Doesn't work on ESP32-C3

[robertgregor]

Tryin to use it in ESP32-C3, but it do errors like:

ELF file SHA256: 088975f91042702a

E (1379) esp_core_dump_flash: Not enough space to save core dump!
E (1384) esp_core_dump_elf: Failed to prepare core dump storage (257)!

Seems, the issue is RMT channel error?

@robertgregor any luck with solving this issue?

FYI I am using this one (RMT based also) : https://github.com/junkfix/esp32-ds18b20
Not tested under C3 (supposed to work), only tested on C6 and esp32dev and others.
Made a simple wrapper around: https://github.com/mathieucarbou/MycilaDS18

I haven't looked into this yet. It may have something to do with the updates done the the RMT HAL.
