embedded-hal implementation for Rust on ESP32 and ESP-IDF
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:11 reviews, 10 commits, 13 PRs in 2 months
Contributions summary:Ronen primarily contributed to the `esp-rs/esp-idf-hal` repository, which provides an embedded-hal implementation for Rust on ESP32. Their work focused on enhancing the hardware abstraction layer (HAL) for the ESP32, fixing bugs, migrating to newer embedded-hal versions, and adding new features such as HPoint control for LEDC. Several commits involved modifying the UART and I2C drivers to support single-wire communication and adjusting code for changes in the underlying ESP-IDF. The user also contributed to examples showcasing the HAL's usage with various peripherals like PWM, RMT, and SPI.
