Fair enough. I feel his mistake was simply that he did NOT use a smiley in that particular post. But he didn't and it's unfortunately not the first time he's expressed a view that physical violence would be an appropriate response. I therefore do not have a problem with the decision taken.

Re: Run Windows recompiled ARM binaries on raspbian with WINE [does not work]

It’s interesting how this thread has all the naysaying like bringing up Stratagus or saying “There is no WINE for non X86 systems”. It's basically people's ignorance, misunderstandings, preconceived but false notions of wine limitations. You'll find it elsewhere as well as here; people believing th...

Re: USB Serial ports on RPI 3

The "dongle" is included on the Arduino board. Traditional serially programmed development board - .-------...

Re: 3A+ usbboot/rpiboot

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 ...

Re: 3A+ usbboot/rpiboot

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)

There will be a blog post along later this morning to explain everything... That's good to know. It might be worth changing "base image" and "full image" terms to reflect the names being used. "Removed" and particularly "added" isn't entirely clear; "included" and/or "not included" would be better.

Re: 3A+ usbboot/rpiboot

The first question would be; is it (1) the 3A+ hardware not presenting itself as a USB bootable device or (2) rpiboot simply not recognising how the 3A+ presents itself ? I have a gut feeling that the BCM2837B0-based 3A+ may present a different VID/PID and description than the BCM2835-based Zeroes a...

XBox 360 Chatpad keypads are physically small, cheap, and have a good 'mechanical click' feel to them. They are UART serial interfaced using a proprietary protocol but can be wired direct to a Pi's UART. They can be made ASCII UART or RS232 serial or USB using a cheap micro,

Re: Power input monitoring?

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. Even a simple adc lying about unused on the board would help. The MxL7704 PMIC chip fitted to the 3B+, and I would guess 3A+, has tw...

Plugging in a wifi dongle is not an issue since there is no internet to connect to. Except when someone plugs in that dongle, connects to or from a mobile phone, and gets internet access that way.
