For me the ATtiny is a perfect Co-Controller for the ESP8266 wifi chip and low current applications. You can power down the ESP, the ATtiny messures sensors, keep variable and uptime. After wakeup or trigger the ATtiny send it’s data to the ESP. The ATtiny itself going to sleep for small intervalls. Best regards, Robert The Attiny85 is a fun processor because despite being so small, it has 8K of flash, and 5 I/O pins, including analog inputs and PWM 'analog' outputs. We designed a USB bootloader so you can plug it into any computer and reprogram it over a USB port just like an Arduino. Once I receive them, I can try running some standalone ATTiny85 wireless tests, starting with running the example code you referenced above from the TMRh2O library. As I'm a brand new arrival, I don't yet know anything about the mysensors code, and I have no experience by which to judge what's normal or atypical mysensors program behavior. This tutorial will demonstrate how to build a programmer that can directly flash Atmel’s ATtiny range of microcontrollers, using only an Arduino Nano and a few additional parts. The programmer will work unmodified with the ATtiny44, ATtiny24 and ATtiny84, and is easy to adapt to the ATTiny25/45/85 by reconfiguring the breadboard wiring. An ATTiny (45/85) combined with a 74HC595 and 8 leds plus voltage regulator. This is just a simple experiment. Basically, I wanted to manage 8 different LEDs with an ATTiny and for this I need a shift register. I also want to connect a 9 volt battery to the project so a 5V voltage regulator is needed. Furthermore, 8 leds and 8 resistors are needed. Jan 05, 2017 · I’m going to use ATtiny84 as an example here. The general idea should work for most ATtiny cores.

For example, for port D, these registers are referred to in C-language by PORTD, PIND, and DDRD. For port B, these would be PORTB, PINB, and DDRB, etc. In C-language, PORTD is really a macro, which refers to a number that is the address of the register in the AVR, but it is much easier to remember PORTD than some arbitray hexadecimal number.
