Means, the probability that a false trigger occurs due to charge injection via stray capacitance is greater by a factor of 100. Dear kai, hello, greater by a factor of 100 than what? than not occuring? I suppose it also deponds on the actual value of stray capacitace, dosn't it? Copper traces connecting the keys of your keyboard to micro are rather long and present ideal antennas, best suited for picking up hum and noise. I agree. double checking of the pin value is not a hard job, but I wanted to know why it is absolutely necessary. this reasoning seems acceptable to me. thank you very much best regards |
