Hi,
The strip force is like normal resistor. It connect with LED then when press the strip the LED will light up. My strip force range is 10g-1kg. Now the problem is when i step on the strip, the LED still will light up. Below is my program:
ORG 0000H
MOV R1, #00000000B
TEST: ORL P3, #0FFH
JNB P3.0, CASE1
AJMP TEST
CASE1: MOV A, R1
MOV P1, A
XRL A, #00001111B
MOV P1, A
AJMP TEST
END
