Meetings for This Week:
Programming - Tuesday 14th Mar - 5:30 pm - 8:00 pm
Come and show your projects, and see some others. We have a computer with a projector, so bring along picture files of your project and we'll project them on the wall. We have a broadband internet connection, so discussion can be wide ranging.
The next meeting will be on Tuesday March 14 at 6pm. We'll see some new microprocessor applications and programming examples.
At the February meeting Steve talked about the STM32 ARM Cortex, and developing code online:
Microchip's free C compiler is limited in many ways (bloated executable code, perverted time delays, limited size code, printf won't print floats). So he looked around for other devices that had better free-of-charge software support.
The STM32 processor range is very popular, with good specifications and prices. He bought an STM32 Nucleo-F411RE (ARM Cortex M4) development board for $20 delivered from RS Components. 100MHz, 512K flash, lots of IO, AtoD, timers etc.
The board includes the ST-Link programmer and debugger which can be snapped off and used separately.
ARM operate an online IDE (Integrated Development Environment) and C/C++ compiler that is free to use. This avoids many of the hassles related to installing and configuring software tools like IDEs and compilers, since it is all online and accessed via your browser.
The programmer appears as a USB device on your PC, and when you save a binary to it the microcontroller gets programmed.
Some downsides are:
No internet connection means you can't program or compile.
Your code is in the cloud. It is only public if you make it so, but it is still less secure than programming on your own stand-alone PC.
Sometimes the ARM compiler is very busy, and compiling a short program takes 30 seconds or more, but usually compiling is less than 5 seconds.
Web Design - Saturday 18th Mar - 1:30 pm - 4:00 pm
This month we will see if we can get the kids interested in Web Design.
The website envato tuts has a free tutorial Called "Web Design for Kids". The tutorial, written by Joni Trythall builds a simple one-page website.
It has eleven tutorials covering all the basics. The first one starting with sketching a site; others such as: what editors are available, how to organise your files and using a browser to check your work.
The tutorials go on to cover topics including CSS, HTML, design, layout, images and typography.
Hope to see you all.
Meetings next Week:
Tuesday Group - Tuesday 21st Mar - 9:30 am - 12 noon
Family History - Tuesday 21st Mar - 1:00 pm - 3:00 pm
