hi dear friend...
i am going to use ARM Cortex A8(AM3359) processor for one project...i read that,IAR and CCS compiler will support for this processor..i need help for ,i dont know how to write code for this controller using C... also i dont known what kind of register v have to set or...
i have to use DAC ya...herewith i enclosed my proteus design and program. still i have doubt in,how to generate sine wave in different frequencies ... like 100Hz,,500Hz,100KHz,500KKz

i've to use PIC and DAC ....
Hi friends ...
i need to generate sine wave in 100Hz . i don't known how to generate and how to interface with PIC.
I am using,
*PIC16f877A controller
*16Hz crystal
* MPLab Compiler .
*0808 DAC
so try to give sample code and hardware circuit for sine wave generation. i am expecting...
hi friend .... in row side i am connecting ULN2981 ,so i think it enough that brightness ,but still also i feeling difficult, to control data flow ...also what is refresh rate ? how to calculate this .... i am expecting valuable reply
ok fine dear friend ... herewith i add rar file. it contain full code , Proteus design ,photo of my hardware .... try to resolve my problem friends ....
my problem is
* i wanna to shift left to right without flickering and also
* to control data control flow . if i increase character means...
Hi dear friend...
* i am using PIC16f877A MC and
* 74HC595 for shifting ...
* 12MHz crystal frequency
* now i am giving 1 ms time delay
i wanna to scroll left to right on dot matrix display(13 characters). Actually it...
Thanks dear friends ... Now i got output with ur guidelines ,so now i can display single character . but one small issue is, it is not scrolling . . . and also when i tried to scroll three character while it making some issue .here with i added my code and design ... give idea friend ...
ya i agree sir .... i won't use watchdog timer and like special features .. so i disabled like that feature ...I configured crystal frequency 12MHz and configured Input/output ports . here i am trying to drive some character on dot matrix display .. my doubt is my program is right or wrong ...
Config setting means what sir?
we using 12MHz freq
16f877a Micro controller
if u mentioning in Programming wise means,
first we have to mention ,about port.
TRISB=0x00 // Port B is output
TRISB=0xff // Port B is input
it is right ?
Thanks for replying sir ...
display, clock and clear display functions declaration are no need ,i forget to remove that ...
I removed PORTB=0... but it will not working ...
what i do?
Hi dear friend
Already i posted my doubts ,but no one reply for that. please solve my problems.
i trying to display character in 8x8 dot matrix display using 74HC595. but i can't
here i added my code and proteus connection .please clear my doubts.
My code :
#define DS PORTD.F0
#define...
I wanna to display one string in 8x8 dot matrix display. I written one code to display 5 character ,but it does not work .so i herewith added my code and Hardware connection.
Compiler is Mikro C
Controller is PIC16f877a
Shifting reg is 74HC595
Display is 8x8
please make correction or...
