Re: Source control poll

Now I'm curious whether very many use source control at all or whether their day jobs simply don't cross that path. I probably should use source control, but hardware has my main business for decades using C to get things working. Application Lifetime Management is something that kept biting me whe...

Re: Opengl performance on RPI Z

Uhm, this is interesting. So there's no separate memory for graphic card? Like, i thought that once the texture is uploaded, it would stay in the "realm" of the graphics hardware and not consume anymore bandwidth. For OpenGLES/VG stuff, config.txt sets the GPU memory. Eric's Mesa 3D drive...

Re: Opengl performance on RPI Z

OpenGLES can be fast, even on a Zero, check Tim's videos. https://www.raspberrypi.org/forums/viewtopic.php?p=1327637 He has not posted any code yet so it is still magic to me :lol: But I have yet to get my head around it for Ultibo. Cubes I get ;) https://github.com/ultibohub/Examples/tree/master/Vi...

Re: microbit as ultibo peripheral

Garry, try these guys, I seem to be getting more and more from them because they have stock at reasonable prices for OZ.

Better Software Faster

I'm a hardware guy with no professional software training (er, 1 semester Z80 coding?), but I have been reading about software for decades. C++ Journal, Dr Dobs, Byte, Circuit Cellar etc Today I got a a newsletter from Jack Ganssle, there was a mention of his talk "Better Software Faster"....

Re: vnc - virtual network computer - ultibo

The goal is: the Rpi/Ultibo can display a picture from Windows PC connected to it

Would RDP be easier than VNC? At least from the server Windows PC side.

I have found it simpler to get a RDP client on a Linux box to talk to the native RDP on the Windows server.

Re: microbit as ultibo peripheral

L298 is common simple Dual DCC 2amp power driver, LMD18200 is 5Amp driver. A google will find you the circuits. Most of my old stuff is 2mm/N scale narrow gauge but my eyes are to old now, time to go to 16mm/ft on 32/45mm track :D With that scale, Zero plus cameras are easy. Hmm perimeter security g...

Re: Misc questions, graphics and games

For testing graphics coding I use a Zero plugged into a USB port on a Linux PC. https://github.com/raspberrypi/usbboot Scripting languages have been discussed, a search will find them. http://luapascal.luaforge.net/ I think Pascalscript is the closest to working? Initprog or initunit is unit that ge...

Re: microbit as ultibo peripheral

Duh! must be getting old, that's how how you update the Microbit's code, just drop the file onto the MSD. Pi B+'s can handle 4 Microbits via USB :D Thanks Garry. Hmm interesting to try Zero's, may need to grab some USB connectors and make some tiny cables. Microbit's can do SPI, USB LCD drivers? Wis...
