Unable to access Opamp output in PSoC® -062-BLE Pioneer Kit - KBA225513

Question: Why Opamp OA0 output is not available in the pin 9[3] while OA1 output is working fine with the same Opamp settings?


Answer: In CY8CKIT-062-BLE pioneer kit, by default Pin 9[3] of the device (also the output of OA0) is connected to TRACEDATA_0 and not to I/O header J2. You will need to short R131 if you want the pin to be connected to I/O header. Please refer the Figure 1 to see the position of the resistor.
