2015-01-26Simplify SoftwareSerial::writeMatthijs Kooijman
Before, there was nearly identical code for the inverted and regular cases. However, simply inverting the byte in the inverted case allows using the regular code twice, reducing the generated code size by 100 bytes (on an Arduino Uno and gcc 4.3, on gcc 4.8 the reduction is 50 bytes).
2015-01-26Use stopListening() in SoftwareSerial::end()Matthijs Kooijman
stopListening also disabled the interrupt, if needed, so calling that function makes more sense. Since stopListening only disables the interrupt when the current SoftwareSerial is the active object, and that can only be the case when _rx_delay_stopbit is non-zero, there is no need to separately check _rx_delay_stopbit anymore.
2015-01-26Fix race condition in SoftwareSerial::overflow()Matthijs Kooijman
If an interrupt causing overflow would occur between reading _buffer_overflow and clearing it, this overflow condition would be immediately cleared and never be returned by overflow(). By only clearing the overflow flag if an overflow actually occurred, this problem goes away (worst case overflow() returns false even though an overflow _just_ occurred, but then the next call to overflow() will return true).
2015-01-26Toggle SoftwareSerial interrupts when starting / stopping to listenMatthijs Kooijman
This prevents interrupts from triggering when the SoftwareSerial instance is not even listening. Additionally, this removes the need to disable interrupts in SoftwareSerial::listen, since no interrupts are active while it touches the variables.
2015-01-26Add SoftwareSerial::stopListening()Matthijs Kooijman
This allows one to explicitly stop a SoftwareSerial instance from listening, without having to make another one listening.
2015-01-26Add SoftwareSerial::setRxIntMsk()Matthijs Kooijman
This moves the interrupt mask enabling / disabling code into a separate method, so we can call it from multiple spots next.
2015-01-26Let SoftwareSerial::end also check against _rx_delay_stopbitMatthijs Kooijman
The current check is still always false when the old check was, but additionally it will not disable the interrupts when they were never enabled (which shouldn't matter much, but this is more consistent).
2015-01-26Let SoftwareSerial::listen() fail on invalid rx baud ratesMatthijs Kooijman
In this case, SoftwareSerial::begin will not have enabled the interrupts, so better not allow the SoftwareSerial instance to enter the listening state either.
2015-01-26Clear SoftwareSerial rx delay if no interrupt register is foundMatthijs Kooijman
Before enabling interupts, begin would see if the given receive pin actually has an associated PCINT register. If not, the interrupts would not be enabled. Now, the same check is done, but when no register is available, the rx parameters are not loaded at all (which in turn prevents the interrupt from being enabled). This allows all code to use the same "is rx enabled" (which will be added next).
