* The default timings were chosen vastly outside specification. On COTS servos, this causes much confusion for the user, because a wide range of angle starting from 0 degress, and a just a large range of angle leading up to 180 degrees, is dead - in fact, the servo doesn't move at all, from any position.
Not investigated further for obvious reasons, as this may have also destroyed servos that ran hot trying to abide by the PWM signal but could not mechanically!
* Change timing limits to safe values. With previous default timings and safety limits, popular servos
could force against internal physical endstops, which could overload and destroy them.
* Review action: revert changes to hard boundary for min/max duty cycle timings. Internal review, fix/drop legacy comments.
* A Servo on each available ESP8266 GPIO (D0-D8), no observed interference.
* Remove possible jerk due to force-cancelling duty cycle.
* Overload attach: can specify initial angle for servo, too.
* Stricter checks for configured, and default, bounded timings.
* Missed the min/max in a comment.
* Default microsecond lower bound of 1000 causes confusing behavior - 200 is minimum enforced elsewhere, so use it here too as nearest multiple of 100 from 180.
* Comment rationale for changed defaults of min/max pulse widths.
Comment rationale for changed defaults of min/max pulse widths.
The boundary parsing in the webserver could end up missing boundaries if the
uploaded file had `--` at the start of the line because it read in the entire boundary
length worth of bytes. Fix by only reading up to either the boundary length or
a newline, avoiding the issue.
Fixes#7542
The SDFS implementation didn't include plumbing to support user-supplied
timestamp generators (for file create/write times) because the SDFat
library doesn't support a callback parameter.
Work around it by using a single, global (inside sdfs namespace) that
the static timestamp callback member can see and use.
Add a test of the feature in CI.
Fixes#7682
Fixes#7671
Allows for code to do things like read certs from LittleFS or even HTTP
connections with code like:
File cert = LittleFS.open("/client-crt.pem", "r");
clientCert = new X509List(cert, cert.size());
cert.close();
* Add Print::availableForWrite method
Adds an availableForWrite() method to the Print class, matching current
ArduinoCore-API commit 398e70f188e2b861c10d9ffe5e2bfcb6a4a4f489 .
Hook availableForWrite into the SDFS filesystem (other FSes don't have
this capability built-in).
Fixes#7650
* WiFiClient::availableForWrite proto matching Print
* Fix Netdump signedness warning
* Clean up Serial availableForWrite
This is evidently a breaking change due to the type difference.
Arduino's `availableForWrite` returns an `int`, while the
(multiply-implemented, non-virtual) core `availableForWrite` returned
`size_t`.
When building with the Netdump library, the IDE generates the following warning:
> WARNING: library Netdump claims to run on (esp8266 lwip) architecture(s) and may be incompatible with your current board which runs on (esp8266) architecture(s).
Fix the library.properties to call the architecture just "esp8266"
* Add Wrong Password wifi status case
* Add wrong password case for status return
* Add wrong password case for debug
* Add Wrong password case to interactive example
* Add case for wrong password to station doc
* Add case for wrong password to resumeFromShutdown
* Add wrong password case to wifi readme
* Update ESP8266WiFiGeneric.cpp
Fixed critical issues WiFiMulti library:
- WiFi scan timeout implemented to prevent endless connect loop
- Fallback implemented on WiFi connect failure to prevent endless loop
- Fast WiFi connection at startup
- Improved debug prints
- Doxygen added
- Code maturing
- Example update
Make functions not related to ESP8266WiFiMulti class static
Revert static functions startScan and printWiFiScan()
Use PolledTimeout.h to protect while loops
Move static functions beginning of the file
Add connect timeout to example
* Update certs-from-mozilla.py
Check if ar exists, if not tell the user what to get to prevent issue #7300 also dynamically get certs instead of hardcoded row item https://github.com/esp8266/Arduino/pull/7573#issuecomment-686192353
changed comment for missing ar exception
updated path and check for openssl
Simple example update to pass the method as a parameter to getDigestAuth(), so it is more easily used for POST.
Add setting the ransom seed to RANDOM_REG32 in setup() for better getCNonce() values.
The logic can be simplified by using integer logic without a functional
change. Reduces code size by 40% (78 bytes -> 46 bytes) and silences
a Warith-conversion warning.
Converting floats to doubles is very expensive on esp8266, so prefer
calculations or comparisons as float. This saves 10% (20 bytes) of the
String::parseFloat() code size and probably quite a bit of runtime
overhead.
