* overload Preferences.getBytes similar to nvs so you can get size of the array.
* Cleaner implentation, with a separate function to get length. Added an example
Currently WiFiClient::write is unable to send messages over 25Kb, because of the hard-coded retry limit of 10, that is getting decremented on every successful send. Since we cannot send more than 2*MTU bytes in one go, and have only 10 retries, write() is limited to approximately 25Kb. Technically it is not a bug, as it correctly returns the number of sent bytes and the caller can set up futher retries. But not all libs are aware of this behavior, for example, WebServer is not.
I suggest improving current behavior by resetting retry counter every time we had a successful write, so the limit of 10 retries will apply to Failed writes only, and will not apply to Successful writes. This will allow to write() blobs of arbitrary sizes.
* Added 2 ffat partition schemes for 4MB modules + improved descriptions.
Existing format options were unclear on how much spiffs you were
getting. Also add missing 1MB App/3MB Spiffs split.
This addresses https://github.com/espressif/arduino-esp32/issues/1799
This makes it very clear what each option gives you, and also adds 2 options
to get ffat on 4MB chips..
* Added link to ffat howto.
* Update boards.txt
Add menu items for ffat on mhetesp32minikit board.
* Add partition table.
* Added ffat partition for 4MB ESP32 Dev Module.
* Added comment about partitioning schemes.
Adding the -g3 flag that was omitted in the PIO build script but is present in Arduino IDE build scripts. This flag restores the ability to get line numbers from stack traces for elf files generated in PlatformIO IDE.
* Add default pin mapping for Serial1 and Serial2
* Default pin remap on wESP32
Improved default pin mapping for I2C0 and UART1 to avoid issues
with programming.
SDA0 was on IO2 but IO2 needs to be pulled low on reset to enable
serial programming, which conflicts with I2C pull-ups.
RX1 was on IO12, idle UART level is high which conflicts with
IO12 needing to be low on reset to select correct 3.3V flash
voltage.
New mappings:
SDA0 on IO15
RX1 on IO13
TX1 on IO12
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
