No longer compiles after the update on Arduino IDE

[emanuelelaface]

After the latest update of Arduino IDE no example compiles anymore with the error Compilation error: 'TIMER_BASE_CLK' was not declared in this scope.
I think the reason is that it changed the API for the interrupts in the Arduino-ESP32 since version 3.0.0.

hi,

indeed esp-idf timers have been migrated to GPTimers

currently the library supports two types of timers:

• software timer
• idf 4.x + hardware timer

and now it needs to be modified to handle a third type of timer:

• idf 5.x + GPTimer

I tried a couple of times to follow the migration guide and only managed to get headaches, some breaking changes in the new timer concept prevent the usb main task to be called from an alarm callback function and I don't know well enough the new paradigm to find a solution to that problem.

so unless a good soul with enough skills provides help, support for arduino-esp32 3.x won't happen any time soon
