support old v1.0 library format which can put files in the 'utility' subdirectory

• 1.6.0 (2024-07-25)
  • Add strncat_P() to pgmspace.h.
  • Add ESP.restart() and ESP.getChipId(). See
    PR#84.
  • Support files located in the utility subdirectory for libraries using
    the old v1.0 format. Fixes
    Issue#89.

1.5.0 - support C files; add ARDUINO=100 macro; add 'make run' target

• 1.5.0 (2022-12-08)
  • Support compiling plain *.c files in libraries and in the application.
    • The C files are assumed to be written in C11.
  • Define the -D ARDUINO=100 macro.
    • Some 3rd party libraries test for ARDUINO >= 100 to check if it's
      being compiled under Arduino.
    • Many will compile under EpoxyDuino with this macro set.
  • Add make run target which runs the binary generated by make all.
    • Useful in the vim editor where :make run will invoke the quickfix
      feature so that the editor will jump directly to the file and line
      where the AUnit assertion failure occurred.
    • Update the example for loops to invoke make -C {dir} run instead
      of running the binary directly. The vim editor can parse the output
      caused by the -C flag, and automatically generate the correct path
      to the files in the subdirectories.

1.4.0 - add Udp.h; implement stubs of configTime()

• 1.4.0 (2022-11-06)
  • Add memcmp_P() by @dawidchyrzynski in
    PR#71.
  • Add Udp.h interface supporting both the AVR and ESP8266 variants.
  • Provide actual stub implementations of configTime() for ESP8266.

v1.3.1 - allow mocking of digitalWrite(); add stubs for tone() and noTone()

• 1.3.1 (2022-08-13)
  • Add tone() and noTone() stubs. By @kwisii in
    PR#69.
  • Add uint8_t digitalWriteValue(pin) which returns the value of the
    most recent digitalWrite(pin, val). By @kwisii in
    PR#68.

v1.3.0 - add EXTRA_CPPFLAGS; add digitalReadValue(); add EpoxyDuino.h to suppress warnings; add EpoxyMockSTM32RTC

• 1.3.0 (2022-03-28)
  • Add support for EXTRA_CPPFLAGS, similar to EXTRA_CXXFLAGS.
  • Add digitalReadValue(pin, val) to control the return value of
    digitalRead(pin).
    • May be useful for testing purposes.
    • The pin parameter must satisfy 0 <= pin < 32, otherwise
      digitalReadValue() is a no-op.
    • See PR#61.
  • Add an empty EpoxyDuino.h at the top level to stop warning messages from
    the Arduino IDE.
    • Fixes Issue#62.
  • Add libraries/EpoxyMockSTM32RTC
    • A mock of the STM32RTC
      library.

v1.2.3 - add enableTerminalEcho(); upgrade to using pre-installed LittleFS library on ESP32>=2.0.0; add notes about using Valgrind

• 1.2.3 (2022-02-24)
  • Rename unixhostduino_main() to epoxyduino_main(), and make it
    static. No need to expose it publicly.
  • Add enableTerminalEcho() function to enable terminal echoing.
    See Enable Terminal Echo.
  • Update examples and EpoxyFS/README.md to be
    compatible with new LittleFS library in ESP32 >=2.0.0.
  • Add EpoxyFS/SeekBenchmark to
    measure the performance loss of calling seek() before a read().
    • Sometimes the client-code is simpler when reading multiple records
      if it can call seek() with an explicit offset before each read().
    • The alternative would be calling read() multiple times sequentially
      and using its internal cursor to advance automatically.
    • This benchmark shows that seek() causes significant performance
      loss, even if the seek() offset is identical to the internal cursor,
      so might be expected to be optimized away.
  • Add notes about Debugging tools and options
    under a Unix environment, such as Valgrind.

v1.2.2 - inherit overloaded Print::write() methods into StdioSerial class

• 1.2.2 (2022-02-02)
  • Add a using Print::write statement in StdioSerial.h to
    pull in all other overloaded write() methods from the parent Print
    class.

v1.2.1 - add strncasecmp_P(); update README.md doc

• 1.2.1 (2022-01-10)
  • Add strncasecmp_P() to pgmspace.h. See
    PR#52.
  • Add Bugs and Limitations section in
    README.md
  • Add comment in
    github/workflows/aunit_tests.yml
    that a pull_request event may be useful. Upgrade GitHub docker image to
    Ubuntu 20.04.

v1.2.0 - simplify StdioSerial; revert Print::println() line terminator, and make it configurable

• 1.2.0 (2021-12-29)
  • Simplify StdioSerial class, see
    Issue#43.
    • Replace input ring buffer with a buffer of one character.
    • Wire StdioSerial::write(uint8_t) directly to Posix write(),
      by-passing the <stdio.h> buffer. flush() is no longer necessary.
    • Thanks to @felias-fogg.
  • Revert Breaking Change Made in v1.1.0 Revert 432e304, so that
    Print::writeln() writes \r\n again by default.
    • Fixes Issue#45.
    • Add Print::setLineModeNormal() and Print::setLineModeUnix()
      methods to control the line termination behavior.
    • See README.md#UnixLineMode for usage info.

v1.1.0 - add more Arduino.h functions and macros; add mock FastLED library

• 1.1.0 (2021-12-09)
  • Add optional DEPS variable containing header files that the *.ino
    depends on.
  • Potential Breaking Change Print::println() to print just a \n
    instead of \r\n.
    • This is more compatible on Unix where the line terminator is a single
      \n
    • This allows the text output of Arduino programs to be redirected to
      a file or piped to another Unix program with the correct line
      termination character.
    • This change may break some programs (usually unit tests) which print
      to a
      PrintStr
      object (from my AceCommon
      library), and then expect \r\n instead of \n.
