While I was searching for a way to dump an entire I2C EEPROM and save it as a binary file on the PC, I stumbled on the original work, mentioned above, for SPI EEPROMs.

This is a simple library without too many extra function so you can read and write to the 25XXYYY series of Microchip SPI EEProm chips. This is developed to work with the 25LC512 you may need to do ...

Arduino UNO R4 では、これまでの8bitのATmega328から、32bitのArm Cortex-M4プロセッサへと、大幅なCPU性能の向上が図られました。ルネサス製RA4M1という日本のメーカーのCPUが採用されたという点でも喜ばしいことです。 今回は、Arduino UNO R4に1.5inch OLEDモジュール (waveshare製)をSPI接続して、デモ用の ...

Learn how to initialize and manage EEPROM settings on Arduino to store data like user preferences, calibration values, or configuration settings — even after power off! This trick helps make ...

We’ve seen projects test the lifespan of an EEPROM before, but these projects have only tested discrete EEPROM chips. [John] at tronixstuff had a different idea and set out to test the intern… ...
