Interrupts – Part 2: Pin Change Interrupts

Part 2 of my series about interrupts deals with pin change interrupts. These are specific for AVR based Arduino and MiniEVB boards.

MiniEVB Boards – an overview

LGT8F328P MiniEVB boards are available in different versions. I go into the differences and compare their power consumption.

LGT8F328P – LQFP32 Boards

The LGT8F328P is a microcontroller compatible with the ATmega328P, but cheaper and even more powerful. I show how to program LGT8F328P based boards in the Arduino environment.

ESP-NOW

With ESP-NOW you can easily send messages of up to 250 bytes between ESP32 and/or ESP8266 boards. A step-by-step introduction.

SRAM Management

This post is a journey into the depths of SRAM, Heap and Stack. How are variables stored there? What should be considered when using strings? Here you will find the answers.

Using megaTinyCore

Thanks to the package megaTinyCore, you can easily program the ATtinys of the tinyAVR series 0, 1 and 2 with Arduino code. I present several options for the upload of your setches.

TinyWireM vs. Wire for ATtinys

To save valuable flash memory on ATtinys when using I2C, you can use alternatives to Wire.h such as TinyWireM. I show how it works.

Programming ATtiny with Arduino code

The ATTinyCore package enables you to program a large part of the ATtiny family via the Arduino IDE. I show how this works with or without bootloader.

EEPROM Part 1 – AVR internal EEPROMs

AVR microcontrollers have an EEPROM in which you can store data permanently. I show you how to write to and read from it.

Using WiFi with the ESP8266 and ESP32

I show you step by step how to network and control your ESP32 or ESP8266 boards via WLAN and how to exchange data between them.
