Differences with standard Arduino SD library: You can choose desired SPI which SD card is connected to. In case to choose SPI you should pass the SPIClass object as the first argument to the method ...

I’m trying to use the SPI SD card example from ESP-IDF to mount a micro-SD card via an SPI SD card module. It works fine using Arduino-ESP32, but fails in ESP-IDF. Environment: IDF Version: v5.4.1. OS ...

When the clone starts up, it searches the SD card for a file called ‘program.hex.’ This file is sent over to the target Arduino and the new firmware is installed.

– May be a card for programming the firmware on your AVR project since you already bring the SPI pins to the SD connector – just need the reset line. That might actually be cool. – A gag item.

A maker developer has squeezed an Arduino onto an SD card. He was inspired by Intel’s Edison compute module and he tried to go one better. The result is the SDuino, an ATMega328P processor-based ...
