    Could not get CCPR1L:CCP1CON<5:4> for Pic18f452 for PWM

    Hi i need help to fully understand the following example given pulse width=44us required duty cycle=50% microcontroller operate at 4MHZ prescaler=4 pr2=value to be loaded to timer2 pr2=[pwm/(prescaler*4*TOSC)]-1 =[44X10^-6/(4*4*.25X10^-6)]-1=10 BASE ten = 0AH...

    About EASYVR Programming with C and pic16f877

    Sound recognition is not an easy job for computer,i have wrote a c# program which print what i pronounced,but the program could not recognize each word or sentences ,mostly he write it wrong,if you said mouse he might write house may be if you said mouse in the house he would write house in the...

    [SOLVED] what is pointer functions in c++

    look at this double sinf(double x1);//declaration double cosf(double x1);//declaration double tanf(double x1);//declaration int main() {double y; int i; double (*funt[3])(double f)={sinf,cosf,tanf}; double num=30; for(i=0;i<3;i++) { y=funt[i](num); } } double...

    Using a delay routine in C#

    You could make a timer,say Mytimer1,put a variable name it mycounter have it increased by one till 1000 enable this timer,then start the timer then enter an infinit loop for(;;) { if (mycounter == 999) { //do what you want to do break; } } the program...

    PCIe communication / 4DSP PCIe coomunication

    do you mean you want to send number or message to the slot of the mother board ? the slot is the place where you can insert your card,like screen card

    Question about equation for SPBRG calculation

    I am confused ,i have run the given program above and got 12 ,exactly as the book above. Now i am puzzeled by the datasheet ,it wrote if Asyncronous use Baud Rate= FOSC/(16(X+1)); DataSheet can not be generic ,any comment ?

    Question about equation for SPBRG calculation

    Re: serialport and pic16f627 This is what i have thought.the author must be mistaken. if you look at book pic project a practical approach by Hassn Parchizadah, see page 111 he found that SPBRG=12, using this equation Baud Rate= FOSC/(64(X+1)); where x= SPBRG while using equation ,Baud Rate=...

    Question about equation for SPBRG calculation

    Hi a project to Send number through serialport, using max232 and pic16f627. the given are: High data rate for sendding (BRGH=1) Asynchronous ( SYNC=0) Then according to datasheet https://ww1.microchip.com/downloads/en/DeviceDoc/40300C.pdf page 69 ,check USART Baud Rate Generator table 12.1...

    [SOLVED] From where i could find Mother board slot addresses and pin information

    Good sugesstion i have browsed the datasheet using several searching word(distance,how far,range) findding for how far it can send is important to me. i will close this post soon as solved,but if you know for how far it can send inform me either here or as a porivate message. thanks

    [SOLVED] From where i could find Mother board slot addresses and pin information

    It is a good idea to use something better, faster and cheaper, frankly I have never done a project using usb cable But it seems worth the effort, could you direct me to a project that is done using usb, at least what should I need 1-what type of pic? 2- As far as I know there is no command in c#...
