I need to design a product based on the ESP8266 module,
However the Arduino compiler has native interrupt support for only TIMER and I/O .

Does someone has some tricky tip to add this feature to the Arduino IDE ?



Thanks in advance,
Andre.

https://github.com/muratdemirtas/ESP826 ... r/main.ino

Has someone used this one, or another functional code able to handle serial interrupts in Arduino with the ESP8266 core ?

- Thu Jan 18, 2018 6:15 am #73254 The Arduino libraries already use the uart interrupts to send and receive data via FIFO buffers.

These are in uart.c in ..... Arduino15\packages\esp8266\hardware\esp8266\2.4.0-rc2\cores\esp8266

The low level support is then used in HardwareSerial.c to give the normal access functions.

You could use your own to replace these if there is some pressing reason to do so.

There is also pretty good documentation on the UART hardware, registers, interrupts etc in 8E-ESP8266__Interface_UART__EN_v0.2.pdf A google search will find where to get it.
