* Add APB change callbacks and move cpu code to own file * Properly set esp_timer and FreeRTOS tick dividers * Improve updated devisors * No need to update REF_TICK yet * Add initial handling for UART baud change * fix uartWriteBuf and uartDetectBaudrate * trigger callbacks even when APB did not change * toggle UART ISR on CPU change * add XTAL freq getter and add cpu freq validation * Support CPU frequency changes in I2C (#2287) **esp32-hal-i2c.c** * add callback for cpu frequency changes * adjust fifo thresholds based on cpu frequency and i2c bus frequency * reduce i2c bus frequency if differential is too small **Wire.h** * version to 1.1.0 * Implement clock change for the other peripherals * remove bad CPU clock values from the menu * Add note to CPU freqs that support WiFi and BT

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
