    Measure battery level

    dudi_2364576

      I am trying to implement battery measurment by connecting vref to SAR_ADC internally but get un expected results.

         

      I must connect externally between VREF pin to P1[7].

         

      I have 1uF on VREF pin and 1uF on P1[7], i used the firmware code inorder to connect VREF and delay for a few miliseconds, then reconnect VDD. The results i get are wrong until i connect externally between VREF and P1[7].

         

      I am using PSOC 4 BLE?
