- The newest Arduino IDE 1.6.12 has recently updated to avr-gcc v4.9.2.
Unfortunately, it produces a compiled size almost 0.7KB to 1KB larger
than prior versions! This can easily cause the base build to exceed the
Arduino Duemilanove/Nano flash limit of 30.5KB. The Arduino Uno seems
to be ok still with its 31.5KB flash limit.
- Makefile `-flto` compile flag added to cut down on the horrible flash
size when using the new avr-gcc. (Edit Makefile and remove comment on
COMPILE definition). This brings it in-line with what the IDE produces.
- Functionalized repetitive tasks in report.c to try to reduce overall
flash size. Successfully cut down about 160bytes.
- Removed printFloat_SettingValue() and printFloat_RPMValue()
functions. These aren’t required and can be replaced with a direct call
to printFloat() because they don’t require a unit conversion check.
- Reverted back the serial RX count function to how it was. The
variable type was unsigned and cause an integer underflow whenever the
calculation produced a negative number. The old way was the correct way.
- Lots of minor edits to the code CSVs and markdown documents.
- Expanded on explaining feedback messages and startup line execution
feedback.
- Created a new settings codes CSV to help GUIs import the values and
meanings.
- Incremented to v1.1a, rather than keep 1.0e. This is because there
are existing v1.0 installations. Don’t want to confuse people further.
- Certain version of the Arduino IDE did not like the `inline` in the
function header. Removed from spindle_control files to fix the problem.
- Tweaked the communication protocol slightly. Added message type
indicators for all `[]`bracketed feedback messages. It’s been
problematic for GUI dev to try to determine the context of a message
and how it should be handled. These indictors should help tremendously
to remove context all together.
- Also altered how `$N` startup lines are presented when executed. They
now start with an open chevron ‘>’ followed by the line and an ‘:ok’ to
indicate it executed. The ‘ok’ is on the same line intentionally so it
doesn’t mess up a streaming protocol counter.
- Managed to save a 100+KB from refactoring parts of report.c. (Thanks
Vasilis!) Freed up room to alter the protocol a little.
- Wrote a markdown document on interface messaging to make it clear how
it’s intended to work. See interface.md in /doc/markdown
- Started to pull in some Wiki pages from the old grbl site and
beginning to update them for v1.1.
- Created new commit log for v1.1.
