My Arduino and ESP are connected to reset each other when needed (via transistors to prevent accidental reset when Arduino reboots). But my SPI pins are taken up by the SD card. True I could connect ...

Connecting an SD card module to Arduino is way easier than you think. In this guide, we’ll break down the module’s pins and components, show you how to wire it to your Arduino, and get you reading and ...

I'm trying to use SPI on pins other than the default settings. I found that I cannot use any combination of the available pins, and reception of data over SPI does not work all the time. I want to use ...

In fact, transaction support in the Arduino library is something [Paul] worked on himself, and gets around the problem of having SPI-related code happening in both the main loop of a program and ...

Arduino enthusiasts or those looking to learn more about programming with Arduino and electronics-in-general may be interested in a new Kickstarter campaign and Arduino compatible 42-Digit SPI ...

In some of my projects, I use the Raspberry PICO (RP2040 or RP2350) with the TFT_SPI color display ILI9341 or ILI9488 / ST7735. They are cheap, and are available with Touch-Screen and SD-Card Slot.

MKR WAN 1310 Arduino LoRa board comes with lower power consumption, a 2MB SPI flash for OTA features, and a crypto chip for hardware security.
