GPS expansion module code example

Monie Jacobsen · Post by **Monie Jacobsen** » Fri Feb 24, 2017 10:51 am

I purchased MAC - GPS expansion module type: MI8582
But want connection examples.
Want to use the GPS device connected MIAC (Arduino) type: MI5466
Or connect to the ECIO40P.
Can not fine document or connect or code examples for output.

Is there anyone - who will want to help with coding as described below.

For output as:
Sec, minute and hour.
day, month and year.
Latitude and Longitude

Will be very pleased code eksemple

Hi Monie,

Attached is a MIAC System GPS example to get you started.
It also revealed a little bug, so please also update the MIAC_CAL_SYSTEM.c in your Flowcode \CAL\MIAC directory.

Regards,
Leigh

Hi LeighM
Many, many thanks.
Will immediately test codes;-)

Good weekend

Hi LeighM
The wires from CAN L and H -where they must be connected to the MIAC (Arduino-Compatible) ??

Post by **LeighM** » Fri Feb 24, 2017 4:09 pm

On the MIAC, top left, T, CH and CL.
Module CAN L goes to MIAC CL
Module CAN H goes to MIAC CH
To activate the internal MIAC CAN terminating resistor, also make a wire link between T and CH on the MIAC Ardunio

Hi LeighM
Thank you.

Hi LeighM
MIAC GPS expansion not working in practice?????

Without GPS Ice Data Valid function:
MIAC display shown below:
----------------------
10:13:30 27: 02: 2017
Latitude: 0.000000
Longitude: 0.000000
Satellites 247
-----------------------

But why is Latitude and Longitude does not work?

Do not come out of "Data not yet valid" and does not start up GPS.

Have 120ohm resistor is connect to the CAN L and CAN H terminals on the MIAC GPS expansion module.

Hi Monie,

On hardware, is the LED on the GPS expansion module flashing?
If so, then that means that the CAN connection is OK.

You listed the time as being shown, so that would also indicate that the CAN connection is OK.
Your flowchart is very good, but I noticed you had a missing return of the state variable ...

I've fixed that in the attached and also moved the time display.

As for the location information it could be that the GPS module has not yet locked onto enough satellites to provide a reliable result.
Is the module in a location where it has clear "sight" of the sky?

Regards,
Leigh

Hi Leigh
Now it seems the device correctly.
Thank you for your patience;-)

GO'Working

Hi Leigh

Can I convert file-format from the flowCode v7 MIAC (Arduino-Compatible) Systemfor Arduino
If yes, how is this done below.
Do you want to be helpful with a small eksemple?
Do like to be with component "C code"
Or another suggestion from you;-)
Please see below!

Convert at Flowcode to float latitude Arduino.
Convert at Flowcode to float longitude Arduino.

Convert at Flowcode to float month Arduino.
Convert at Flowcode to float day Arduino.
Convert at Flowcode to float hour Arduino.
Convert at Flowcode to float minute Arduino.

Hi Monie,

We do not yet have any support for the MIAC Expansion modules (MIAC System) with Arduino code.
I would be possible to re-use the MIAC_CAL_SYSTEM.c code and the C code generated by the Flowcode components to create an Arduino library, but not easy.

Using Flowcode gives the simplest way of creating MIAC System (CAN Expansion modules) applications.

Hi Leigh
I have been able to use the following C Code in Flowcode v 5 to v6
Why can not I upload the file (Flow Code v7) including?

Have a suggestion for another C Code?
Or another way to solve the problem?

Hi Monie,

The variable names in C are case sensitive and Flowcode uses upper case.
The Flowcode variable can be dragged into the C code ...

Your month_day[] array probably needs re-defining in the Build->Project Options->Supplementary Code

Hi Leigh
Thanks for your reply for C code;-)

Have work all day in below
Want degree as below
180.5 °

: degree.JPG (28.69 KiB) Viewed 16614 times

Can easily make it in Flowcode but not in MIAC
Do you have a suggestion?

Post by **LeighM** » Tue Feb 28, 2017 4:48 pm

Hi Monie,
I will try and add that in the next day or two.
Regards,
Leigh

Hi Leigh,
That is great.
I welcome very much ..

Post by **LeighM** » Thu Mar 02, 2017 10:54 am

Hi Monie,

I've added the degree symbol to the dsPIC and Arduino compatible MIAC Flowcode components.
Please update with the attached files...

MIAC (Arduino-Compatible).fcdx and MIAC (Arduino-Compatible) System.fcdx to go into your Flowcode7 installation \FCD\AVR directory
MIAC (dsPIC).fcdx and MIAC (dsPIC) System.fcdx to go into your Flowcode7 installation \FCD\PIC16 directory
MIAC_CAL_API.c to go into your Flowcode7 installation \CAL\MIAC directory
miac_dspic.fcpx and miac_arduino.fcpx to go into your Flowcode7 installation \components directory

Regards,
Leigh

Monie Jacobsen · Post by **Monie Jacobsen** » Thu Mar 02, 2017 11:48 am

Hi Leigh,
Many, many thanks for your many devices ..
I immediately try out the units and the degree symbol showing now in Miac display, with code: PrintASCII (223)

Enduring many thanks for your work;-)
Continued go working ..
