PIR Input Not Turning On Lamp; Manual Control Works With Slider.

[Testroadtech]

Hi,
I have a problem with my Xiao ESP32S3 Sense Camera board not turning on the Lamp pin when the PIR pin goes High. I have the peripherals set to true in the appGlobals.h file, and am using GPIO 2 for the PIR and 3 for the lamp (board pins D1 and D2). [Edit: Checking the schematic, I saw GPIO3 (D2) was also used for the SD card, so I tried GPIO1 (D0), and all the rest stays the same] When I put 3.3v on GPIO2, I can see the user interface "Start Recording" button turn green, and the video records, but the Lamp pin does not turn on. If I change the "How lamp activated" option under peripherals to "Manual", the LED turns on to whatever brightness setting it is set to under Camera control. I can dim or brighten the LED with the slider. I save all setting changes and reboot the ESP, but am not able to consistently get the LED to turn on. I am using a discrete Cree 5mm white LED ( https://downloads.cree-led.com/files/ds/h/HB-C503B-WAN.pdf ), with 3.2 forward voltage and a 10 ohm current limiting resistor to limit current to 20 mA. I have the same symptoms on a second otherwise working board. I also tried adding a 39 ohm resistor in series on one in case 20 mA was too close to max current. No difference in symptoms.
Has anyone dealt with similar issues? I would appreciate the input.

The same thing occurs with a Freenove ESP32S3 Cam board, only the LED is the onboard WS2812 on pin 48, and the PIR pin used is GPIO21. The application knows the Lamp is a WS2812 from the board pin definitions, and the slider varied the brightness. Has anyone been able to get the Lamp to light from the PIR pin?
