    Need a Help in Wind Turbine ..

    I should say that that depends on the typical wind speeds you have, on the design characteristics off the wind mill airfoils (drag and lift), and on the generator minimum and maximum shaft speeds and resistant torque... It is indeed a complex design theme... If you are planning to use a...

    Question about C language structure

    = is assignment operator, and it means that the right hand is assigned to the left hand.. == is a boolean or logic operator it compares the right hand and the left hand and returns true if values are equal or false if they are diferent. !== does not exist in C and should give a syntax error...

    diffrential equations

    When you plot the readings you have a description of what is recorded.. Unfortunately, you wont be able to predict the results for the same phenomena in different conditions for example a more complex geometry, a different material, or combination of materials, and that is why Differential...

    Question about C language structure

    Exactly as Tahmid says, if ( a == b ) { // empty } is the same thing as if ( a == b ); now about the condition inside the if(N=!0) ---> ( it means if( N = (!0) ) ) Actually that condition will always be true because you missed the boolean operator != because !0 is NOT FALSE and...

    need explanation for following system tick code of FreeRTOS

    thank you for the clarification, I also assumed that.. what I don't understand is what qualifies a task to be ready.. Is it some kind of sync signal?...

    need explanation for following system tick code of FreeRTOS

    As I understood from analyzing this piece of code: "pxReadyTasksLists[]" is an array of lists... each array position is a priority level, meaning that at each position there is a list of equal priority tasks witch are ready (although I don't understand the meaning of ready here)...

    [SOLVED] Problem ADC 16bit with Arduino using SPI.h Library

    Can you test this with cs always low? #include <SPI.h> int ss=10; void setup(){ pinMode(ss,OUTPUT); SPI.begin(); SPI.setBitOrder(MSBFIRST); Serial.begin(9600); digitalWrite(ss,LOW); } void loop(){ SPI.transfer(0x28); delay(1);//wait for drdy drop char...

    [SOLVED] Problem ADC 16bit with Arduino using SPI.h Library

    I didn't understand... 1/FFFFFFFF ??? the clock register is bidirectional ..it's size is one byte... the power on reset value (default value) is 0x85, so the reading at start up should be 0x85... if you set clock register to such a value that sets ClockDisable bit, since you don't use an...

    Help to identify component

    :) Yes ... That is also my guess.. something like this.. https://datasheet.octopart.com/ZMV933ATA-Zetex-datasheet-123346.pdf ______ I Just can't get to find them at ST..

    Help to identify component

    I agree.. seems like St Microelectronics Logo.. Looks like a Varactor (Varicap diode)

    [SOLVED] Problem ADC 16bit with Arduino using SPI.h Library

    I'm sorry.. you are right.. thanks for the correction... Anny luck with the hardware poling? I was thinking, what if you add a 1 ms delay after each CS LOW, just before communication?
