* Add testing branch to workflow * Add workflow * Checkpoint * Align SPI data rates in c++ code with Python code. * Checkpoint * CI fixes * Update codeowners * Workflow cleanup * Rename to spi_rgb_led * Rename header file * Clang tidy * Disable spi after transfer. * Move enable() to where it belongs * Call spi_setup before enable * Clang tidy * Add test * Rename to spi_led_strip * Include 'defines.h' * Fix CODEOWNERS * Migrate data rate to new style setting. * Remove defines.h * Fix class name * Fix name in .py * And more more name tidy up. --------- Co-authored-by: Keith Burzinski <kbx81x@gmail.com>
