* 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
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.
Original work by @ourairquality
* Sysparam threadsafe and SPI access
* Sysparam test cases
* Fix for negative int8
* Sysparam getting bool without memory allocation. Bool tests.
* SPI flash refactoring.
* Extract common spiflash.c into core.
* Use spiflash.c in sysparam.
* Use memcpy in spiflash.c insted of hand-written version.
* Tests for spiflash.c
* 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.
WDT is countdown timer. Current value is accessible via VAL register. At
this time it's unclear if it's RO or RW (common sense says it shoul be RO).
Source: looking at the WDT registers on a running chip.
* Sysparam implementation
sysparam improvements
Mostly done, a few minor cleanups left.
Add sysparam_editor example
Sysparam code cleanup
Add documentation to sysparam.h
Fix up sysparam.h docs
Added a couple more debug statements
Fix potential memory leak if realloc() fails
Major sysparam overhaul
Add sysparam_get_info function
Add sysparam initialization to app_main.c
* Fixed warnings, added license
In case of heap corruption or some other major problem, dumping details
in the exception handler can cause a crash loop - so fail out if we seem
to be going in circles.
Also reduces the IRAM footprint of the fatal exception handler, as only
the prelude (which disables interrupts & enables the flash mapping) is
in IRAM now.
Closes#54, relevant to #133.
