Re: Raspberry Pi 3B+ Bullseye Performance is Unacceptable

The B+ is a 7 year old Raspberry Pi, and it was not cutting edge stuff back then. The Desktop was much lighter weight way back when. After the 2 and especially the three, it Chromium took over as the browser and like Firefox etc uses a lot more resources then you need for most simple webpages. Eithe...

Re: Raspbian / Raspi OS updates -- on releases and kernels

Ignore the kernel, that's the core bit that everything else talks too. It brings driver updates and ways of talking to the hardware etc. It's not about the programs/applications you run. You can personally run any newer kernel on you older RaspberryPi OS, but you'll have to build it yourself. You're...

Re: Idiots Guide to Uputronics GPS HAT/Pi 4 please!

If you keep getting odd bits of data.
You could try turning off Bluetooth if you don't use it (in config.txt).
You can then use /dev/ttyAMA0 (it will still be seen as /dev/serial0 if you are using that).
Which is the full fat UART not the miniUART that is on ttyS0

Worth a test at least.

Re: Estimating benchmark performance

Though a couple of quid/euro/.. will allow you to run a few tests of your code snippets to benchmark, then you can build up your own comparisons and weight as you need for future use.

i.e Just buy a Pico or other RP2040 board ;-)
And see how it goes from there.

Yes I can do it myself, but factory Wave soldering will be a far cleaner/neater job than what i can do!
The release blog said no, unless sometime soon is middle of next year or even later.

Given the Pi3 was 1.2GHz in the first place and didn't over clock extremely well*.
