Get elapsed time since some instant in embedded rust
I started making a program in rust, and I want to be able to get the elapsed time since some instant. Here's how the std library does it.
use std::time::{Duration, Instant};
use std::thread::sleep;
fn main() {
let now = Instant::now();

Enforcing trait implemented only on given type size in Rust
For embedded/IO use case in Rust, I need to build a lib to receive/transmit messages using a small fixed size buffer (must not exceed it). The messages themselves will be defined by the user of the lib.
Is there a way to define a Rust trait or a…

Set alternate mode for stm32 rust HAL
I want to set alternate mode for AP10 of stm32f411 by rust HAl. My code looks like this:
let rx_pin = gpioa.pa10.into_alternate();
But it has multiple impl:

Embedded Rust & Embassy | Analog measurement - ADC & DMA | STM32F7
My setup:
The signal is connected to the analog input of the STM32F767.
ADC sampling rate should be at least 192kHz because input signal frequency is between 1Hz and 40kHz.
Also STM32 connected to the client via ETH port (UDP protocol).
My…

rp2040_hal I2CPeripheralEventIterator usage
Coming from C# and the .NET world, I needed to go bare metal with some IC (in this case the rp2040), and choose Rust based on every comment that I saw for the language.
Until now, I been able to easily use gpio, I2C as master, but my usage case, the…

Modifying a specific memory address in Rust
I declared pointers (memory addresses) and I am able to read values like that in Rust:
let psram = 0x60000000 as *const u32;
let psramh = 0x60000000 as *const u16;
let psramb = 0x60000000 as *const u8;
let psram0 = unsafe…
