well i am using PIC18f4620 micro-controller...and i have that microchip TCP/IP stack also.. but the problem is that i exactly dont know what all stack modules i need from that stack to make a serial to ethernet converter.
i will upload my design also. But still am not able to get that whole...
hi i am designing a serial to ethernet converter by using PIC18f4620. Actually i have just started working on it. i need some help and some ideas about what all i will need for making this. i have studied ARP protocol.
please guide me if any one ..
thanx in advance[/b]
okay..thnx...n one more thing is that i am not getting how the values of TMR0L nd TMR0H registers..and when am using it in 16-bit mode..its not modifying the value of TMR0H register..actually it is writing in this register but after the overflow in TMR0L register it is not incrementing higher...
hi.. i have worked on 8051 and ARM7 controllers but right now am working on a PIC18f4620 based project and for that i need to use timers. Acutally am struck up in timers. i started with timer0 and am not able to use this timer without interrupt. so can any body give me the idea of using this...
Re: why Stack pointr of 8051 increase after pushin in sum da
hey guyz
i know all this that when we push the data in stack, the SP of 8051 increments and its reset address is 0x07 so we 've to first increment the SP & then push the data in stack as the stack address starts from 08H ......but my...
Re: why one port is made open -drain. & y to use pullup
hey thank you all for guiding me.....
anyways in addition for all the reasons u ppl mentioned i got one more reason....actually the open drain condition helps in increasing the fan in & fan out ... value of pull up resistor decide the...
Re: why one port is made open -drain. & y to use pullup
thanks a lott....
but m not able to understand it completely....can u plzzzz elaborate it a little bit ..
thanks again
hi again...
1 more doubt....
why is it so in 8051 that when we push sumthin into stack,...its SP is incremented by 1 while its just opposite in 8085 ,86 and others...
nybody can plz tell me...
thnx in advance
hey guyz... i m a newbie in embedded field...
i read bout 8051 microcontrollers... and m havin a doubt in that open drain port...
actually m not able to get the reason why it is made open drain n we 've to use pull up resistor..i mean there wud b some reason for this na...
1 reason that i...
Re: avr microcontroller
hi.....
i m a newbie in the embedded field.....(though i 've studied about 8051 & PIC microcontrollers but not made any project)
so i need a suggestion that whether i shud go for studyin AVR microcontroller or shud i first go for some project in 8051 or PIC... coz i ve...
