Air Quality 2 click compiling problems

[Mysse]

Hello,

I'm trying to get example of Air Quality 2 click to get compiled, but i receive errors. Example is taken from https://libstock.mikroe.com/projects/do ... ft90x.mpkg help file example air_quality_2_FT90x.c

I have mikroC PRO 2.2.1+visual TFT as software and HMI 5" FT900 Rev 1, hmi-bb and mikroprog for FT90X as hardware.

Compile errors:

Code: Select all

I tried this as workaround for errors:

Code: Select all

float co2_array[12] = { 0 };
    int co2_array_ind = 0;

    //co2_array[*co2_array_ind++] = sample;
    //if(co2_array_ind == SAMPLES) co2_array_ind = 0;

    for(i = 0; i < SAMPLES; i++ )
    {
        co2_array[i] = sample;
    }

But then i get this:

After commenting this line and doing my workaround:

Code: Select all

// iaq_status = air_quality_2_click_info(&info);

i get prog compiled but its not getting any readings

Terminal:

Code: Select all

Status:		OK

CO2:		0	ppm

TVOC:		0	ppb

Resistance:	0	ohm

Any help is appreciated.

Hi,

When you open example go to Project -> Edit Search Paths, then in section Header files and Source files
click on Add header path and Add search path icon and then in both cases choose Uses in Click_Air_quality_2, and at the end click on Apply.
I think this should solve the problem.

Best Regards,

I have added search paths for it before trying those desperate measures

But i have purchased clicker 2 PIC32MX to make sensor readings to HMI via serial, since PIC32 seems to have better support on click boards at libstock. Hope it all will sort out better and easier with PIC32.
