Something on F1C100s by piotr_go

To avoid asking the author on PW, @piotr_go let me dig up the thread.

- How did you implement the RGBTTL? I'm mainly asking about the backlight - as far as I can see each display requires different voltages, as the rest, if I see correctly directly goes out to the FPC socket. This connector could be problematic from an RFI perspective. Do you happen to know anything more about the guts of the IC? Does driving the lcd set the slew rate accordingly?
- Assuming the use of CSI (camera), do you associate the possibility of a simultaneous LCD TTL? There perhaps one data pin is shared with the CSI pin. Does this mean either one or the other or is it possible to reconcile both peripherals?
- I'm thinking of some kind of signal conversion to TMDS, on the wallpaper I have SIL504CMG208 (I2S audio but here may be the problem the same as with CSI) and TFP410.

I'm asking purely hypothetically, I'm building projects as a hobby but I don't want to ignore any issues. It is not enough for me that somehow it works .

I originally wanted to make a remote control for some small vehicle on this IC. Assuming using a video codec and e.g. LTE on USB, it could theoretically push video there.

However, I decided to build some sort of breakout to protest both TV and LCD interfaces. I don't want a ready-made one either, as I intend to familiarise myself with the hardware.

Inverter with current stabilisation. I can change the measurement resistor if necessary.

I don't recall any slew rate settings. Maybe they were cut from the PDF, maybe they weren't.

The camera did not interest me at all.

I dealt with it over 4 years ago. I don't remember everything exactly anymore.
I was planning to switch to something newer (Cortex Ax) with more RAM so I let the F1C200s go.
