This code allows Wire.begin() to assign the default values of SDA, and SCL only if they have not been previously configured. Arduino libraries that use Wire() usually re-init the I2C interface in their initialization code with a call to Wire.begin(). If a user app sets custom pins assignment in setup(); These assignments will be overwritten with the default values whenever Wire.begin() is called.
M5Stack variant (pins_arduino.h) file is not automatically included,
because boards.txt m5stack-core-esp32.build.variant=esp32
This commit changes m5stack-core-esp32.build.variant from esp32 to m5stack_core_esp32
also rename M5Stack variant directory from m5stack-core-esp32 to m5stack_core_esp32
* Add BluetoothSerial library
A simple UART to Classical Bluetooth bridge for ESP32
* Create README.md
* Fix typos
* Replace deprecated header and small fixes
* Add coexistence with BLE
* Add missing semicolon
The cycle count that micros() is using to report timing is a PER Task value. When micros() or delayMicroseconds() is called from different Tasks, the lastCycleCount value may have no relationship to the current Task specific cycleCount. If the current cycleCount is less than the saved lastCycleCount a rollover condition is assumed. This erroneous conditions results in incorrect delays and reported microseconds. This fix creates thread local storage so that each Task will have accurate microsecond reporting and delays. The reported microseconds are not real time, they are microseconds of the current Task execution.
The ESP8266 version of the mDNS library expected service name and protocol without leading '_' (underscore). The ESP32 version expected service name and protocol with leading '_' (underscore).
This small change makes the ESP32 version compatible with the ESP8266 version and keeps backward compatible with existing code by accepting service name and protocol either with or without leading '_' (underscore).
esp_efuse_mac_get_default() only stores into the bottom 6 bytes of it's 8-byte argument, so must initialize this arg to zero to avoid trash on the stack.
* enchanced EEPROMClass
* Added eeprom examles and modified partition
* added eeprom class and extra examples
* No changes
* No changes
* added eeprom class and examples
* fixed typo
* length() returns user-defined sector size
* updated and annotated example
* Retrieve some code from what has been done on the ESP8266. Clarify a bit the signification of several bytes in the response.
* Add the type and class as members of the DNS class for an eventual future use.
* Clarify the sense of a magic number present in DNS server.
* A bit of aesthetics for the DNS server.
* Add a structure for the DNS question, use it DNS server to store the question data and to create the DNS answer from scratch.
* Added a lastError method to WiFiClientSecure so that a connection error from mbedTLS can be retrieved if connection fails (and then presented to a user).
* Changed to dos CRLF
* Made buffer size a const\nMore cleanup to match source
* Small grammar fixes and clarifications
Just fixed some small grammar issues in the comments and clarified a few things that might seem confusing.
* More spelling fixes that I introduced...
* Update mDNS and LEDC
* update toolchain
* Update IDF to 1c3dd23
* Advertise the board variant for Arduino OTA
* Add generic variant definition for mDNS
* Allow configuration of Ethernet PHY clock source

The internal APLL can be used to generate the 50MHz clock for the internal EMAC and the external Ethernet PHY.
The clock can either be input on GPIO0 (as before) or output on GPIO0, GPIO16 or GPIO17 (only GPIO17 extensively tested).
New example available.
