Controller
A Controller (in the context of the LCPF) is an embedded controller running device that uses Devicess to sense things in around it and produce effects which change over time.
Practical details
LCPF is not intended to support any and every embedded controller out there. The LCPF has a specific list of supported Controllers, and only contollers on that list will give you the full benefit of the LCPF. Adding support for new controllers is not necessarily difficult (for the LCPF development team) - it can be a matter of minutes to āconfigureā support, but actually testing and making sure that a new controller works as expected might take a while.
There are a number of requirements that a new controller must meet to be considered for LCPF support:
- It must have active CurrentPython support
- LCPF is built on CircuitPython, so this is a must
- It must have sufficient resources (CPU, RAM, Flash) to run the LCPF. While the
minimums are still being determined, and may vary depending between
different boards, the following guidelines will likely apply:
- 2MB Minimum RAM (some of which may be PSRAM).
- Unfortunately this rules out a lot of the available CircuitPython boards
- Reducing that to around 512MB, which is about the max for most types of board without PSRAM, is probably not going to happen. Doing so could make it fairly easy to set up a project that runs out of RAM - especially with WiFi/WebUI suppport
- 2MB Minimum RAM (some of which may be PSRAM).
- It should support a ShieldStandard
- While not absolutely required, this greatly increases the flexibility and options available to LCPF users for a Controller.
