THANKS FOR YOUR REPLY


Sorry, actually the circuit must support wide ranges of transduser so that for low range transduers like 0~100 mbar and mid range...

hai HENRIK,

THANKS FOR YOUR KIND HELP.For now i don't have the datasheet,but give some time ill find the datasheet and forward to you.Actually i want to read the 4-20 mA from a...

As you said i looked at the pins and i cant find any -vref.

"The positive voltage reference can be either VDD or an external voltage source. The negative voltage reference is always connected...

hai HENRIK,

THANKS FOR YOUR SUPPORT and sorry for delayed reply.am using "long variable" so the 32bit variable fits in it.how to feed 1v? is that any voltage regulator available for...

HAI HENRIK,
thanks for your support.as you said i tried the oversampling method and it gave me a better result than the previous method i used.but i have a transduser which range...

hai Henrik,

Thanks for your suggestions.is that the communication between the eeprom and pic is very easy?what i thought is am trying to make use of the spi communication...

THANKS FOR YOUR SUGGESTION MR.HENRIK

Actually as you said the 10 bit adc gives a 0.1 resolution on 0~100bar range which is as equal to a "primary master" and thats fine,but i want...

i have already tried the internal adc but for now my project is to read (4-20mA)0-5v from a pressure transduser(0-100bar) and then conver it into pressure units .so i need more accuracy and i want to...

thanks for the compiler,but when i bought the pic kit 2 it comes with that compiler.ill try to utilize that.how to handle the timing feature on the adc-LTC2400,do you have any idea?if have then...

i now understood the use of "sck" that it is used to control the serial clk (pin) of the adc,but in the oshonsoft i cant find any command to do that.it simply got spicson and spicsoff to control the...

Hai brother,
for now i understood the differences among the instruction set on various compiler because of your reply and thanks for that.i want you to suggest me a compiler which...

why the command set changes even all the codes are in basic language.In the article they are using shiftin and shift out but my compiler uses shiftright and shiftleft,why such a difference is...

am using BASIC and oshonsoft compiler.
i tried using the internal adc and its worked but i want to communicate with external adc using spi interface.please help me my friend.

Hai friends,

am new to this world of processors,but started playing with the PIC 16f690.
for now am trying to communicate with LTC2400-24 bit ADC to the pic through the spi...
