Hello all ,

i have a custom PCB with PSOC4 on it ,

i have 1 input pin controlled by a switch (switchPIN),

i have 2 outputs pins (resetPin , onoff_Pin),

i need to implement the following logic :

starting state is switchPIN=1 in that case turn on onoff_Pin-->1,

if someone turn the switch off switchPIN=0 and 6 sec is passed then turn off onoff_Pin-->0,

but if someone turn the switch off switchPIN=0

and BEFORE 6 sec is passed he turns on the switch switchPIN=1

then send reset pulse (resetPin =1 wait 100ms then resetPin =0).

this simple logic is driving me crazy, i have tried using 2 timers with isr on

the switchPIN (one is 6 sec timer , and one is a fast timer),

i just can figured out a way to do it .

can someone direct me to a simple solution to this problem ????

I have attached a flow chart of what i want to achive .

Thanks in advanced.

Hi,

I tried by myself with CY8CKIT-044.

It seems working, although not quite tested

Hope this can be a little help for you.
