trait DrawTarget is not implemented for ... Ssd1306 / esp_idf_hal::i2c::* about esp-idf-hal HOT 2 CLOSED

embedded-hal and embedded_graphics are moving a lot. We in esp-idf-* support the latest embedded-hal-1.0 rc releases + 0.2.x release of embedded-hal.
While i never played with the ssd1306 around, often these problems come from version-mismatch of the e-hal versions used in the driver and esp-idf-*. and similar in the e-graphics crate.
To get a better overview check out cargo tree and look for versions of embedded-hal + embedded-graphics that are pulled in. You can grep for specific crates with cargo tree -f "{p} {f}" | grep <crate-name>
For related help you can also check out both matrix chat-rooms around rust esp-idf and especially the embedded-graphics room

This growing pains should hopefully be gone, when the hal's reach stabilization and most drivers uses this versions.

The ssd1306 needs e-hal 0.2-compatible i2c driver, which the HAL crate does implement. You are likely using the wrong versions of display-interface or embedded-graphics-core. Please check the Cargo.toml of the ssd1306 crate as for the exact versions of these crates you have to use.
