Luminus SFT40 test

Emitter peaked at ≈10.2A in djozz's test. Not all emitters perform the same, and even if the differences are small with just one test we don't know where this one is at.

Setting the limit at 8.8A (in Convoy's ramping driver) is easy, just stick an R050 over the R005 sense resistor. With an R025, or two R050's in parallel over the stock R005, limit raises to 9.6A. Personally, I would stick an additional R050… or not care at all (whereas 10.2A is ≈2630 lemons, 8A is ≈2450, which is 93.156% of maximum output anyway).

Concerning the driver, at this point this regulated linear driver is my favourite, namely due to certain performance hindering shenanigans happened to the other “SST40” linear drivers at Convoy. Hardware wise it is the best one in every respect, although the stock firmware is somewhat limited and may not be everyone's liking.

If someone's going to develop a more common software for the MCU, I would be pleased. Also, porting some firmware from Toykeeper should be easy. :???:

Regards everyone

P.S.: This emitter in CRI95+ would be a blessing.
