ESP32 UART RXINT interrupt is missing

Hello FC Team,
I`m missing the RXINT Interrupt function inside the ESP32 command interrupt icon.
I´ll compare this with the PIC-8 command interrupt icon. There you have a choice to select this important function.
Is a RXINT possible with the ESP32??

Hi Dvcam99
Interrupt is working on my esp32. I used A3 for rx pin
and
GPIO3 for the Interrupt
regards
Stefan

Hi Stefan,
many thanks for the feedback.
Yes I saw this possibility too but you can trigger only at the rising or falling edge of the input.
I`m looking for example for incoming received byte trigger. Same like we have in the PIC8 section.

UART Rx interrupt is now done, it will be available from the auto update system sometime soon
Note that UART receive is buffered, so interrupt is not as necessary on ESP32 as other (non-RTOS) devices

Hello Leigh,
very good news!!
I`ll check it out asap it is available.
Regarding the ESP32 buffer, do you know how many bytes it can store??

A quick Google seems to indicate 128
