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.

Programming the ESP32 with MicroPython

In this post, I show you how to program the ESP32 with MicroPython. I go into detail about the A/D converters, I2C, timers, RTC, touch pins, etc.

MicroPython – Switching from Arduino

This is a MicroPython crash course for people with Arduino/C++ experience. I use the ESP32 as the MCU and uPyCraft as the IDE.

Programming the ESP32 with Arduino Code

I introduce the ESP32 and its main features. In particular, I will discuss the differences to the Arduino (AVR) boards.

How to use the I2C interfaces of the ESP32

I will show you how to use the two I2C interfaces of the ESP32 and which requirements libraries of I2C components must have for this.
