The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

A Single-Cycle 64-Bit RISC-V Register File
There are some MCUs that use RV32E also - the CH32V003 [0] comes to mind.

2x 2538 SMD LED for the key switch. How do I make this workout?
Higher interest in the mechanical issue. Kailh box aren't made for 5050-equivalent-sized LEDs so the best I can come up with is placing them on a daughter board with some distance and just accepting losing some light. Probably will use a low-cost microcontroller and R2R leader (current sink) to make them addressable. Alternatively, make use of the 11 bit PWM and LC filter while the ADC forms the feedback loop. Currently unsure if I go with WCH CH32V003 (https://github.com/openwch/ch32v003) or Padauk MCUs. A couple of kHZ PWM should be fine but if I make a PCB I might as well just go all in with PWM-free.

CH32V003 PWM
Do you have the document, CH32V003DS0_EN.PDF ? Have you done a "git clone https://github.com/wuxx/nanoCH32V003.git", to get the demo package from github? So far, I can't see any problems with your code, although I haven't figured out how Channel 2 of Timer 1 is specified, but I'm totally new to this processor. I'll keep looking...
