Add example code for generating USB key events and mouse events

3

I would like to use my Teensy4 to generate keypresses and mouse clicks. The C API is discussed at https://www.pjrc.com/teensy/usb_keyboard.html but I can not find an example in in the...

first attempt at AVR architecture support (needed for arduino cross-compiling)

1

When using `bindgen` to generate `bindings.rs` for Arduino libraries, we can not rely on the standard `ctypes_prefix()`. The most common replacement is `cty`, but cty fails to compile on the...

the SPI implementation does not support channel select pins other than pin 10 (PB2)

2

I have a project with an Arduino Uno, an ethernet shield (v1), and an OV5642 SPI/I2C. There are actually 3 SPI peripherals in this setup, because the ethernet shield includes...

This is a modified version of https://github.com/Rahix/avr-hal/pull/259 . Based on feedback from Rahix, it includes the `avr-portable/` crate, but only the `arduino-uno` and `arduino-mega2560` examples are modified to show calling...

make serial port, ADC, and SPI examples portable across targets

5

extract the serial port example into a portable function that demonstrates how to declare the serial port using generics such that it will compile on multiple targets. I think folks...

There is a bug in LLVM regarding MOVW being translated into a pair of 8-bit register moves which could malfunction if the register pairs overlapped. This was discovered while troubleshooting...

include a serial and adc object to the template

1

While the focus of this template is mostly providing the AVR scaffolding, I feel that the main.rs could benefit from a couple of more examples of how to create objects...

This bug report has an example repo to aid in reproduction of the problem: https://github.com/mutantbob/bindgen-malfunction It does not seem to malfunction when generating in the native environment, but instead malfunctions...

How can you make rosimagesrc generate an End Of Stream event to eventually end the pipeline?

2

I am experimenting with the `rosimagesrc`. I am playing a bag file that someone else recorded. I am using the pipeline ``` gst-launch-1.0 rosimagesrc ros-topic=/cam0/image_raw ! videoconvert ! x264enc !...

how do I preserve the ROS timestamp?

3

I have a bag containing test data that we want to route through gstreamer. There are two camera streams and an IMU stream. I wrote a very short python script...
