[rusty_attiny13a]

(A weekend experiment using the Rust programming language on small attiny13a microcontrollers.)

Our package provides a minimal but functional SDK for use on ultra-small microcontrollers such as the ATTiny13A. The package implements a variety of software buses, including UART and I2C, which provides the ability to connect and interact with various peripheral devices. The library also includes experimental ultra-lightweight support for output to SSD1306.

The aim of our experimental project is to showcase the use of the Rust programming language on ultra-small microcontrollers like ATTiny13A. We aim to demonstrate that even on such constrained devices, Rust can be an effective and flexible development tool.

1. Supports I/O at a specified speed using a parity bit (write-only bit).

2. Delays are implemented only in software (the timer is not used).

3. Supports recording to multiple I/O ports simultaneously.

4. Support for burst or single-byte reads.

examples: uart, uart_rw, uart_rw_debug, uart_rw_onebyte

env:

Launch example:

UART_BAUD=115200 UART_PARITY=0 cargo run --release --example uart

1. Support for the I2C bus with setting the desired frequency (it was not possible to set the exact frequency due to flash memory limitations, for example, at a frequency of 400 kHz we get +-355 kHz at the output). (100khz/400khz/800khz/... also supported.)

2. Support for the ACK bit, and with it the ability to determine the success of a transmission.

i2c_scan:

A classic example of i2c bus scanning.

UART_BAUD=115200 cargo run --release --example i2c_scan

print_logo, print_u16counter, flip:

cargo run --release --example ssd1306_x32_counter
