ESP32 + SSD1306 - called `Result::unwrap()` on an `Err` value: BusWriteError

Postby 35p32fan » Sat Dec 16, 2023 12:32 pm

Hi,
found the Source Code at: https://github.com/andy31415/rust-esp32-c3-demos

Compile works, but did not run on my ESP-WROOM-32D

Console Output:

Code: Select all

ELF file SHA256: 0000000000000000
