Talking Tock Week 8by Amit
This is the eighth post in a weekly series tracking the development of Tock, a safe multi-tasking operating system for microcontrollers.
We’ve sent out for production what we think is going the final version of imix. It includes fixes to a variety of small electrical issues we found after porting more of Tock to it. The final revision Will cost around $90 to produce at medium-scale (100s) and we plan on making these available at cost (plus whatever overhead) sometime in the next couple months.
Drivers, Capsules and Interfaces
@bradjc merged several of their drivers from signpost upstream, including:
SI7021 temperature and humidity sensor
FM25CL FRAM storage
@bradjc’s changes to the ADC are merged
We added an LED and Button driver similar to the GPIO driver to allow cross platform applications to use whichever buttons and LEDs are available.
@KBaichoo fixed a gnarly bug in the SAM4L SPI controller capsule.
Interprocess communication (IPC)
@alevy opened a pull request to begin merging work on an interprocess communication model based on the existing system call interface.
