Re: Raspberry Pi Archiver

My RPi 2, RPi Zero, are on my wired/WiFi network. I setup SMB file sharing on the RPi's. Gave them the username/password for their own logins to my small Network Attached Storage (NAS), on my LAN. Each RPi can then read/write files on the NAS for their login. And vice-versa, a PC on the LAN can acce...

Re: Want solderless headers for the Pi0?

Solderless header pins. I have some.
They have springy metal on one end. Press these into the PCB holes and you have a header pin row that doesn't have to be soldered.

They're hard to find now. Mine came from Sparkfun.com
mill-max makes some other types but they're costly

Re: Should we promote an OO approach?

OO and procedural programs seem to me to be different beasts.
C, C++, Python, Java, javascript, etc. are all procedural languages. OO or not.

Non-procedural languages are exemplified by Prolog. And arguably, SQL.

Re: Elevator project

An elevator controller using an RPi for a University term project makes sense.

Certainly not one for commercial use.

Re: Is there a way to boot the Pi 2 without HDMI connected?

I've long used VNC on RPis for headless operation.
VNC server on RPi.
VNC client(s) on PC on your LAN, or if you dare, through ports opened on your router and across the Internet.

Re: Open UART writes 0xff

Likely the driver configuring the UART (baud rate, modes).
An attached device has to tolerate such and have a means to ignore or restart.

Re: programming pi with assembly language

Learn assembly language on a smaller, simpler system - one without a memory management unit (MMU). Really need simple hardware to begin this learning with. Maybe an Arduino but it's an 8 bit AVR and has an odd architecture, as do PICs. So maybe a small ARM7 or ARM cortex M3 with way less than 1MB, n...
