This seems like a good idea. Would you be able to add this as a PR to create a file in ./examples
, and also note which SBC this is designed to run on / has been tested on?

Sure, I'll make a PR later when I get my hands on the board to test it again. By the way, the SBC I tried this on was Orange Pi Zero
Hi. I'm sorry I haven't responded about this issue for a long time. I've thought about making the example + PR and I thought it would be good to make the example in gpio_cdev
instead of gpio_sysfs
since it is deprecated. But I tried adding the dependency in Cargo.toml
like this:
[package]
name = "gpiotest"
version = "0.1.0"
authors = ["vmasdani <valianmasdani@gmail.com>"]
edition = "2018"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
linux-embedded-hal = { version = "0.3", features = ["gpio_cdev"] }
And I got this error when building with cargo build
error: failed to select a version for `linux-embedded-hal`.
... required by package `gpiotest v0.1.0 (/home/valianmasdani/codes/rust/gpiotest)`
versions that meet the requirements `^0.3` are: 0.3.0
the package `gpiotest` depends on `linux-embedded-hal`, with features: `gpio_cdev` but `linux-embedded-hal` does not have these features.
Same goes when I change the feature to gpio_sysfs
the package `gpiotest` depends on `linux-embedded-hal`, with features: `gpio_sysfs` but `linux-embedded-hal` does not have these features.
When I them separately though, it's running fine and I'm able to blink an LED using set_value(value)
(I still use Orange Pi Zero):
[dependencies]
linux-embedded-hal = "0.3"
gpio-cdev = "0.2.0"
It works fine, but I ended up not being able to use embedded_hal
GPIO functions like is_high()
or set_low()
.
Am I missing something here or it's actually a bug/wrong documentation?
Greetings. I was kind of having a hard time getting the grasp of trying to use the digital GPIO pin. I worked it out in the end anyway, but I think it would be cool to add basic examples as simple as LED blinking, LED breathing, etc. like this:
