Can i Study at Matrix Multimedia?

[greentech]

If i want to learn embedded programming is it possible that i can come to matrixmultimedia and learn it from the experts. Do you offer courses also?
Coding is wha ti am not familiar with, probably that is the reason i am finding it very hard to program a simple irda.....

If there are some courses, what is the tuition fees and course length?

Urgent Response Needed?

hello steve i am unable to find the contact numbers for studying at matrix.

Please guide me for the procedure of international students.
how long will the course last.

Best regards

[Steve]

These are day-long training courses, so I don't think it would be worth coming from abroad to attend.

Hello,

Our dealers sometimes arrange training in other countries. Maybe it is worth contacting a dealer in your area and seeing if they can offer you any courses or training.

Dear All,

I am facing a problem with boostc compiler. it was working fine few days back, but today when i compile to HEX it pops out a window saying "BOOST~C.EXE stopped working. I have checked compiler options, and restored them to defaults, but invain"

can u give me a clue whats wrong with it?

Have you tried uninstalling and reinstalling Flowcode ?

[greentech]

yes but it didnt help.

Have you got a firewall like comodo which could halt processes that have not been assigned to trusted applications.
If you are using Comodo, try running Flowcode, with comodo in Training mode for both Firewall and Defense security levels.
Or
It could be caused by boostC being halted by an antivirus.

Of course it could be none of the above, but anything is worth a try?

Hello,

Your best bet is to find a reference project online. If its easy and its possible then you should find a project without much searching that will give some example components maybe with a schematic and some source code.

When i'm searching for things in Google I normally use the following types of keywords.

Project
Source Code
Reference
Schematic
PIC
AVR

eg.

laser distance project schematic PIC

seems to bring up some fairly relevant pages.

Thanks benj ill try that

Hello there,

I have defined three float vars

time=1,000,000
c= 299.792458
d=0

i have then calculated this

d= C*Time and it gives me the wrong answer (5084480.087680)......

can u tell me where i am wrong. The answer should be 299792458.....

Hi greentech
Just put a quick program together
Try the attached flowchart
It works here in simulation, though not tried it on hardware

this is what it displays on real hardware. {30816.//////}
em confused.

em confused.

The calculation is correct, I confirmed that with ICD mode on.
To me it looks like a bug with conversion of float to string.
I believe what John posted is correct.
Unless I'm missing something obvious?

[greentech]

what to do now. can i fix this error somehow? it works in the simulation alright, but on real hardware its confusing me.

best regards.

[greentech]

float d = 299792458
divided by 1000000000000

it gives me the answer 0.000300

whereas it should be 0.000299792458

whats going wrong?

Hello,

I'm guessing your doing these large calculations on an 8-bit device. In which case the functions to handle these numbers may introduce rounding or other simplification which is probably what you are seeing. Maybe a 16-bit PIC or an ARM would be better suited to these large calculations. Otherwise is there a way to change the maths so that you are not dealing with numbers that are so large or small.
