I'm currently working on a project using Arduino 1.0.6 IDE and it does not seem to accept C++ 11 std::array. Is it possible to change the compiler flag to make this work? Using the IDE is very difficult to do that. I would advise you to go full command line by using Sudar's great Arduino Makefile . This way you'll be able to customise the compiler flags to your liking. I've also created the Bare Arduino Project to help you get started. The documentation covers a lot points, from installing the latest avr-gcc toolchain to how to use the repository, compile and upload your code. If you find

Blue led is blinking after powering up the module, the red one stays on, I can even connect to it via wifi. But I cannot program it. I tried Arduino IDE, different firmware flashers (Like NodeMCU, XTCOM). I'm using Arduino Mega. Here's my initial setup: VCC - 3.3 V on Arduino RST - nothing CH_PD - 3.3 V on Arduino TX - RX on Arduino (TX is transmitting data to RX, so I don't need a voltage divider, right?) RX - voltage divider (R1 = 10K, R2 = 20K) - TX on Arduino GPIO0 - GND on Arduino GPIO2 - nothing GND - GND on Arduino Then I tried uploading a sketch from the Arduino IDE and got the

The Arduino docs explain yield() at https://www.arduino.cc/en/Reference/Scheduler with regards to the Due. Apparently it is part of the Scheduler library: #include <Scheduler.h> However, I can call yield() on my Nano or ESP8266 without including the Scheduler lib -- but only in my main program, not inside include files. Also, the include does not work on my non-Dues. What's the secret that I'm missing about yield() or- what does yield() do on Arduino platforms other than Due? However, I can call yield() on my Nano or ESP8266 without including the Scheduler lib The yield() function is also

I am using the ATMega328P at 11.0592MHz with the Arduino environment. I recognized that the delayMicroseconds() function is about 27% too fast. The reason is, that the code in wiring.c assumes that the clock peed is now 8MHz. Now I try to fix it. I found different posts but I am not sure what is the most Arduino compatible way. What can you recommend? Multiply the variable "us" in wiring.c with 1.27 if the F_CPU is 11.0592MHz? Easy but only affects delayMicroseconds and not millis(), micros(), delay(), etc. Change the prescale factor maybe from 64 to ??? Other ideas or guides? Thank you in

I am trying to print an integer alongside a string but it's not really working out and am getting confused. int cmdSeries = 3; Serial.println("Series : " + cmdSeries);// That's where the problem occur In visual basic we used to do it this way: Dim cmdSeries As Integer Console.Writeline(""Series : {0}", cmdSeries) So i've tried it with Serial.println but it returns this error : call of overloaded 'println(const char [14], int&)' is ambiguous Can anyone help my out, I want to achieve this without using any libraries and in a clean way. There is a huge difference between Arduino String class and
