# [pimoroni-servo2040] - Board Support for the [Pimoroni Servo2040]
|
|
|
|
You should include this crate if you are writing code that you want to run on
|
|
a [Pimoroni Servo2040] - a standalone servo motor controller for up to 18 servos
|
|
and 6 sensors.
|
|
|
|
This crate includes the [rp2040-hal], but also configures each pin of the
|
|
RP2040 chip according to how it is connected up on the Servo2040.

|
|
## Using
|
|
|
|
To use this crate, your `Cargo.toml` file should contain:
|
|
|
|
```toml
|
|
pimoroni-servo2040 = "0.1.0"
|
|
```
|
|
|
|
In your program, you will need to call `pimoroni_servo2040::Pins::new` to create
|
|
a new `Pins` structure. This will set up all the GPIOs for any on-board
|
|
devices. See the [examples](./examples) folder for more details.
|
|
|
|
## Examples
|
|
|
|
### General Instructions
|
|
|
|
To compile an example, clone the _rp-hal_ repository and run:
|
|
|
|
```console
|
|
rp-hal/boards/pimoroni-servo2040 $ cargo build --release --example <name>
|
|
```
|
|
|
|
You will get an ELF file called
|
|
`./target/thumbv6m-none-eabi/release/examples/<name>`, where the `target`
|
|
folder is located at the top of the _rp-hal_ repository checkout. Normally
|
|
you would also need to specify `--target=thumbv6m-none-eabi` but when
|
|
building examples from this git repository, that is set as the default.
|
|
|
|
If you want to convert the ELF file to a UF2 and automatically copy it to the
|
|
USB drive exported by the RP2040 bootloader, simply boot your board into
|
|
bootloader mode and run:
|
|
|
|
```console
|
|
rp-hal/boards/pimoroni-servo2040 $ cargo run --release --example <name>
|
|
```
|
|
|
|
If you get an error about not being able to find `elf2uf2-rs`, try:
|
|
|
|
```console
|
|
$ cargo install elf2uf2-rs
|
|
```
|
|
then try repeating the `cargo run` command above.
|
|
|
|
### [pimoroni_servo2040_rainbow](./examples/pimoroni_servo2040_rainbow.rs)
|
|
|
|
Animates a rainbow wheel on the Servo2040's six on-board LEDs in sequence.
|
|
|
|
|
|
|
|
### [pimoroni_servo2040_pwm_servo](./examples/pimoroni_servo2040_pwm_servo.rs)
|
|
|
|
Moves a micro servo connected to pin Servo 1 on a Servo2040 board using the PWM
|
|
peripheral.
