* 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
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()`
