Re: My own Retro homecomputer called RhoCoCo

The Zeta SBC V2 uses a 74LS670 for this very purpose. The Zeta's a nice machine, but perhaps has too high a chip count for what you want to do. Thanks for that link. It's good to see I wasn't entirely mis-remembering things from four decades ago! The discrete chip count can be high when other memor...

Re: RP 3 B+ Hardware is not working

I checked with multi-meter, 1 pin of gpio it shows 0v (not showing 3.3v). If pin 1 of GPIO header is giving 0v, then the regulator chip has died, possibly because there was at some point a short-circuit. It isn't possible to fix it. You will have to replace the Pi. If the regulator has died it may ...

Re: My own Retro homecomputer called RhoCoCo

The 74LS670 might be something worth looking at. That's a single chip 4x4 dual-port register file which allows 128KB to be mapped to a 64KB address bus in 8K pages, 256KB as 16KB pages, 512KB as 32KB pages.

I'm surprised the 3A+ didn't use a micro USB socket same as on the Zero and Zero W except with some protection against being back powered. I presume that was to make it a drop-in replacement for the A+. I think that decision is right; it's an upgraded A+, not an upgraded Zero / Zero W. It would be ...

Unfortunately on the PI 3A+ the OTG pin is connected to ground such that it will default to host mode. Then shouldn't that allow USB booting? Yes, and that's fine. It's device boot mode which is the issue. It's all a bit complicated. There are two different USB modes - Host mode - Where the Pi's US...

Re: How to filter out letters from strings and only keep numbers

One brute force approach would be -

Code: Select all

def PullOutNumber(s):
  o = ""
  for c in s:
    if c in "0123456789.":
      o = o + c
  return o
  
sInput = "temp = 36.6C"
sNumber = PullOutNumber(sInput)

Is there any mechanism built into the default RPI 3series that could be used or abused to monitor the actual input voltage at the power input socket? Potentially yes.
