dagakshayParticipant
F = (9/5)*C+32
f is temperature in fahrenheit and c is tempeature in degree celcius
this is the global formula….
very excatly you got struct.
dagakshayParticipantu can use RD2 its 8051 compatible ic by philips
and software for that is “flash magic”
November 26, 2010 at 7:54 am in reply to: May I get information about shaw a Hx e.g.(FF) at LCD (256) #5161dagakshayParticipantplz be more specified about your problem…..
dagakshayParticipantPlease clarify yourself.
dagakshayParticipantin ur project what xctally you are looking for. give a brif idea about your project.
dagakshayParticipanthttp://www.engbedded.com/fusecalc/
from here u can calculate ur fuse bits……
you can go on avr data sheet on page 25 there they had given all those stuff……
dagakshayParticipantlm35 itself is a temperature sensor….
interface it with microcontroller using ADC
it has a relation rise in o/p v/s tem
for more details go for the data sheet….
for ADC interfacing go to:

dagakshayParticipantin flash magic go to option-> advance optoin-> hardware config and untick “use DTR and RST……..”
then try…….
and check your baud rate, and mx232 ckt also……
let me know wearher it works…..
dagakshayParticipantare u working with 8051 or any other micro controller
for 8051 use keil compiler
and for avr use avr studio4 (there are many other too but these are more known and easy to use)
dagakshayParticipantdagakshayParticipanthello paras,
code you have to do it your self.
about loading bin file.,….
we always dump a ihex(intel hex file){eg: led.hex} file into a controller. and i xctaly dont know about at89c51 (atmel) . but you can do it with philips manufactured 8051 i tried it on P89CV51RD2 and the softwate you have to use is “flash magic.”
here i have given a ckt now u need to connect it with your microcontroller
remember:
connect Txd(max232) to Rxd(microntroller)
connect Rxd(max232) to Txd(microntroller)
make ground and supply common
and that IC P89CV51RD2 is pin compatible with ur c51 so no need to change ur cktry..
dagakshayParticipantyes it is possible to transmitee 512 channels (even more than 512)
in the case for ht12d and ht12e
you have you have 4 bits to transmmite
so you can make your combination like
D0 D1 D2 D3 work
0 0 0 0 do task 1
0 0 0 1 do task 2
similarlly u have 16 combination from 4bit at a single address
and we have 8 address lines so total 255 addresses
so we can transmits 16 * 255 signals by using ht12d and 12e itself *(but for that you need to go with microcontroller)
calculate yourself for 640 and 648…..
dagakshayParticipantthere are no of ecomm sites where u can go buy that
sp’ly try for roboshops( i mean which sales comopnents related to robotics stuff)
October 21, 2010 at 5:07 am in reply to: Circuit diagram for 4*4 keypad interfaced with P89V51RD2 #5110dagakshayParticipantgo for thz links it might help you, the pin config. for at89c51 and p89v51rd2 is same

dagakshayParticipanti am not sure but it might work with SPI interfacing and also you need to set some registers for that(might be not sure)
