Basic introduction and simple engineering application of ATTINY84-20MU

ATTINY84-20MU is a compact microcontroller chip known for its versatility and low power consumption, suitable for various embedded applications. It features 8KB of flash memory, 512 bytes of EEPROM, and 512 bytes of SRAM, providing sufficient resources for small-scale projects.

Introduction:

The ATTINY84-20MU microcontroller, manufactured by Microchip Technology, is part of the AVR family. Despite its small size and low cost, it offers a wide range of features, including GPIO pins, analog inputs, timers, and communication interfaces.

Application in Simple Projects:

In a basic project, such as an LED blinking circuit, the ATTINY84-20MU can be utilized to control the blinking pattern and frequency. Let's create a simple LED blinker using this microcontroller.

Circuit Design:

To design the LED blinking circuit with ATTINY84-20MU, follow these steps:

1. Component Connection:

Connect an LED and a current-limiting resistor to one of the GPIO pins of ATTINY84-20MU, such as pin PB0. Ensure proper polarity and resistor value to prevent damage to the LED.

2. Code Development:

Write a simple firmware code to toggle the GPIO pin connected to the LED with a specific time delay. Utilize the AVR C programming language and AVR-GCC compiler for code development.

3. Programming:

Program the firmware code onto the ATTINY84-20MU using an AVR programmer, such as AVRISP or USBasp. Ensure proper fuse settings and clock configurations for the microcontroller.

4. Testing:

After programming, power up the circuit and observe the LED blinking pattern as per the firmware code. Verify the functionality and adjust the code as needed for desired behavior.

Considerations:

When designing the LED blinking circuit, consider:

- Power Supply: Provide a stable power source within the operating voltage range of ATTINY84-20MU.

- GPIO Configuration: Configure the GPIO pin as an output and ensure proper initialization in the firmware code.

- Timing Accuracy: Use appropriate delay functions to achieve the desired blinking frequency, considering the clock speed and execution time of instructions.

- Circuit Layout: Design a compact and tidy circuit layout to minimize signal interference and ensure reliable operation.

- Firmware Optimization: Optimize the firmware code for efficient use of resources and minimal power consumption, maximizing the battery life in portable applications.
