* Don't Return I2C_ERROR_CONTINUE on ReSTART ReSTART operations on the ESP32 have to be handled differently than on AVR chips, so ReSTART operations(`Wire.endTransmission(false), Wire.requestFrom(id,size,false);` are queued until a STOP is send (`Wire.endTransmission(TRUE), Wire.endTransmission(), Wire.requestFrom(id,size), Wire.requestFrom(id,size,TRUE)). To indicate the queuing I had used `I2C_ERROR_CONTINUE`, this caused compatibility issues with the existing Arduino I2C Code base. So, back to Lying to the public(for their own good of course) about success! This update just returns `I2C_ERROR_OK` on ReSTART commands. * add comments add comments * Change Return error for ReSTART operation to I2C_ERROR_OK This change restores compatibility with pre-existing Arduino Libraries. The ReSTART queuing operations are hidden behind the scenes. Wire.endTransmission(id,len,FALSE); will know return I2C_ERROR_OK instead of I2C_ERROR_CONTINUE, Wire.lastError() will return the true condition of I2C_ERROR_CONTINUE. |

Development Status
Most of the framework is implemented. Most noticable is the missing analogWrite. While analogWrite is on it's way, there are a few other options that you can use:
- 16 channels LEDC which is PWM
- 8 channels SigmaDelta which uses SigmaDelta modulation
- 2 channels DAC which gives real analog output
Installation Instructions
- Using Arduino IDE Boards Manager (preferred)
- Using Arduino IDE with the development repository
- Using PlatformIO
- Building with make
- Using as ESP-IDF component
- Using OTAWebUpdater
Decoding exceptions
You can use EspExceptionDecoder to get meaningful call trace.
Issue/Bug report template
Before reporting an issue, make sure you've searched for similar one that was already created. Also make sure to go through all the issues labelled as for reference.
Finally, if you're sure no one else had the issue, follow the ISSUE_TEMPLATE while reporting any issue.

Hint
Sometimes to program ESP32 via serial you must keep GPIO0 LOW during the programming process
