Teensy Compatibility #142

Open dave-newson opened 9 years ago

dave-newson commented 9 years ago

Following on from issue https://github.com/queezythegreat/arduino-cmake/issues/67, this PR adds support for Teensy boards and the Teensy SDK for arduino-cmake. The crux of this PR is adding additional compile options and detecting/using teensy_loader_cli (halfkay) over avrdude for uploading.

Teensy-specific board modes that are available (usually speed, usb and keys) can be listed using the following command: print_teensy_modes(board_id) where board_id is the specific Teensy board identifier. The options available for each mode can be viewed using: print_teensy_modes(board_id MODE mode_id) where mode_id is the mode (eg. speed) you want to view options for.

Three specific options must be set for the Teensy board to compile correctly: set(TEENSY_CPU_F_MODE 16) set(TEENSY_USB_MODE serial) set(TEENSY_KEYBOARD_MODE en-us)

If the Teensy board is detected (usually specified in the Teensy boards.txt config via the <board_id>.upload.protocol value as halfkay), the teensy_loader_cli will be used. All other options (or null) default to avrdude, as before.

Some additional support for teensy-specific build flags has been added, allowing <board_id>.build.optionX definitions to be imported from the the boards.txt file as compile flags.

Failing to define a F_CPU will now also raise a fatal error. This is a common hiccup when trying to set up arduino-cmake with a Teensy.

Requires (and integrates) PRs https://github.com/queezythegreat/arduino-cmake/pull/141 and https://github.com/queezythegreat/arduino-cmake/pull/140.

Please note I only have a Teensy, so I haven't been able to thoroughly test this against standard arduino boards.

What about this PR? would really like see it merged.

dave-newson commented 9 years ago

@filosganga iirc I ran into some problems with this and compiling out to Teensy 3. Does work with Teensy 2++, mind you, so it's at least a step in the right direction.

thanks

For what it's worth to anyone else who happens across this PR, I've abandoned trying to make this work in favor of using PlatformIO for the same cross-OS compiling. There were too many variables with the Teensy3 for me to understand, which they seem to have resolved.

Will leave this PR open, but I now feel it's incomplete. I'll leave it up to the project maintainer to decide its fate.
