Meeting Proceedings for 9th November 2018

End of year Barbeque was discussed and it was agreed that we have a combined BBQ at the Croquet Club 259 Portrush road Norwood.  Start time 6:30 pm
Rick M presented Part 1-An introduction to the evolution and flavours of Linux.
We are looking forward to further presentations on Linux.
A Steering Committee was formed and David and Kevin will investigate the purchase of a Mic and Video Camera and will report back on their findings.
Cliff Shirra gave a short presentation of the ATMega328p USART in SPI mode.


2018-10-12 October Meeting Agenda

At recent meetings, several members suggested that we revisit the ATMega328 microcontroller as there are possible issues with software and communications. Due to Windows updates there are changes when loading software into Windows 10. We will be revisiting the installation.

  • Please bring your laptop, little 328 Development board, USBAsp and we will play.
  • You may have alternative programmers and development boards which will be of interest to everyone so please bring them along.
  • Cliff will revisit “fuses” at a basic level.
  • If you want, bring along any projects, even if they are not completed.
  • Future projects and purchases

2018-10-12 October Meeting Summary

Friday’s meeting ended up being very interesting. Peter G went through the requirements for setting up a computer running Windows 10© to program an Atmega328p development board via an USBASP. It was seen to be quite straightforward using available driver and driver installation software. Peter also went on to describe the use of a FTDI (USB to serial TTL) so we could use Arduino IDE serial monitor. In effect the USBASP was used to program the Atmega328p via ISP and the FTDI was connected to the Rx and Tx pins of the micro so our computers could monitor various occurrences.

Some people brought in other programmers for other types of micro-controllers.

Chris B demonstrated his ability to test individual memory locations on memory chips using his own firmware on a STM micro

Cliff S went though some very rudimentary fuse settings. It is seen attached data sheets to the various electronic devices are a valuable tool to be referenced when necessary.

Kevin Z suggested that now most have constructed their Component/Transistor tester we should investigate recompiling and extending its features to test Zener diodes.

Adam W did a brief follow up on his ongoing “popcorn” project, modbus and RS485

Preamble: The feedback and input contributed by all SAMG members was very positive which led to some further clarification with respect to our diverse needs and wants as a club and personally.

Regarding our website Website administrator Graeme Wilson has been actively reviewing and changing our website to make it more relevant to the public and members.

Discussion on SAMG website included suggestion to move to alternative product called BootStrap.

It was agreed however, that a simplification of the site’s menu structure (site-mapping) would be beneficial and content to be focused on club activity only.

WordPress would remain as it is the easiest to maintain at this time as it is used by 75% of similar websites.

It is “work in progress” and the site will change and progress continually to make it relevant and pleasing to navigate and use.

Past, present and future reflections with club topics and projects

It was noted most members were satisfied in most areas.

It was mentioned that we could:
Take a closer look at utilising STM32 (Bluepill)
Since many of us have a PINE64, possibly revisiting Linux (Rick M has generously volunteered to further our education in this area and will start his presentations on the 9th of November this year)

Personal or Group Projects

Group or Individual suggestions:

  • It was mentioned that we could look at monitoring, retrieving and re-purposing Weather Balloon radiosondes (either re-flashing or trying to decode output from these devices)
  • Take a closer look at the STM32
  • Look more closely into the micro architecture
  • Delve into the possibility of retro-computing
  • Investigate the use of Raspberry PI
  • Going back to basics
  • Possibly reviewing our use and implementation of the ATmega328. Making sure that we all have a working combination of computer, USBASP and 328 development board. Along with an IDE.
  • Lapel microphone, webcam

A brief discussion on the benefits of sharing the meeting using streaming technologies so absent or distant members can view tutorials, lectures and participate in meetings. Cost will have to be reviewed and further discussed amongst the committee members before any progress will continue.

Start Time: Changing the meeting time to 7.30 was tabled and voted amongst the members. The vote was in agreeance to change the time to 7.30. It was stressed any member can arrive before this time if they want to. The meeting room doors should be open. These members must wait if the room is already occupied by another group.

General Input: It was suggested our group may be able to hold “Swap, Barter or Buy” nights.

Presentations: Cliff Shirra did a short presentation on PCB (printed circuit board) manufacture. This will be available on SAMG website for general viewing.

Ad hock Presentation: Adam Web did a very interesting presentation on a project he has/is doing. It covered a hybrid of Arduino and commercially available product that included the use of a touch screen HMI (human machine interface) and MODBUS. Adam also discussed RS485 and RS422 standards.

Meeting Closed: 10:55 pm


2018-08-10 August Meeting Agenda

SAMG Special General Meeting to be held at 8 pm 10th August 2018 at WEA Cottage Angus Street

After the Special General Meeting, Peter Gheude will present an introduction to high precision AC Servo Motors and their associated encoders.

We have some examples of the high torque and precision devices which are used in CNC machines and robotics.

Our Special Guest for this evening is Peter Rosenthal who will bring along some items for demonstration.

If anyone  has related items or examples please bring them along as well.

Before the SGM, Peter Gheude will be collecting membership fees of $10, for the year February 2019 – 20.

From Peter Gheude:
I am calling a special general meeting for the 10th of August to elect an interim Chairman until our next AGM when all positions will become vacant.
We have been privileged to have Eric Clarke as our Chairman for the last few years. Unfortunately he has been compelled to resign as Chairman of the South Australian Microprocessor Group.
His outstanding contribution must be applauded. He has performed the Chairman’s role, reworked our website, and shared his electronics and microprocessor expertise with everyone.
We have all been personally enriched by association with him, and our group has greatly benefited as well.

As Secretary, I feel fortunate to have had the opportunity to work with him over this period.

I would like to sincerely thank Eric for generously sharing his time with us.

The role of the SAMG Chairman is to;

  1. chair or preside over the committee,  general or special meetings
  2. produce the agendas assisted by the secretary and membership
  3. head the committee in making decisions for the benefit of the group
  4. disciplinary matters and settling disputes amongst membership
  5. lead group in terms of strategic short and longer term planning
  6. manage SAMG affairs by always seeking collaboration
  7. consult and delegate by consensus, special roles to the committee and membership
