- Sun Jun 07, 2015 4:05 pm #19775 Hi.
I try servo library and compiller give me message like "sam and AVR is only supported"
I try to copy servo library from github to "hardware\esp8266\1.6.4-673-g8cd3697\libraries\Servo\"

but give me a lot of error

I try to modify source for missing files, but still servo library not work for me...
Can anybody help me?
I use Arduino 1.6.4 and install esp8266 board from boards manager... Running win7 x64

- Sun Jun 07, 2015 6:42 pm #19784 Go into Preferences and at the bottom there is a link to where the ESP libraries are . Follow it through and you will see that "servo" is not installed for the ESP8622.

So you must try with the servo library installed with the IDE and if it does not work petition igrr at github ESP8266/Arduino to include the library maybe?

Get you modules here:

but after flash bin to esp-12 it print this over serial.

What is wrong? Exist any binary of ESP arduino from last source code from git?

my sketch is :

Code: Select all#include <Servo.h>

Servo myservo; 

void setup()
{
  myservo.attach(2);  // attaches the servo on GIO2 to the servo object
} 

void loop() {
  // put your main code here, to run repeatedly:

}

- Thu Jun 18, 2015 10:52 pm #20876 Has anyone been able to get Servo to work under Arduino IDE for ESP yet?
I'm getting the same error about timercallback not being declared.
An explanation on how the IDE decide which include path(s) to use would also be helpful.
