Re: Pi4 as Desktop computer

I noticed you used the McMojave KDE plasma theme. I used that for a while. I followed all the steps you took to get the animations working perfectly. Runs great.

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.
Do not envy you (for moderating this forum). It is odd nobody mentioned USB booting in conjunction with 32/64bin apps, yet. :roll:

Re: KDE Plasma on Pi4B4.

I'm using it on daily bases without issues. All on Raspbian. On 4K monitor with resolution lowered to 2560x1600.

Cannot comment on performance as I have nothing to compare it with :( I would say it is more than usable, but that's subjective.

Re: How to use RS485 Shield with Raspberry Pi

Wait - RS485 is current loop version of RS232 which is seen as ordinary serial or RPi (pins 8 and 10 - GPIO14 and GPIO15). To use serial you need to make Linux stop wanting to use it for console (https://www.raspberrypi.org/documentation/configuration/uart.md) and you can access it through /dev/seri...

2S means 2 in series, which gives you 7.4v nominal, 8.4v full... Yes, but don't forget protection strips to balance the load. You should not put 2 LiPo cells in series without that.

Can you try using i2c3 on GPIO2&3?
In config.txt comment out dtparam=i2c_arm=on and add the line dtoverlay=i2c3,pins_2_3 . The corresponding device node is /dev/i2c-3.
Yes, clock stretching seems to work correctly on IC2-3.
That's good to know. Thanks :)

Re: running the system (a pi4b) off of ssd, will it give speed improvements?

Due to RPi size I would recommend M.2 with an adapter. Also, there are B, B+M and M key M.2 adapters. It seems that B and B+M are cheaper than M key only. Also, M key are faster but I am not sure if you're going to see any improvements due to USB3 (and RPi USB3) limitations.

Java is very versatile object oriented language that can do many things and falls in very similar category as Python.

So, answer is: yes.

All you have to do now is to learn it. Internet is full of resources, examples and sites where you can even learn it online, do online courses and such.
