A collection of minor changes to be more consistent with other examples: - capitalize comments - add line offset to value outputs - drop comma from edge event outputs - improve behaviour if run on a platform that does not match the example configuration - use with to cleanup request in toggle_line_value.py Signed-off-by: Kent Gibson <warthog618@gmail.com> Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>
