proximity sensors

[Anonymous]

hello,

   

 I wanted to know if it is possible to use PSoC5LP the  proximity sensing with the CY8CKIT-059.

   

Thanks.

Welcome in the forum, Florian!

   

Yes, you may use CapSense and proximity sensors with the -059 kit. The needed capacitor CMOD is already on the board, so you just need a wire connected to the pin of your choice.

Thank you Bob,

   

I tried to do the same thing as in this video: https://www.youtube.com/watch?v=BMslzJHodyg&ab_channel=FutureElectronics. But I did not find  the location of the bootloader. So please do you have an answer for his location? Or a solution for use the proximity sensors .
Thanks

Your -059 kit has got a kitprog which you use as programmer and debugger. You do not need a bootloader or bootloadable component.

So if i do the exact same thing as in this video but without the part with the bootloader it should work?

   

Thanks.

Yes, you can! Care fot the LED-pin which is Port2 pin 1 for the -059 kit <8different from your -49 example)

Thank you,

   

So I wrote this :

   

#include <project.h>

   

int main()
{
    CyGlobalIntEnable;
    CapSense_1_Start();
    CapSense_1_InitializeAllBaselines();
   
    CapSense_1_EnableWidget(CapSense_1_PROXIMITYSENSOR0__PROX);
    for(;;) 
    {
        CapSense_1_ScanEnabledWidgets();
        if(! CapSense_1_IsBusy() )
        {
        LED_Write( CapSense_1_CheckIsWidgetActive( CapSense_1_PROXIMITYSENSOR0__PROX ) );
        }
        CapSense_1_UpdateEnabledBaselines();
    }
}

   

but when i put the wire for the proximity sensors the LED is on and she is on all the time excpet when there is no wire. So what is the problem?

[Bob_Marlowe]

You repeat ScanEnabledWidgets() over and over and do not wait until it is done. Do not use an "if", instead wait until not busy.

   

I frequently use

   

#define Wait(x)     //  Just for the readability

   

...

   

while(CapSense_1_IsBusy() ) Wait();

   

...

It works, thank you!! 

[Bob_Marlowe]

Great! But seemingly took you a long time to evaluate. Holydays???
