Description:

Currently, I got UART interrupt working fine. I have created new class to inherits HardwareSerial then overrides begin() to enables interrupt routine. As my understanding from ESP32 docs, when registered interrupt isr, its override default isr handler. This means the Rx HardwareSerial that relies on IDF's API (eg. read, available, etc.) will be unusable, need to handles from isr by user. So, I have override HardwareSerial functions to points to a new create buffer, queue that handles the data from isr (likes an old implementation in 1.0.6).

I have take a look at uart-event but if i want to unpack my serial packet per byte, i think isr still the way to go. correct me if i misunderstood.

Is there any other solution to workaround this if i still want to use HardwareSerial functions (some libraries that based on default HardwareSerial functions) while using UART interrupt.

Cheers,
