I encountered a strange phenomenon when developing a proximitysensor by using posc5:
If I set the tuning method to Auto(smart sense), the proximitysensor will always be active, which means the led will be continuouslly turned on by LED1_Write(0u);
But if I set the tuning method to Manual, the proximitysensor will never be active even though I set the finger threthhold low to 40.
The program goes as below:
The proximity sensor is a 2mm wide copper strip circle on PCB, with a size about 100mm*150mm .
Thank a lot for your regarding.
