The patches required to use C++ STL

5

In Arduino micro/leonardo Pin HWB is not exposed as digital pin

2

In the [Atmega32u4 Pin Mapping](https://www.arduino.cc/en/Hacking/PinMapping32u4) PE2 is documented as HWB so the expected behavior would be the user to be able to use it as a digital pin. In the...

Don't waste RAM in the low-level TWI Wire driver

2

This originated on MCUdude/MiniCore#245 Since `twi_readFrom()` and `twi_writeTo()` are both blocking functions, there is no need to allocate a special `twi_masterBuffer`. Doing so wastes valuable RAM, uses extra time to...

USB Serial on 32U4 stops incrementing Serial.available() if serial buffer has ≥2 bytes in it and more are received

4

After some investigation, I was able to narrow down my code to the minimum that reproduces the bug, then I added some code that helps me locate where it is....
