This patch gets the newlib standard stream descriptors playing well with the
lwip socket descriptors and the spiffs file descriptors. The LWIP_SOCKET_OFFSET
is now defined to be 3, rather than zero, to avoid clashing with the standard
stream descriptors, and the SPIFFS_FILEHDL_OFFSET is bumped up to start after
the lwip descriptors.
* bmp180: comment typo
* ds3231: minor code style fixes. Comment, on the week day start.
* Reverse engineered ets_timers.o Switch from FreeRTOS queue to task notification. Removed unknown/unused code. Rename sdk_ets_handler_isr to process_pending_timers. Add function for microseconds Simplify time to ticks conversion
* ets_timer: code for using the FreeRTOS timers, and remove from libs.
* libc: update to a recent newlib version.
* LwIP v2 support
* spi_write: use uint32_t for the page iteration counter. The page counter was using an uint8_t which seems unnecessary and might wrap.
* sysparam_get_bool: memcpy the binary values out.
* FreeRTOS 9.0.1
* Add an argument to ISRs. Disable interrupts while masking them.
* sysparam: reserve one more flash sector before placing the sysparams. This is to help work with recent SDKs that add a RF cal sector by default in the fifth last sector - just so the sysparam sectors do not jump around when using different SDK versions.
* upnp example: strip down the lwipopts.h file
* sysparam editor: accept newline to end a line of input.
* Add Wificfg. Uses the sysparam store to save the wifi configuration. Adds a basic http server for configuration.
* lwip: disable the tcpip_core_locking_input option. With this option enabled some lwip input processing occurs in the pp task which works well for some uses but some code uses a lot of stack (e.g. mdns) and will overflow the pp task stask, or might unnecessarily slow the critical pp task,
so disable this by default and if not already defined.
* sdk_cnx_add_rc: fix overflow of the table, when no match is found. Also adds source code for sdk_cnx_rc_search, adding a null pointer dereference. Check (that is not expected to be seen), and source code for sdk_cnx_remove_rc.
* http_get example: fix compilation with ipv6 disabled.
* lwip: update to master branch.
* wificfg: allow the AP channel to be 1.
* lwip: rework the tcp ooseq handling. It now accounts for the number of rx pool buffers used and the
available memory when deciding the number of ooseq buffers to retain. Enable the TCP Selective ACK support which appears to help a lot on lossy wifi when using the OOSEQ option.
* Update lwip, fixes losses of pcbs and associated problems.
* lwip: revise the tcp ooseq limit calulations. Was making a mess of the calculation sign. Also added a COPY_PP_RX_PBUFS define to include appropriate limits for this option.
* lwip: ooseq_max_bytes() - set a practical target memory size.
* lwip: revise ooseq handling. Modified for lwip backwards compatibility based on upstream feedback.
* lwip: update to the 2.0.3 release
* lwip: merge upstream master.
* libc: update to upstream master.
* lwip: fix building without TCP_QUEUE_OOSEQ
Looks like this was test wip code that should not have been included.
Want to be able to set the i2c per-project rather than having to patch
the driver.
mqtt_timer_left_ms: timer->end_time is in ticks, now is in ticks, so left
is in ticks. left * portTICK_PERIOD_MS is the time left.
With that change, the select in both mqtt_esp_read and mqtt_esp_write
seems to work as expected(with time, not ticks)
On MQTTClient.c function mqtt_subscribe, if more than MQTT_MAX_MESSAGE_HANDLERS are registered, the variable rc receives the value of grantedQoS.
If grantedQoS = 0, and all handlers are already occupied, it goes on and returns 0 to the caller.

The function sntp_set_servers() duplicates the strings supplied in the
server_url[] array into new strings but forgets to allocate the extra
byte needed for the \0 terminator for each string.
Fix the problem by using strdup(), which allocates the right amount of
memory and copies the string at once.
* Process rercursive folder for spiffs images
* Flat file name from the directory structure
* change method to find '/' as the suggestion of @sheinz
* remove unused variable
* Allow changing write function of stdout.
Required for stdout redirection.
Works on blocks, not chars - does _not_ use sdk_os_putc !
Should work even when linking with SPIFFS.
* bmp280 more options
add option to user for temp oversampling and possibility to skipp a specific measure
* Update bmp280.h
* quick fix oups
* less redundant terms
* Added a MQTT pub/sub example of using AWS IoT (via ECC based TLS1.2 connection).
* Fixed a buffer overflow issue when receiving large MQTT packet.
* Reset TLS connection on read/write errors.
The BME280 is close to compatible with the existing BMP280 and extends it with support for measuring humidity, so support has been bundled into the bmp280 driver.
The example now auto-detects the device and displays the humidity for the BME280.
The I2C bus initialization has been moved out of the bmp280 driver to support multiple devices.
The check-id and reset logic has been bundled into the driver initialization. It needs to be re-initialized after reset anyway and the chip-id is need to initialize it, just re-initialize to reset.
Support has been added for multiple devices. The calibration data storage needs to be managed by the caller rather than static data. The caller can choose the I2C address to allow two BMx280 devices to be used on the same I2C bus.
An interface has been added to return the measurement values in an integer fixed float format. The float format interface is still there.
All the values are read in one I2C transaction to ensure they are a consistent set.
Renamed bmp280_calib_t to bmp280_t, and removed read_register8.
An application using multiple I2C devices will need it's own
loop. This reworks the code to make the detection, calibration
constant loading, and measurment functions available too without
having to use the bmp810 task which is still retained.
Adds support for oversampling.
Fixes a bug in the calculation of the temperature.
Better error handling. Checks for I2C errors and errors in the loading
of the calibration constants and propagates these up.
Configure the pins as open-drain just in case the code forces them
high although it should be configuring them as inputs to let them float high.
Initialize the pins when the driver is initialized.
Enable the internal pull-ups to prevent them floating too high if not
connected and damaging the circuit.
