if the board provides a microcontroller in addition to the chg340 usb to serial chip, it could be programmed (my first email suggested using an arduino) to do the serial to spi conversion
You could probably re-program it - but why since it's already coming with fully implemented solution?

Re: How to use nRF24 via CH340T serial-to-USB converter?

LOL - too much disinformation floating here... spi requires a clock signal, which is NOT available on a serial port. Of course it does and µController on CH340T board will provide one. I was never saying that TX and RX lines from serial are directly connected to MOSI and MISO lines :P Of course you ...

Since it seems nobody else reported: https://forum.freecadweb.org/viewtopic. ... 8&start=80
it seems that Alex has found (with help of others) winning combination how to build FreeCAD (the latest from master - 0.19) that runs on Pi4 (Buster).

Re: How to use nRF24 via CH340T serial-to-USB converter?

Huh - my previous post has gone missing. Never mind - gist was as following: I think (*think*) serial here is used instead of SPI - actually adapter sends everything it received from serial to SPI relaying back all (in turn) received back from SPI(*) Also, one of control serial lines CTS/RTS or DTR/...

Re: How to use nRF24 via CH340T serial-to-USB converter?

I'm currently (I mean - actively - today!) using nRF24L01 connected directly to SPI of RPi. With Raspberry Pi you really don't need USB adapter. There are plenty of other examples all over the internet :) BTW Right now on my desk I can see 4 nRF24L01 connected - 2 to 2 Raspberry Pis and 2 to ATmega3...

Some improvements have made it to the release MESA libraries already, there are others still to work their way through the system.
Looking forward giving it a try when they get released, too. This one (very imprecise measurement) brought almost (or over!) 50% speed up for pixel manipulation.

If you don't need to copy root to your image (on HD) - even better - you just need to update `/boot/cmdline.txt` and that's all!

Interesting (and accurate) set of instructions.

Mine was pretty much vanilla Raspbian + extra packages I installed when needed. And I just didn't pay attention to what I was installing. Sorry :)

OK, good point about 32bit, so systemd is now off topic for this thread. Start a new one in Off Topic to complain about something that works.
