When user selected HSPI with SPIClass name(HSPI) ESP was, by default,
still using VSPI ports (the ones defined in pins_arduino.h).
With this change when user selects HSPI then HSPI default ports will be
used.
If user won't specify HSPI then VSPI default ports will be used.
If user will specify SCLK, MOSI, MISO and SS with SPI.begin() then user
defined ports will be used no matter if VSPI or HSPI is selected.
With this change fe. SD library can use default HSPI ports. It was
possible to
pass HSPI SPI instance to SD lib, however even then it was using VSPI
ports which were (probably) GPIO matrixed to HSPI.
* ArduinoOTA would stop receiving any packets if the port received a zero-length UDP packet, commonly sent by network scanners like nmap. Fixed to flush() after every call to parsePacket(), even if read length is 0.
Additionally, added length checking to fix a potential buffer overflow in parseInt().
Finally, added an end() method that stops the OTA listener and releases resources.
* Only end MDNS in end() if mdns mode is enabled.
* Create ledcWrite_demo_ESP32_RGB.ino
adding the public domain example ledcWrite_demo_ESP32.ino to this repo. Added RGB to the name for people searching, added some comments, and renames things to make a bit more sense.
* Update ledcWrite_demo_ESP32_RGB.ino
renamed to ledcWrite_RGB.ino and added a couple more comments based on https://github.com/espressif/arduino-esp32/issues/689
* Rename libraries/ESP32/examples/AnalogOut/ledcWrite_demo_ESP32_RGB/ledcWrite_demo_ESP32_RGB.ino to libraries/ESP32/examples/AnalogOut/ledcWrite_RGB/ledcWrite_RGB.ino
Renamed.
* Addition of a i2cReset method and timeout handling for the case where the i2c hardware FSM (state machine) gets stuck in a busy state.
* Use newly added i2cReset function within the wire library.
* Add example to update ESP32 via SD card
* Delete update.bin from sd upon finishing update
* remove precompiled binary from example
* Check whether update.bin is a file
* Change disconnect function
Current implementation does not disconnect the WiFi. Use of `esp_wifi_disconnect()` does.
* Update WiFiSTA.cpp
put back the clear ssid + password
remove the duplicate `esp_wifi_set_config(WIFI_IF_STA, &conf);`
send() can return a value > 0 but less than size indicating it was able to accept some of the data in buffer. The caller must try again after updating the buffer pointer and size remaining.
* Add files via upload
Calls to writePattern() don't send the desired number of bytes when the pattern size doesn't divide evenly into the hardware FIFO size (e.g. sending 18-bit RGB data, 11 patterns take 63 bytes, so 1/64th of the data is never sent).
* Add files via upload
Remove white space changes.
