ard-reset-leonardo which was used for reseting Leonardo was written in Python. Now the logic is added inside the ard-reset-arduino perl script itself. Fix #62 Squashed commit of the following: commita63366980fAuthor: Simon John <git@the-jedi.co.uk> Date: Fri Jun 14 11:36:00 2013 +0200 who put a space in the shebangs?! commitc798eb26eaAuthor: Simon John <git@the-jedi.co.uk> Date: Fri Jun 14 11:10:12 2013 +0200 replaced ard-reset-leonardo with an update to ard-reset-arduino which is now called from Arduino.mk with the --leonardo flag removed some trailing whitespace upped version string in Arduino.mk

ard-reset-arduino - Reset an Arduino

|
|
|
=head1 USAGE
|
|
|
|
$ ard-reset-arduino /dev/cu.usb*
|
|
|
|
$ ard-reset-arduino --verbose --period=0.1 /dev/cu.usb*
|

|
|
$ ard-reset-arduino --verbose --leonardo /dev/ttyUSB0
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
To reset (most) Arduinos, it's enough to just pulse the DTR line.
|
|
|
|
You can do that from the shell with stty, but there's an interesting
|
|
diversity of command flags. This little program gives a uniform interface
|
|
at the cost of requiring C<Device::SerialPort>.
|
|
|
|
=head1 OPTIONS
