Jacdac firmware library

This library implements platform-agnostic aspects of the Jacdac protocol. It's meant to be included as submodule, and use the build system of the parent repository.

It's currently used in the following projects:

• https://github.com/microsoft/devicescript
• https://github.com/microsoft/jacdac-stm32x0 (which has some better docs on building)
• https://github.com/microsoft/devicescript-esp32
• https://github.com/microsoft/devicescript-pico
• https://github.com/microsoft/devicescript-stm32

This library is part of Jacdac Device Development Kit.

Adding new services

It's best to start from an existing service, and do a search-replace (eg., servo -> rocket)

• services/servo.c has a simple example of registers
• services/buzzer.c has a simple example of how a command is handled (in buzzer_handle_packet())
• services/thermometer.c is a very simple sensor
• services/power.c is a more involved sensor (with custom registers)

Once you add a service, make sure to add its *_init() function to services/jd_services.h.
