Arduino Due HTTPS Support
Unfortunately this is too long for a comment. ► No out of the box solution From what I have gathered, there is no straightforward solution for a webserver running on the Atmel SAM3X8E ARM Cortex-M3 CPU that outputs HTTPS out of the box. Texas Intstruments provides better options at the moment using their boards equipped … Read more
How can I digitalRead a pin that is in pinMode OUTPUT?
In this case you just want to access the data register itself. PORTB and PORTD registers contain the pin data you are looking for. I finally got access to an Arduino to figure it out. You want to use bitRead(PORTD, pin). Serial.println(bitRead(PORTD,3)); //Reads bit 3 of register PORTD which contains the current state (high/low) of … Read more
How to program an Arduino with C++ [closed]
Here is my experience: I’m building a robotic smart toy for autistic children using Arduino, sensors, motors, led and bluetooth. I wrote my own libraries to do exactly what I needed using C++. But I found out that the Arduino IDE Compiler is an older version that does not support the new C++11 features. So … Read more
Where are the hex files compiled by Arduino?
In the Arduino software: go to File -> Preferences and then select Show verbose output during -> compilation. Finally, when you are compiling, the program will show you lots of data. At the last lines, you will find the path1 to the .hex file. 1Every time the path changes!
Does it matter which microcontroller to use for 1st time embed system programmer?
Personally, I’d recommend an ARM Cortex-M3 based microcontroller. The higher-power ARM cores are extremely popular, and these low-power versions could very well take off in a space that is still littered with proprietary 8/16-bit cores. Here is a recent article on the subject: The ARM Cortex-M3 and the convergence of the MCU market. The Arduino … Read more
How do you debug Arduino code running on Arduino hardware?
The Visual Micro plugin for Microsoft Visual Studio 2015 Community Edition (free) provides a USB debugger for Arduino. It allows you to do exactly as you describe. (Don’t forget to click to install C++ during IDE install) The debugger supports serial, RF, Bluetooth and some Wi-Fi. It enables the values of variables to be watched … Read more
Using classes with the Arduino
On Arduino 1.0, this compiles just fine: class A { public: int x; virtual void f() { x=1; } }; class B : public A { public: int y; virtual void f() { x=2; } }; A *a; B *b; const int TEST_PIN = 10; void setup() { a=new A(); b=new B(); pinMode(TEST_PIN,OUTPUT); } void … Read more
avrdude: stk500v2_ReceiveMessage(): timeout
Another possible reason for this error for the Mega 2560 is if your code has three exclamation marks in a row. Perhaps in a recently added string. 3 bang marks in a row causes the Mega 2560 bootloader to go into Monitor mode from which it can not finish programming. “!!!” <— breaks Mega 2560 … Read more
How to find the serial port number on Mac OS X?
You can find your Arduino via Terminal with ls /dev/tty.* then you can read that serial port using the screen command, like this screen /dev/tty.[yourSerialPortName] [yourBaudRate] for example: screen /dev/tty.usbserial-A6004byf 9600
