What's the modern documented assembler for 8051

I intend to program stc8g, a 8051 compatible, low cost microcontroller in assembly language instead of C. SDCC is a good compiler but its assembler SDAS is not documented (not able to find any documentation), so what's the alternate in Linux.

I though there would be many modern, well known assemblers targeting 8051 but I simply could not find one expect for SDCC and one from Keil (but I am not sure if that is free).

Any help would be appreciated.

IR receiver and transmitter packages

I have a bunch of IR LEDs and photodiodes and while sorting them it seems the 'packages' these come in are not consistent.

I thought the ones with clear dome have to be IR LED whereas one with darker dome (assuming for filtering) is the photodiode, but that is not so it seems.

Here are some the result of the sorting.

Here is a 3 mm photodiode (dark casing)

3mm photodiode (dark casing)

... and IR LED (clear casing)

3mm IR LED (clear casing)

Here is a 5 mm photodiode (clear casing)

5mm photodiode (clear casing)

... and IR LED (dark casing)

5mm IR LED (dark casing)

Are the color/filter of the case arbitrary, only exists to differentiate among the pairs?

Can Koreader save notes along with the highlights (PDF)?

I have seen that it's possible to save the highlights on to the PDF file (using 'write highlights info PDF' feature) but the notes are not exported. Is there a way to do that?

Using KOReader v2026.03 version
