ATtiny85: Power consumption vs clock speed

Short and simple: What is the power consumption for an ATtiny85 running at 1 MHz and 8 MHz using the internal clock? Not using any sleep modes. I have googled a lot and can't find any info on this. I ask because I want to know if it is worth using 1…

When using Arduino Uno as ISP does "Yikes! Invalid device signature" mean a bad connection, bad config, or bad version of avrdude?

I'm using an Arduino UNO to program a pre-compiled hex image to an ATTINY45, using the avrdude in the Arduino IDE directory, on Windows 7. The Uno has the ISP sketch loaded from the examples directory and that works- the heartbeat LED pulses…

_delay_ms() is much slower than expected (by a factor of 6) on TinyAVR 0/1 (ATTiny1604)

I designed a custom AVR development board using the Atmel ATTiny1604 microcontroller. It belongs to the new Tiny-0 family, due to its recentness, some required changes to relevant toolchains have yet to be included into the stable version (I prefer…

Emulating 1-wire device(s)

What I want to do is make a ATTiny IC become a slave on the 1-wire bus, with its own S/N and command list for its specific functions. What I want to know is if I can use the one wire library from the arduino site to send data as a slave. For…

ATtiny85. How do I burn a bootloader? What is the process?

I want to use all six I/O pins of an ATtiny85, that means also using the reset pin as an I/O pin, however, I found out that if I disable the RESET pin, I can no longer program the ATtiny using an ISP programmer. However, I found out that there are…

Manchester Library Won't Compile for Attiny85

I am creating a wireless sensor using an Attiny85. I want to send the data to an arduino uno, so I purchased the 315mhz rf link kit from spark fun. Since the Attiny85 does not have a TX I decided to use the Manchester library however it won't…

Optimizing code for ATtiny10

I'm trying to squeeze code onto an ATtiny10, but I'm just not getting there. I'm using 1060 bytes and only have space for 1024 bytes. The code is simple enough; I need to read a button pin. If high it needs to pick a random value and that causes one…

How to deep sleep ATtiny/ATmega (to run for years with batteries) but still detect a button press?

Question (TL;DR): what is the optimal method to deep sleep (to run an ATtiny45 or ATmega on batteries for 1+ year) but still be able to detect a button press? Is it possible to deep sleep until a button is pressed? I'm using a classic "debounce"…

ATtiny85 minimum setup to blink led

What would be the (very) minimum schematic to make a ATtiny85 blink a led? Restrictions are: There must be a C program compiled and uploaded to it, just like an Arduino board would have. The code would use a simple "delay" to wait a little bit…

Is it possible to program an Attiny85 with a USB-to-TTL converter?

I currently use my Arduino to program Attiny85. As I have one of these USB-to-TTL adapters I am wondering if it is possible to program Attiny85 with it, to free up my Arduino. I know it is possible to program Atmega's with such a thing. If it is in…
