gettimeofday used to return timestamps which had tv_sec 1000 times smaller than the correct value.
s_bootTime is in seconds, so no need to divide it by 1000.
* Fix analogWrite
Move to NMI interrupt
Rework the whole ISR to take less and more constant cycles
Current defaults run 10bits/1KHz@160MHz and 9bit/1KHz@80MHz (soft
mapped)
* astyle and remove STORE_ATTR
This will allow using the String library in a ranged for loop:
```C++
String s("Hi, this is a test");
for (const char& ch : s) {
Serial.print(ch);
}
```
and even modify
```C++
String s("Hi, this is another test");
for (char& ch : s) {
ch++;
}
Serial.println(s);
```
* Use newlib libc library
This change adds libcmin.a, which is created from newlib libc by selectively removing some of the object files (mostly related to heap management).
The list of files is available in tools/sdk/lib/make_libcmin.sh. Files which are not needed are commented out.
This change adds support for various functions which were missing, like sscanf, strftime, etc.
* Fix some of the time functions
* Redirect stdout to serial
* Implement __putc_r
* Switch to custom newlib build

* Added Serial.baudRate() to get current baud rate
* Added more description
- Added note about Software Serial Implementation
- Indicate this will works on ESP8266 boards only
I2C slave might stil have something to send when ESP826 starts I2C, thus
keeping the bus stuck.
Happens e.g. when power failure/reset during transmission.
Thanks to work of drmpf there is a solution.
Implemented as separate method so as not to interfere with existing.
Usage:
Wire.begin();
if (Wire.status() != I2C_OK) Serial.writeln("Something wrong with I2C
bus that cannot be recovered. Perform power cycle or search for other
masters on bus.";
The change in 297bb17 enabled RF after deep sleep, even if deep sleep was done with RF_DISABLED option (thanks @vlast3k for pointing this out).
Now we check the value returned by __get_rf_mode, and only call system_phy_set_rfoption if RF_MODE override was provided by user.
