what is the formula that will help me to get the values of the frequencies depending to the values of R and C in the figure below
i need the correct formula pleazzz
I know that from the constant above the value of after the EQU must be address from the memory not value …..when I need to insert value to a variable must use MOV instruction ….
And also the option_CFG if that mean the option register so the address of this register is in HEX (81h) … fi I need...
Thank you very much for this effort .....
I will read more about TMR0 interrupt, and will wait until your return to complete this work
thanks for your help .... you are good man
thanks very much for these informations , but i have a little information about that ... i mean if you can convert these information to code i can trace and simulate it I would be grateful . and i will study this information too
Note: i have two sensors : one to move the second motor forward...
Thank you very much for your help ... I want your help if allowed Could you help me in the work of code for this project to be benefited from your expertise in this field >>>> my problem now is using two sensors and two motors how i can solve this problem and what is type of interrupt is good to...
this my code... and i'm not sure is it ok or not .... i think there are many mistakes and i need your help to imroving it and thanks a lot for reply
List p=pic16f84a
include <p16f84A.inc>
__config _XT_OSC & _WDT_OFF & _PWRTE_ON & _CP_OFF
; variables in PIC RAM...
i wanna your help pleaz
i want to control two srepper motors using pic16f84a
i need the first stepper motor to move one step every one minute without stoping until the PIC senses from external sensors in this moment i neen the first to stop and the other stepper to move one step only and...
Re: can any1 help me????
hi man
i got this problm too .....
try to fix or make sure of your LPT or if you are using COM cable and its wires >>
and good luck
hello every body
i have some questions ......
what is meant by Pull up in the Option reg.
and if there are programs to design microcontroller circuits pleaz dont forgot me
and thanks
look to the code below .... the delay code of 4 second is in the red color.... and the main code in the black .... when insert the delay code to the main code and convert it to the Hex file ... there is no error and the process is success ...... ,and when loaded to the pic the loading is success...
thankx very much for help
but If you can explain this part pleaz >> i need to know when ($+2) is come what the next instruction will be executed in this part (Delay_0 or decfsz d2, f )
Delay_0
decfsz d1, f
goto $+2
decfsz d2, f
goto $+2
decfsz d3, f
goto $+2...
hiiii everybody
this is delay call function for 5 minutes but when i used on my pic16f84a and applyed my circuit it didnot operate >>>
i need konw what ia meaning by ( cblock ) in this code
cblock
d1
d2
d3
d4
endc
and what is meanining by ($+2)
; Delay = 300 seconds
; Clock frequency...
