    simple query about reading and writing times

    Hi; I have a simple question: Suppose I have a processor and I want to read and write data on its internal register. Which one will take more time ? writing or reading the same amount of data ??? and why so ????? thanks for kind replies

    What ADC is a near match for 0809?

    10 or 12 bit ADC Take Pic microcontrollers, they have built in adc's of 10 bits

    USB - RS232 - RF Would this work??

    there are bluetooth rs232 devices available, I think it can very easily be used.

    proteous ADCON0 problem for pic16f887

    Hi; I am using latest version of Proteus for simulation of all 14 channels of pic16f887. I am getting a problem that when i display the ADCON0 for channel selection bits, they can not be configured for as shown in its data sheet. Does any one know whether it is a software bug of Proteus or my...

    simple dsPIC microcontroller

    Hi Tahmid; And what about the best compiler with reference to dsPIC or PIC24. Currently i have experiance of Visual C++ and little about Proton IDE that uses Basic language for programming.

    simple dsPIC microcontroller

    Thanks a lot Tamid for ur detailed answer. which series of these microcontroller would be better for me if i am interested i designing a simple data acquisition circuit which have a built in ADC'd, have high enough sampling rate and may contain a USB port. WIll be waiting for ur kind answer NAJAM

    new to pic programming , help pls

    i think Proton IDE is the most simplest and the best one. buts sorry to say that its not free.

    How to build a voltmeter using Pic16f887?

    Volt Meter Pic16f887 @hameeds01: in the case of Pic we have the choice to keep reference voltages of our own on specified pins on the controller using i thing ADCON1 and ADCON2 registers. and then u can set the reference voltages e.g. 0 and 1 volts between which the signal will converted etc 0...

    How to build a voltmeter using Pic16f887?

    Volt Meter Pic16f887 yah u r rite, the scaling factor depends upon the reference voltages. suppose ur reference voltages are 0 - 5 volts, then ur decimal output from the adc will be 0 for 0 volts and 1024 for 5 volts in the case of 10 bit adc converter. any for any other decimal value of adc...

    How to build a voltmeter using Pic16f887?

    Volt Meter Pic16f887 you will also have to perform the conversion (scaling) inside the Pic and then display it, and ur scaling depends upon ur reference voltages at the Pic
