* Inform slave of a master button press. * SPI pin numbers: * SCK 13 // Serial Clock. * MISO 12 // Master In Slave Out. * MOSI 11 // Master Out Slave In. * SS 10 // Slave Select * If you found this ...

This is an example test library for the Epson M-Gxxx/M-A352 Sensing Units (SU) using the SPI interface. It was specifically developed for use with the Arduino Teensy 3.6 development board (Teensyduino ...

Quick, how do you wire up an SPI bus between a microcontroller and a peripheral? SCK goes to SCK, MISO goes to MISO, and MOSI goes to MOSI, right? Yeah. You’ll need to throw in a chip select pin, but ...

Arduino has certainly made its mark in the world of DIY electronics, providing an accessible platform for a wide range of creative and interactive projects. Known for its user-friendly hardware and ...

So here’s the thing: Arduino’s built-in memory is tiny. If you’re just blinking LEDs, no problem. But the moment you try to log data, say battery usage, temperature over time, or GPS coordinates, ...

While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.
