PGA output is not available on the pin

[SaKu_291986]

    
•  I created a new project using CY8C29466.
    
• I placed a PGA on ACB00
    
• PGA input is set to AnalogColumn_InputMUX_0
    
• InputMUX is connected to P0[1]
    
• PGA Analog Bus is connected
    
• PGA Gain is 1
    
• PGA Reference is AGND
    
• Buf 0 is connected to Port0[3]
    
• P0[1] is supplied input voltage with a pot 0 - 5V
    
• P0[3] does not follow P0[1] but stays near 0V
   

   

Anyone have an idea how to solve this problem?

Your settings look something like this -

                   

And you issued a PGA_1_Start( PGA_1_HIGHPOWER ).

       

Lastly code looks something like -

       

#include <m8c.h>        // part specific constants and macros
#include "PSoCAPI.h"    // PSoC API definitions for all User Modules


void main(void)
{
    // M8C_EnableGInt ; // Uncomment this line to enable Global Interrupts
    // Insert your main routine code here.
   
    PGA_1_Start( PGA_1_HIGHPOWER );
    while ( 1 ) {
   
    }
}

Hello SuperFlanker,

       

Please Ensure the following steps:

   

    
1. In global resources window, check "Analog Power" parameter: It can be any setting but "All Off', for your PGA or any analog resource to recieve power.
    
2. You have to call PGA_Start(POWER) API for enabling power to your PGA.
    
3. Ensure the Drive mode of P0[1] and P0[3] is set to 'Hi-Z analog'
   

   

It would be better if you can post a screenshot of settings or upload your project for assissting more aptly.
