From 3563d4f24582bd3e580347ccf4d069453108e08f Mon Sep 17 00:00:00 2001 From: Calvin Li Date: Fri, 3 Apr 2015 22:37:51 -0700 Subject: [PATCH] Fix reset for leonardo I found that the previous reset code did not work for Leonardo or Micro, nor did any reset code anywhere on the internet. An examination of the Arduino IDE source code (and the JNI code behind its serial implementation) shows that it holds RTS high and DTR low when doing the 1200 baud open/close. And it turns out that's exactly what's needed! --- bin/ard-reset-arduino | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/bin/ard-reset-arduino b/bin/ard-reset-arduino index ed22a63..3e43486 100755 --- a/bin/ard-reset-arduino +++ b/bin/ard-reset-arduino @@ -17,10 +17,10 @@ if args.caterina: if args.verbose: print('Forcing reset using 1200bps open/close on port %s' % args.port[0]) ser = serial.Serial(args.port[0], 57600) ser.close() - ser.open() - ser.close() ser.setBaudrate(1200) ser.open() + ser.setRTS(True) # RTS line needs to be held high and DTR low + ser.setDTR(False) # (see Arduino IDE source code) ser.close() sleep(1)
