Matthijs Kooijman 03fac844a8 Move interrupt handlers into HardwareSerial class ... The actual interrupt vectors are of course defined as before, but they let new methods in the HardwareSerial class do the actual work. This greatly reduces code duplication and prepares for one of my next commits which requires the tx interrupt handler to be called from another context as well. The actual content of the interrupts handlers was pretty much identical, so that remains unchanged (except that store_char was now only needed once, so it was inlined). Now all access to the buffers are inside the HardwareSerial class, the buffer variables can be made private. One would expect a program size reduction from this change (at least with multiple UARTs), but due to the fact that the interrupt handlers now only have indirect access to a few registers (which previously were just hardcoded in the handlers) and because there is some extra function call overhead, the code size on the uno actually increases by around 70 bytes. On the mega, which has four UARTs, the code size decreases by around 70 bytes.		2014-01-16 16:59:06 +01:00
