The Official Arduino AVR core
If zero number of bytes are requested from any existing device on the I2C bus with `Wire.requestFrom( i2c_address, 0);` then the acknowledge from that device makes the Wire library read...
### Describe the request Expand the instructions for building the repository's arduino-usbserial firmware to provide all information needed to ensure a successful build by anyone. ### Describe the current behavior...
### Describe the problem #### Background When an "Export Compiled Binary" operation is performed, the Arduino development tools generate two variants of the binary: - The sketch application alone (e.g.,...

http://forum.arduino.cc/index.php?topic=303922.0 By using digitalWrite for analogWrite values of zero and 255 the AVR core creates a situation that can cause a glitch. The solution is simple. Do not treat zero...
When I had the need for a bigger 'Wire' buffer, I came up with this implementation. - Existing sketches work like before, but just with one additional macro in the...
Added a new function named melody() so that user can play melody tone by passing pin number,an array of notes and an array of duration in ms
Update total of available tone pins and properly restore PWM function when disabling the timers.
