Try pseudo-code :
Open door
gpio write 6 0 # Disable motor
gpio write 4 1
gpio write 5 0
gpio write 6 1 # Re-enable

Close door
gpio write 6 0 # Disable motor
gpio write 5 1
gpio write 4 0
gpio write 6 1 # Re-enable

FreeCAD 0.18 crashes on a Pi 4B 4G - Buster - 32 or 64 bit kernel. Same result on a Pi 3B+
From the opening screen...
Selecting 'File - New' or 'File - Open' results in a complete crash of the program (back to desktop).
FreeCAD 0.16 on Stretch OS runs ok on a Pi 3B+.

Thanks for the advice, however I think I am not making myself clear enough! I have used apt, apt-get AND synaptic. However the mirror site (raspbian.melbourneitmirror.net - 202.124.241.168) is not providing the software that apt requests, even though I can ping the site ok (while it is NOT sending m...

Using apt-get I am having big problems with my mirror site here in Melbourne Oz
Where is this configured, so that I may try other mirrors. Goggle wasn't much help
(although I never seem to be able to ask the right questions!)

Interesting news article... http://www.abc.net.au/news/2016-11-01/spinach-used-to-detect-explosive-materials/7983426 Which naturally leads to... A new version of the PI is coming, 50% larger in size. The extra "real estate" used for surface mount spinach! Still designing the water-cooling ...

You can try some code like this... /******************************************************************* Defined elsewhere... unsigned int PERIPH_BASE; // Base address to add to Register offsets #define BASE_1 0x20000000 #define BASE_2 0x3f000000 // RaspberryPi B2 The 'else' code works out the model ...

Thanks for sharing your work with us. A truly amazing, almost Pi-fect, job. Best regards.

Just an update on busybox. A good exercise (in futility) but basically not worth the effort!
After replacing 200+ commands with busybox I saved only 10 MB of disk space.
Therefor busybox is probably only useful for SOCs with limited onboard flash memory.
Thanks again for the distro though.

Just loaded up a minimal installation - great job! I notice that you have not used busybox, is there a reason? With 347 commands in a 1MB file, should be good savings in size. I will start to replace commands with busybox and check savings (first cab off the rank is to add 'vi'). FYI: For anyone int...

I had the same (similar?) problem with one of my B+ boards - the one with the Gertduino board installed. I have stayed out of this thread so as not to confuse matters. My problem I believe I caused by recently running raspi-config and deleting en_US and en_GB from the locales while keeping my en_AU ...

I have the same problem with one of my B+ boards. It currently has the gertduino board installed and whatever recommended software. Will find some time to try and track this down, unless someone else hasn't already. The kicker line is with dpkg: unable to make backup link of `./usr/share/i18n/locale...

I have set up a system, mainly using Dave Welch's code - modified. Currently I'm using it "pi2pi" where I use my mini-terminal program plus his downloader program to download, test and reboot WITHOUT pulling the SD card or powering on/off the bare metal pi. Some examples including gpio, sp...

7/22 is an approximation of ip not pi

Using that bootcode.bin ::
Both the Model A 256MB & the Model B 512 MB appear to behave as normal.
The Model B+ seems to have fixed the "proximity switch reboot" feature
including, as noted previously, return of the ten pulse shutdown sequence.

Try 'comment out' the driver line with a # in front.
The system should pick up the correct driver.
Works for me.
