#CH340

Also I had a problem connecting up to my Elegoo Neptune 3 #3DPrinting printer which uses a #CH340 but this article on removing brltty sorted that out for me :)

Sadly updating to Ventura didn't solve my #CH340 problem. This ATmega4808 board with the CH340K is still not visible beyond the system_profiler view (doesn't show up in /dev).

Maybe in Sonoma, but I'm not going that far.

Next approach is to install the latest Chinese device driver for it, but on an older machine that doesn't use the Apple driver: "DriverKit-AppleUSBCHCOM" which seems to be the culprit.

I've had some luck with that #ATMega4808 board as far as getting an #ArduinoNano wired up as programmer and using the #JTAG2UPDI code to push the a 4808-friendly bootloader onto the device.

A problem though has brought me back into the nuances of the #CH340 serial chip world, which I had hoped I was done with yrs ago.

Seems maybe older MacOS versions have probs with CH340K vs G vs other variants.

I'm still on BigSur though, so perhaps this is reason to increment up to Ventura.

Bit of a development this morning! This is #RISC_OS on the #raspberrypi 400 talking to a clone #8bit #Arduino Mega & running #ProjectRIO / #tinyBASIC via #CH340 USB serial driver... this might actually have a use case!

The programming cable for my #Cotre #CO04D showed up the other day, a holiday project.

The programming cable I have has a #CH340 chip in it, and my Windows machine is a "Windows on Arm" system (sigh), so I have to track down and figure out how to install the proper serial drivers. (Or, I need to borrow a proper x64 Windows machine to program it, that might be way easier.)

My reference info still comes from https://jhart99.com/better-cheap-dmr/ (who reports that a CH340 based setup worked for him)
