Using the following variant of the Blink program I determined that the devices I got from China are the Rev 2 variant – which is good since I’m most likely to be hooking things up via I2C since there are, after all, only 6 I/O pins on this little beastie.Arduino IDE Showing List of Supported AVR Programmers with Arduino as ISP Selected Wiring the ATtiny85 to an AVR ProgrammerĬonnecting the ATtiny85 to an AVR programmer is straightforward. They have subtly different wiring regarding how the onboard LED is connected (pin 0 for Rev 1 and pin 1 for Rev 2 (and Rev 4)) and I2C compatibility (Revs 2/4 are out-of-the-box I2C compatible). Since I was only messing with the Blink program, I’m guessing that it’s early death was more due to Shenzen sweatshop quality control standards rather than a deep-seated design defect in DigiSpark itself.Īpparently there’s a Rev 1 and a Rev 2 DigiSpark.

Good thing since I killed the first one after about an hour of playing. I ordered three of the Chinese clones at once. At other times it Just Worked first time. Generally I found the programming to be a bit flaky with quite a lot of unplugging and replugging to get the program uploaded at times. I’d recommend a USB extension cable for convenience and so as to not put too many miles on your PC’s USB connectors. you can’t just leave the gadget permanently plugged in at the end of the USB cable while you make change after change – it’s slightly annoying but I can live with that. The first thing to note that’s a bit weird / different with the DigiSpark as opposed to the normal Arduino is that you need to leave the device / target normally unplugged from USB, then you press Upload on the IDE, then you plug it in, the programmer detects the device and uploads your program.

DigiSpark has its own USB interface, unlike, say Arduino Pro Mini.īootnote 2 – First Program With DigiSpark.You’d be amazed how many of your microcontroller jobs can be done with 6 I/O pins.(Sorry to the DigiSpark creators, I’d love to support you by buying from you, but in Spain we just can’t afford that luxury right now since the country is in about as good economic shape as Greece.) DigiSpark clones from China / eBay are about $2 delivered.So that’s really cool for automotive (nasty power supply that’s often at almost 15V and spikes around), machine shop (24V), and solar (18V or more on open circuit for a nominal ’12V’ panel). It’s got great power supply options with a beefy regulator that accepts up to 35V(!) input and supplies up to 500mA (presumably not when feeding with 35V since it’s an oldskool 7805 linear regulator).I say ‘motherboard’ rather than ‘shield’ here since your PCB is likely to be a fair bit larger than the DigiSpark itself. Being so tiny you can take advantage of Dirty Board PCB’s manufacturing at $14 shipped for 12 5x5cm PCBs for making ‘motherboards’ for the DigiSpark. 2.7×1.9cm and that includes the USB connector.

If you want to build this yourself (I would totally understand if you did), here’s the source to that binary.īootnote 1 – What’s So Cool About Yet Another Arduino

Install the standard Arduino IDE for 64-bit Linux.

Since it’s Open Hardware, the inevitable happens and some people in Shenzen have taken the board layouts and started cranking out the hardware super, super cheap. The DigiSpark isn’t a particularly New Thing – it was a KickStarter project from August 2012. The problem is that it doesn’t seem to play nice, out-of-the-box with 64-bit Ubuntu Linux. It’s about the size of a postage stamp, plugs straight into your USB port and will probably cover most of your microcontroller project needs. DigiSpark is one of the cutest Arduino-related widgets around.
