Is it possible to print a custom object by passing it to Serial.print()?

I googled about it, but can't find the answer. As I would guess I would have to inherit from the Print class and somehow pass to its print methods the part of my object I would like to be printed. But I am not sure how to go about it or if it is…

Detect if Serial1 and Serial2 are defined, at compile time

I have my library that uses Serial, Serial1 and Serial2 to establish various logging scenarios. Library user would define the config at class constructor, using simple byte constants like 0, 1 and 2. Problem is, Serial1 and Serial2 are not available…

Arduino Digital Input Causing Output Problems

I am working on a simple project using an Arduino Mega 2560 that involves reading a 12-bit binary encoder signal and which is used to cycle a digital pin high and low (depending on the angular location of the encoder). My problem is that when the…

How do I transfer more than 1 byte at once via SPI bus?

I have an AD5685R DAC that I am trying to communicate with over SPI. Per the datasheet, ...These [24] bits are transferred to the input register on the 24 falling edges of SCLK and are updated on the rising edge of /SYNC where /SYNC is used as…

Why was the Atmega16U2 used on the Arduino UNO as a USB to Serial converter?

This is the first time that I realized that extra SMD IC near the USB port of the Arduino UNO is actually a fully fledged microcontroller, I thought that it was just a USB to Serial converter. Further research into this chip left me with more…

How can Arduino's 8 bit Microcontrollers handle C++

I have just started getting into Arduino and c++ programming! For all the talk on the internet about c++ being incompatible with 8-bit and even 16-bit microcontrollers, how is it that Arduino Microcontrollers can safely handle c++ code, in terms of…

How to get the firmware (hex) file from a .ino file containing the code

I currently have a .ino firmware file that I use in the Arduino IDE to program an ATmega328 micro-controller. I would like to get the file that the Arduino IDE uses to program the micro-controller. Probably the IDE uses a hexadecimal (hex) file or…

How important is the INT pin of the MPU6050 (GY-521)?

I want to wire multiple MPU6050 (at least 16 of them) to an arduino UNO for development (then nano for production). So I first started wiring one MPU6050 to an arduino like shown on the diyhacking website or in the picture below: as you can see in…
