Please..Help me..Clock signal from the outside with the TMR0 Clock Making? (T0CKI)

[vasili35]

Friends .. 555 square circuit with the signal received by the signal clk T0CKİ end of an hour trying to make a simple halves .. But it does not work ...Did heI shared my code and circuit file. help, not Constantinople...
External clock signal for clock signal generating you have another suggestion?
(A brother-wave producing circuit 555 seconds)

Device = 16F876

Config WDT_OFF


ALL_DIGITAL   =TRUE
Declare LCD_TYPE 0
Declare LCD_DTPIN PORTC.4   
Declare LCD_ENPIN PORTC.3   
Declare LCD_RSPIN PORTC.2   
Declare LCD_INTERFACE 4     
Declare LCD_LINES 2

INTCON     = %11100100
OPTION_REG = %00100000
TMR0=0

Dim say    As Byte
say = 0

ON_HARDWARE_INTERRUPT GoTo Cut

GoTo Main

Cut:

say=say+1

INTCON.2=0

Your post mentions 555 twice...

And the left-hand part of your circuit has components arranged to resemble a 555 IC oscillator circuit.

However your pins are not numbered the same as the 555 chip.

It won't give you a clock signal.

So using the external clock signal, where do I get the signal for the TMR0? What advice?
