#147963 - start button? Responding to: ???'s previous message |
How start button is implemented? As normal-open between
VCC and P1.4 ? This comes from sourcecode, but is unusual . You must have resistor (2k..5k) between P1.4 and GND. Usual for 8051 is switch as TLS or BLS - normal open between pin and ground. If start button is connected as TLS - use "JNB SB,up". regards |
