Creating Libraries and Classes – Part I

This post is part 1 of a crash course on libraries and classes. It is designed to help you get started with this complex topic.

nRF24L01 – 2.4 GHz radio modules

Using the nRF24L01 and the RF24 library, you can exchange data between microcontrollers via 2.4 GHz radio. I show how it works.

4-channel, 24-bit ADC ADS1220

I introduce the ADS1220 4-channel, 24-bit A/D converter and my associated library using several example sketches.

MCP23x1y Port Expander

I compare the members of the MCP23x1y family: MCP23016, MCP23017, MCP23S17, MCP23018, MCP23S18 and show how to control them.

EEPROM Part 2 – external I2C EEPROMs

I show how you can use I2C controlled EEPROM ICs with your microcontroller. This works very comfortably with a library, but it can also be done without it.

Logic Analyzer

The Logic Analyzer is a low-cost tool that allows you to analyze signals such as I2C, SPI, PWM and much more. I introduce the Analyzer and the Logic 2 software.
