• Pin4 (GND): Pin4 introduce ground or negative power to the system.
• Pin5 (PBO) : The main functions of Pin5 are AINO, MOSI, OC1A, OCOA, DI, AREF, SDA and PCINTO. It take charge of SPI communication, PWM output and 12C communication.
• Pin6 (PB1) : The main functions of Pin6 are MISO, AIN1,OCOB, OC1A, DO and PCINT1. Pin6 is used for PWM o/p, SPI data o/ P.
• Pin7(PB2)The main functions of Pin7 are SCK, ADC1, TOm SCL and PCINT2. Pin7 is mainly used for SCL and SCK of analog i/p and SPI data.
• Pin8 (VCC): Pin8 is used to provide voltage supply to the system.

What is the size of ATtiny85?

Recursos & Functions & Inscrição

ATTiny85 distinguish other ICs by many advantages. Primeiro, lower cost and less power consumption make it friendly to the users and environment. Segundo, due to its small and compact size, it can be easily arranged in a small Placa PCB. Terceiro, it is capable of working with battery-powered application programs by different power saving modes. A introdução de novos produtos não é um processo fácil, many functions are embraced by small pins, so it takes a full use of space when it’s used in small and high-tech PCB. Último, its program memory is not bad.

ATtiny85 is a very advanced micro-controller that includes several functions, so it can be used in a variety of electronic applications. This micro-controller just like a small Arduino. Once the code is small and alternative controller is required, then the ATtiny85 is the right choice.

It is widely applied in different fields, como automotivo, controle industrial, sensor system, solar energy device, telecomunicações, Aparelho médico, IoT, embedded system and even robot field.

What Is the Differences Between ATtiny84 and ATtiny85?

They are different in the pin configuration. ATtiny comes with 8 alfinetes. Five of them is suitable for digital I/O. Three of them can serves analog input. Two of them can be PWM pins. Em contraste, ATtiny84 has 14 alfinetes. Eight of them is available for digital output and analog input. Three is capable of PWM output. O que mais, its PB7 pins also supports PWM.

What Is the Differences Between ATtiny13A and ATtiny85?

Compared to ATtiny13A, a 85 has more flash, RAM and EEPROM memory. Além disso, Attiny85 is easier to get started than 12A since it has more libraries available.

How to Use ATtiny85 with Arduio?| After Buying

Ttiny85 ISP is an open-source device with Arduino IDE compatibility. Here we take one of using case, mini USB, to show you how ATtiny85 uses in eletrônicos de consumo.

This design uses an internal 8 MHZ clock to drive the microcontroller. To transfer data to the FTDI board, pin 2 of the microcontroller is connected to the TX pin of the FTDI board. FTDI splitter on pin 3 offer 5V-powers to the microcontroller. Jumper JP1 is used to enable/disable resetting micro-controller when establishing terminal connection with FTDI splitter board.

When debugging sketches with AVR Dragon, don’t forget to turn on jumper JP1. De outra forma, capacitor C3 will cause side effects when stepping code.

How to Program ATtiny85?

You can use Arduino Uno to program ATtiny85.

Degrau 1: We first need to configure the Arduino Uno as an ISP to act as the programmer for the ATtiny85. Para fazer isso, connect the Arduino Uno to your laptop and turn on the Arduino IDE. Então, click file >Example>ArduinolSP and upload the Arduino ISP code.

Passo 2: Program ATtiny85 circuit diagram.

Etapa 3: Program it by the Arduino IDE.

How to Run ATtiny85 Carefully?

It is a very sensitive component. To get the best performance from controllers over the long term, designers should be careful when using them in any application.

• Supply voltage should not exceed 5.5V. And the output of the voltage source needs to be verified by an accurate digital multi-meter before connecting.
• The DC of each 1/0 pin should be 40mA. The GND pin and positive power supply should be 200mA. Before power is supplied, the polarity of the micro-controller pin should be verified.
• To position this controller, you need to use an IC socket on the circuit or breadboard that protects the controller from the heat generated during welding.
• além do que, além do mais, the minimum and maximum storage temperature is -65°C to +150°C, but the operating temperature is -55°C to +125°
