Cannot import "i2c" from remote dependency, possible if local build #57

Closed litchipi closed 2 years ago

litchipi commented 3 years ago

I got a code with this import line: use esp_hal::i2c::{self, Error, I2C}

In the Cargo.toml file: esp32-hal = { path = "./esp32-hal/" } (github clone in local dir) -> works fine esp32-hal = "0.2.0" -> "could not find i2c in esp32_hal"

You can grab my full code here: https://github.com/litchipi/esp32rs/blob/oled_simple/src/oled_simple.rs It's basically a copy-paste of the example given in the hal for now.

(PS: I tried to create my own example, but the libs used in the example of the hal are outdated and the new versions doesn't work anymore. Should I open another issue for this as well ?)

The I2C feature is in the github repository but not on crates.io. I am not a maintainer but I believe the feature is not mature enough to be released. There is at least one todo in the i2c.rs file.

You could use the github repo in your Cargo.toml until the feature is on crates.io: esp32-hal = { git = "https://github.com/esp-rs/esp32-hal.git" }

The 0.3.0 now includes the I2C module :)
