2020-11-01Improve reading ADC resultVitaly Shmagun
7.3.0-atmel3.6.1-arduino7 gcc fails to optimize separate reading from ADCL and ADCH. It produces additionally three eor commands or in some cases two mov commands in the assembly code (see discussion #344). These commands swap register contents before store them to data area. So they are completely unnecessary. Reading ADC result with ADC macro fixes it and gcc generates the right code..

2019-06-08Do not claim AT-protocol in CDC interface descriptorMatthijs Kooijman
The CDC code presents itself as a virtual serial port. However, it also sets the "bFunctionProtocol" value to 1, which means it supports AT-commands, which is not actually the case. This might cause problems with some software, such as ModemManager. Originally, ModemManager would be very liberal with probing serial devices, using a blacklist to prevent probing non-modems such as Arduinos. Since version 1.7.990, it has supported a "strict" mode where it tries to be more restrained in what devices it probes. For CDC ACM devices, this means it will only probe devices that claim to support AT-commands. However, it also stopped applying the blacklist (intending to eventually remove the blacklist), meaning it would again probe Arduinos. This new strict policy is not the upstream default, but is enabled in Debian (since Buster) and Ubuntu (since bionic 18.04.2). The proper way to fix this, is to not claim AT comand support in the USB device descriptor, which is what this commit does. The Arduino will still show up as a virtual serial port, just not be probed by ModemManager in strict mode. For the commit that introduced the strict mode in ModemManager, see https://cgit.freedesktop.org/ModemManager/ModemManager/commit/src?id=ee570d44dc117dc69f23e83313dd877f76c5e3e0

2019-01-21Add parameters names to common prototypesPaul R. Nash
Putting the parameter names in these commonly used prototypes makes syntax help like VS Code's Intellisense work 99% more useful. Without them, it doesn't give you the names of the parameters and you have to remember the semantics yourself. :(

2018-12-11Add USBDevice.isSuspended()Gergely Nagy
Based on code originally by Rob van der Veer <rob.c.veer@gmail.com>, this adds USBDevice.isSuspended(), so user sketches can run custom code in their `loop` methods after checking if the device is suspended or not. Signed-off-by: Gergely Nagy <algernon@keyboard.io>

2017-11-13Fix flush hanging issueJohn Holman
Make write to UDR and clearing of TXC bit in flush() atomic to avoid race condition. Fixes #3745 (second different issue introduced later but discussed in the same issue)
2017-11-13Improve how TXCn bit is cleared in USCRnA registerJohn Holman
Preserve values of configuration bits MPCMn and U2Xn. Avoid setting other read-only bits for datasheet conformance. See #3745
2017-11-13Prevent buffer retransmission when transmit buffer is emptyJohn Holman
Moving the head buffer pointer and setting interrupt flag is now atomic in write(). Previously an intervening ISR could empty the buffer before the second ISR is triggered causing retransmission. Fixes: #3745 (original issue only)
2017-11-13Create macro to guard critical sections for large transmit buffersJohn Holman
New macro TX_BUFFER_ATOMIC makes the following code block atomic only if the transmit buffer is larger than 256 bytes. SREG is restored on completion. The macro is then used to simplify code for availableForWrite()
2017-11-13Always read key to check for new LUFA bootloaderScott Allen
Instead of checking for the NEW_LUFA_SIGNATURE once in program memory and then setting a flag which is used for further checks, a function is used that always checks program memory directly. If a flag is used, there's a slight chance that its location in RAM could fall on MAGIC_KEY_POS. In this case, an aborted USB auto-reset sequence may fail.
2017-11-13Don't use line coding to trigger USB auto-resetScott Allen
An auto-reset invoked using USB CDC is triggered by the port closing (when set to 1200 baud). Closing of the port is indicated by DTR going inactive. There is no need to have auto-reset invoked by a CDC_SET_LINE_CODING command. Only the CDC_SET_CONTROL_LINE_STATE command, which indicates a change in the state of DTR, should be used.
2017-11-13Save/restore the watchdog during USB auto-resetScott Allen
The state of the watchdog timer is saved during a USB auto-reset and then restored if the reset is aborted, in case the sketch is using the watchdog.
2017-11-13Fix save/restore of magic key location during resetScott Allen
In the USB CDC code to invoke an auto-reset, the magic key location could be restored before it had actually been saved. The sketch would then have a corrupted value at this location. This fix prevents the value from being restored if it hasn't previously been saved.

2017-05-23Move the flush method from Stream to PrintMatthijs Kooijman
This method originally flushed pending input bytes, which makes sense in Stream. At some point it was changed to flush output bytes instead, but it was never moved to Print to reflect this. Since Stream inherits from Print, this should not really affect any users of the Stream or Print classes. However to prevent problems with existing implementations of the Print class that do not provide a flush() implementation, a default implementation is provided. We should probably remove this at some point in the future, though.

2017-01-07Change double quotes to single quotesPatrick Roncagliolo
- "." is a string literal, and so is treated as the char '.' plus the null char '\0'. - Single quotes reduces the necessary memory for this literal to only one char instead. A string literal as the one actually present may require the use of the method "write(const char *str)", so there could be also a performance overhead. - Another reason to change quotes style is for consistency with line 235.
