Zach Eveland dd55096901 added a short delay and comment to boolean operator in CDC
Delay fixes problem where the port has been configured but not quite opened.  Federico found that 10 ms was the minimum time needed to avoid problems.

Zach Eveland a984b581a8 added Boolean operators to HardwareSerial and CDC to test whether the port is ready to send data.
Mostly useful for Leonardo - simple way to test whether the port is actually opened by an application and ready to receive data.  For Serial objects attached to real UARTs always returns true.

Zach Eveland 8c618773b5 reduced delay before starting the Leonardo bootloader
Since we use a magic RAM flag to signal to the bootloader there's a risk of the sketch overwriting the magic RAM location before the bootloader starts.  By reducing the watchdog timeout we reduce the chance of this happening.

Zach Eveland c8ca7f9636 changed auto-reset logic for Leonardo. only do WDT manipulation if the port is opened at 1200 bps. (Dave Mellis) 2012-03-01 08:51:16 -05:00
Cristian Maglie 73066a4ca2 Autoreset 1200 bps fix. 2012-02-27 17:41:38 +01:00
Zach Eveland 0138ee9b01 shortened the watchdog period for resetting Leonardo from 2 s to 250 ms. Reset into bootloader is much snappier. 2012-02-22 22:33:44 -05:00
Zach Eveland 7948125208 Leonardo now checks whether bootloader should be run after a WDT event.
Before the sketch initiates an auto-reset for upload it pokes a magic word into a specific RAM address.  On starting the bootloader checks this address.  If it finds the magic word it knows the bootloader code should run. If not it jumps straight back to sketch.

Test in a sketch by adding to setup():
wdt_enable(WDTO_2S);

Sketch should upload, start, run for two seconds, WDT, and sketch should restart (not bootloader).

Had to cut out unused descriptor code to make the bootloader still fit in 4k.

Zach Eveland 924e5a4846 Leonardo auto-reset-and-upload changes for Windows (explanation below)
On Windows COM port changes when board switched between bootloader and sketch.  No way to prevent this so now Windows users have to select the upload port separate from the comm port.  Also, handling of reset into bootloader was broken on Windows.  Would occasionally leave the original COM port completely unusable.  Changed the way this reset is initiated.
Finally, had to add upload.disable.flushing=true flag to boards.txt so IDE wouldn't try to flush the original COM port after it disappeared.

Zach Eveland d7b0507e8a fixed starting Leonardo bootloader from sketch
AvrdudeUploader class opens and closes Leonardo port at the magic baudrate before starting avrdude; reduced reset timeout from 250 ms to 15 ms

Zach Eveland 45d3b10295 Caterina now cleanly hands off operation to the sketch
had to remove TIMER1 operation from bootloader - was interfering with normal sketch operation

Zach Eveland 58fc0d17cc added asynchronous buffering of received CDC characters
This fixes the issue Federico reported where bytes written by host but not read by sketch would cause serial connection to lock up.  Ring buffer implementation is based on HardwareSerial.cpp.

Adds public accept() method to CDC.

Zach Eveland 4b7771a815 restored original non-interrupt-driven DiskLoader
Interrupt-driven version was a dead-end - too many bugs with that approach.

Zach Eveland 415a5e119d changes in core and boards.txt to support new bootloader
old bootloader could fit in only 2 kB of flash.  new version has to have a 4 kB block - jump-to address and boards.txt must reflect this.

Zach Eveland e52cf0e420 fixed bug where sketches over 28k caused subsequent auto-reset-and-upload attempts to fail. fixed bug in reboot routine, changed fuses to select 1024-word bootloader size, disabled hardware boot enable. 2011-09-08 19:31:18 -04:00
Zach Eveland d81084e8e9 changed auto-reset trigger condition to fix auto-reset-and-upload for Windows. now reboots when a port, opened at 1200 bps, is closed. 2011-09-06 20:58:00 -04:00
Zach Eveland 95fd39090e changed baudrate for auto-reset-and-upload back to 1200 bps. specified arduino protocol for Leonardo avrdude upload. 2011-09-05 13:08:05 -04:00

Zach Eveland 39e0796aad auto-upload-and-reset works now at 300 bps. patched avrdude for Mac to support 300 bps connection, changed core and boards.txt to match 2011-08-27 20:32:34 -04:00
Zach Eveland f0ac64d2db bugfix - Serial.write() would try to send even if no CDC connection was open. 2011-08-24 21:04:30 -04:00
Zach Eveland 160bf890e0 changed auto-reset method for upload: now triggered by opening port at 1200 bps 2011-08-24 17:12:28 -04:00
Zach Eveland 84c0d2cff8 Temporary fix for auto-reset from IDE. Will reset chip when DTR is asserted, no matter what CDC baud rate is selected. 2011-08-16 13:43:55 -04:00
