino as a programmerġ. The UPDI/RESET, VCC and GND pins have there own separate header so that a programmer can be connected to the board even when the adapter has been soldered into another PCB.Ĭonnecting the Arduino NANO to the UPDI/RESET pin The 0.3in width was important so that the adapter can plug into a standard 14pin IC socket. I did this on purpose so I could use a single sided PCB and keep the 0.3in width. Note: The DIL pin layout differs from the SMD pin layout. The Eagle files have been included should you wish to get the adapter board commercially made or you can make it yourself. I have made a simple adapter board that allows a ATtiny1614 chip to be used as standard Dual-In-Line (DIL) device. This makes it hard to use on a breadboard. One of the problems with experimenting with these new chips are that they only come as Surface Mount Devices (SMD). The ATtiny1614 that I will be looking at has 16K Flash Memory and 2K RAM in a 14-pin SOIC package. They even compete with the more expensive and larger ATmega range of chips. Now a new series of ATtiny chips are available with more memory and functionality. Unfortunately, they had limited Flash (usually no more than 8K) and even more limited RAM (usually less than 1K). These chips powered small systems like the Digispark series. You may be familiar with the ATtiny series of microprocessors from Microchip such as the ATtiny85 or ATtiny2313.
