Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
libopencm3
- Open source ARM Cortex-M microcontroller library
-
Setting up a good dev environment without recreating the world
Some of the vendor IDEs have the option to generate makefiles for a project. Depending on the processor, you could also opt out to a different system. A lot of the popular cortex-m stuff is supported by libopencm3.
- Is there a command line process for ST embedded devices?
-
Looking for someone interested in designing a HAL
You can also look at examples of HALs such as - libopencm3 (Though this is Cortex only) - RIOT OS (though this requires an RTOS)
- how come there aren't any open source drivers for MCUs?
- Is there a database of peripheral implementations for different STM32 MCU parts?
-
Portable driver libraries or HAL that supports Atmel SAM targets?
Yeah by the looks of it I am going to have to expand my project do creating a portable driver interface as well. Abstracting hardware interfaces to create portable code is fairly common in embedded development. For example, libopencm3 does this and has great support for STM32 parts but very limited support for SAM parts.
-
How can i implement USB interface for an embedded flight controller to enable serial prints, parameter changes AND reading data from an SD card?
TinyUSB or Libopencm3 are probably your best options (although check they support the SAME70).
-
Which uC has the most flexible, feature-packed SPI peripherals?
that is fair. SPI isn't very portable across Arm cpu vendors because all peripherals are vendor specific, i.e. the registers will differ a lot and APIs reflect that. Finding common ground is hard unless using specifically designed portable libraries like https://github.com/libopencm3/libopencm3
- Code organization and modularity
modm
-
Looking for well written, modern C++ (17/20) example projects for microcontrollers
Have a look in the modm.
-
how come there aren't any open source drivers for MCUs?
Something like https://modm.io ?
-
C++ for embedded - low level applications
On my way i found modm.io which can generate a HAL for (a lot) STM32 controller. They use C++17 and have lots of examples for different controllers the STM32 F4 Disco examples show some applications.
