In Board.txt file added board revision submenu to distinguish the different revisions of the same board. By selecting different revision in the Arduino menu different value of the predefined macro will be applied which is used inside the pins_arduino.h file to make different defines and values for the specific revision.
In addition to this esp32-poe pin definitions is added ethernet power enable pin and also defined macro: BOARD_HAS_1BIT_SDMMC
* Board T-Beam: Update pins_arduino.h
DAC2 is not wired, only DAC1 is -> corrected
LORA pins 27 + 19 are only wired on pcb, but not connected to header -> deleted
* Update pins_arduino.h
Button and LED added
* add missing EEPROM lib to CMakeLists.txt, moved the EEPROM files to proper directory
* add missing EEPROM lib to CMakeLists.txt, moved the EEPROM files to proper directory
* Webserver fix logging (#1)
* Change logging to use esp32-hal-log.h
fixes#2355
* adjust log parameter output positions, reduce lines
The DEBUG_ESP method used less lines than I originally set `log_v` to use when displaying the details of the received params ("@" and "=" indexes, and File info on a single line)
* I2C debugging and Log Dump Explaination
Create a help file for I2C debugging and interpretation of log dumps
* Update i2c_debugging.md
version
* add formatting, file locations
The i2c peripheral will hang if a READ request is issued with a zero data length. The peripheral
drops into a continuous timeout interrupt response. The STOP command can not be set out to the I2C
bus. The SLAVE device correctly ACK'd the address byte, with READ bit set, it has control of the SDA
pin. The ESP32 send out the next SCL HIGH pulse but, since the SLAVE is in READ Mode, and the First
bit it is sending happened to be a ZERO, the ESP32 cannot send the STOP. When it releases SDA during
the SCL HIGH, the pin does not change state. The pin stays low because the SLAVE is outputing a LOW!
The ESP32 drops into a perminent WAIT state waiting for SDA to go HIGH (the STOP).
**esp32-hal-i2c.c**
* add databuff length checks to `i2cRead()` and `i2cWrite()`
* 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
The default SPI bus is VSPI (see libraries/SPI/src/SPI.cpp). This change corrects a misleading comment in a code example which was stating wrongly that HSPI would be the default one.
* Shows only free internal heap on logs
Since Mbedtls is running only on internal heap, show internal + PSRAM available memory on logs can confuse the users
* Clarify logs
