Do u know actually why PonyProg not work with "USB2Serial"??????????????????????
is it the fault of language in which ponyprog is written???????????????????

---------- Post added at 13:37 ---------- Previous post was at 13:34 ----------

if the developer of PonyProg redeveloped it using JAVA or Visual C++2010....then it should sloved..........i think

No, ponyprog can work with usb to serial converts but not with ordinary converters.
 

Re: Atmel microcontroller>......................

hi,i download Atmel filp.
so can u plz give me the circuit of "RS232" mode in filp.....................
thankx in advance...................

---------- Post added at 10:31 ---------- Previous post was at 10:30 ----------

clarify plz...................
 

i found this............
but in this the disadvantage is one connection from pc to uc for Programming,and another is for UART..
and philips chip it is only one ,which is UART,can do both programme&UART comm.
no Extra microcontroller needed for programming.........
just simple........
 


tnx rabin!

u can do this by using BCD concept.

i.e:----(15)decimal=(0001 0101)bcd............


now just left shift 4bit..................

"when u press 1 then
int o;
o=0000 0000 0000 0001
when u press any next key say 3
o=o<<4;
o=o|input;"
and study BCD to Binary and vice versa conversion.
u may found BCD<->binary lib in internet

hi rabin...can u give me a sample code for 4x3 keypad or atleat a pseudo code...thank you
 

i think u want to make just like A calculator.??????????
then
i think ..........
1.check (PORTB|PORTC|PORTA|PORTD)==0?????????
if yes then ur disp=0;
2.if a key is pressed..i.e it is the 1st key.
3.if again a key pressed
<<4
|input

u may use externl interrupt for this.................
"oring" all the gate input and fed to external interrupt pin........
write code in ISR......according to ur logic
