* support psram in DmaTxBuf * add example that sometimes works :-( * fmt * cleanups * allow chunk_size upto (including) 4095 * this test is passing for me now * remove chunk_size and compute based on block_size * return error in `prepare_transfer` if psram is found on non-esp32s3 add `dma_tx_buffer` macro * missing parens * changelog * default 4092 for esp32 & fmt * no errors anymode * use block_size is_some to flag invalid psram in prepare_transfer * drop block_size from macro, the buffer allocation was not being aligned - its not needed for dram anyway. * missed macro example * use defmt::Format that decodes owner like Debug * fix typo * DmaTxBuf: its an error if buffer is in psram and block_size is none * DmaTxBuf: its an error if buffer is in psram and block_size is none * update for PSRAM feature changes * address alignment comments add simple test * fmt * better alignment test * revert alignment test --------- Co-authored-by: Juraj Sadel <juraj.sadel@espressif.com> |

esp-hal
Bare-metal (no_std) hardware abstraction layer for Espressif devices. Currently supports, to varying degrees, the following devices:
- ESP32 Series: ESP32
- ESP32-C Series: ESP32-C2, ESP32-C3, ESP32-C6
- ESP32-H Series: ESP32-H2
- ESP32-S Series: ESP32-S2, ESP32-S3
Additionally provides limited support for programming the low-power RISC-V cores found on the ESP32-C6, ESP32-S2, and ESP32-S3 via the esp-lp-hal package.
These packages are all no_std; if you are looking for std support, please use esp-idf-svc instead.
If you have any questions, comments, or concerns, please open an issue, start a new discussion, or join us on Matrix. For additional information regarding any of the crates in this repository, please refer to the relevant crate's README.
Note
This project is still in the relatively early stages of development, and as such there should be no expectation of API stability. A significant number of peripherals currently have drivers implemented but have varying levels of functionality. For most tasks, this should be usable already, however some more advanced or uncommon features may not yet be implemented.
Getting Started
For information relating to the development of Rust applications on ESP devices, please first read The Rust on ESP Book.
For information about the HAL and how to use it in your own projects, please refer to the documentation.
