Dear all
I am looking for simple algorithm input.i cant post whole code. i pasted some part of it
i have used pic16F886 ic
i am using PISO to get input from 74hc165D ic. here i am trying to read data from DIP switch. Fault_Array[0] uses to read 8 position DIP switches
Now i am trying to read above input and identifying which is latest input. IN this code assume i have 4 input F1,F2,F3,F4 where F4 is latest f3 is 3rd and f1 is first. as per below code F4 will be flashing and remaining F1,F2,F3,will be steady. i m expecting First input F1 flash first later should be steady
similarly if order F2 is first, F3,f1,F4 i/p F2 is first i/p it should be flashing and remaining should be steady.
here i am checking which input is latest input.
using this i am trying to flash output

i am using PISO to get input from 74hc165D ic. here i am trying to read data from DIP switch. Fault_Array[0] uses to read 8 position DIP switches
Code:
void PISO_INPUT(void) {
unsigned char i;
unsigned char j, k;
unsigned char value;
byteValue = 0; // accumulates image of 8 switches
bitValue = 0;
PISO_PL_EN = 0; // latch data
PISO_PL_EN = 1; //ADD
for (i = 0; i < Chk_Fault_Counter; i++) { //TBC // 8 bits
bitValue = PISO_FAULT;
byteValue |= (bitValue << ((Chk_Fault_Counter - 1) - i));
PISO_CLK = 1;
PISO_CLK = 0;
}
FAULT_PISO = byteValue;
Fault_Array[0] = (unsigned char)(FAULT_PISO & 0xff);
}similarly if order F2 is first, F3,f1,F4 i/p F2 is first i/p it should be flashing and remaining should be steady.
here i am checking which input is latest input.
