Apr 29, 2016 · The newer Arduino boards (Due, Zero, 101) have no EEPROM at all, which makes them useless. It is cheap (USD $20) The power consumption is low. It works internally at 3,3V, but can be fed with 5V. The Teensy library (TeensyDuino) has more and better functionality than the offical Arduino libraries. The leds arrived last night and I plugged them into one of my cheap ESP32 devices and got it sort of working. I found an Arduino library and, after tweaking the C++ library code I manged to make it build and almost display something. Writing and deploying C++ from the Arduino IDE again reminded me why I don’t like this very much anymore.

EEPROMStore is an Arduino library to look after saving and loading data from the EEPROM. Data in the EEPROM is not lost when the device loses power, or is reset, so it is a good place for storing program configuration. A check sum is stored with your data so the library can detect an EEPROM that hasn’t been initialized, or may contain invalid ...
