Supports the ESP32, ESP32-C2/C3/C6, and ESP32-S2/S3. Optional exception and panic handlers are included, both of which can be enabled via their respective features.
Please note that you need to force frame pointers (i.e. "-C", "force-frame-pointers", in your .cargo/config.toml)
You can get an array of backtrace addresses (currently limited to 10) via arch::backtrace() if
you want to create a backtrace yourself (i.e. not using the panic or exception handler).
When using the panic and/or exception handler make sure to include use esp_backtrace as _;.
When using this together with esp-println make sure to use the same output kind for both dependencies.
(Or don't specify the output for esp-backtrace)
