Re: microbit as ultibo peripheral

Well done. Bit too fast, can still lose a count on fast presses. Working fine on a 3B :D My 3B+ is busy rebuilding itself on a SSD after the expensive uSDcard nearly cooked itself :( Do not Compile C compilers on uSD cards on PI's it takes hours and days of doing that wears out uSD cards. Failure mo...

Re: microbit as ultibo peripheral

Yep I am finding Bluetooth a pain to develop, now have about 6 different architectures from 4.1,4.2 and 5.0. Lost track of development tools i tried, 7 to 12? MU is just an editor, was supposed to make it easy, but I found even installing it has issues ;) Using BLE as sensors for IoT I am trying fir...

Re: Pakt book today: Delphi High Performance

One thing I really like about Ultibo is the multicore support.
But I have yet to use it apart from the example code.
A book like this could be just the thing to inspire more parallel coding.

It seem silly to me to have these 4 core Pi boards and not know how to use them to the max :D

RISC-V

While trying to manually install FPC 3.3.1 and Lazarus 2.1 on my Gentoo64 Pi I noticed riscv, riscv32, riscv64 compiler src code. Days before I had installed all the RISC-V tools on Gentoo64, 13 hour build in gcc and folder size of 12.7GB. No idea how to make fpc cross compilers on Aarch64 yet but I...

Re: WebGL

I ran into an article about baremetal containers. Turns out baremetal is referring to applications running on the baremetal and not in a container with the OS like most VM/Docker stuff does. One thing I use Pi's for is data visualization of logged data. I don't have OpenGLES 3D visualization yet but...

Re: Tricks and hints

GLSL/ESSL, thanks, saves me wasting too much time learning the wrong bits of GLSL. I need a list of OpenGL similar commands that are in OpenGLES and now GLSL to ESSL. WebGL uses OpenGLES and ESSL This looks useful info. http://www.pp4s.co.uk/main/tu-sms-graphics-3d.html Wow wonder if that demo can b...

Re: Building from source in OSX

I normally use USB boot mode on Zero's.
Saves SD card wear and is a bit quicker.

Not sure if the Zero identifies as a 500ma USB device?
It would need to if a LCD with backlight is also running from the USB port.
Now you got me interested I will have to try this ;)

Re: Building from source in OSX

Hard to keep up fpc, 3.3.1-r20 is also working in Aarch64.
Not sure if 3.2/3.3 will break Ultibo anyway, so no hurry, still trying to get Laz 2.0? going.

Re: Building from source in OSX

The thing that stands out is that it is looking for ppcarm but the cross compiler should normally be called ppcrossarm instead. My Gentoo64 3.2.0-Beta fpc is called ppca64, that will only compile for Aarch64. So for Ultibo I will need a ppcarm version that runs on Aarch64? Would that be called cros...

Re: fpga for ultitb

Turns out FPGA's can be low power too, must have been a long time since I checked. This one looks interesting, apparently 5.3K LUTs is enough for a RISC-V micro too. http://www.latticesemi.com/en/Products/DevelopmentBoardsAndKits/HimaxHM01B0 It can do vision recog :o This FPGA is the UP5K used on th...
