    How to measure electric power?

    Hi all, I want to measure output voltage, output current and output power of a 3-phase power generator, and send those data to MCU for analyzing, how can I do that ?

    Send data with one wire protocol?

    Look, in the main function are initialization of IO ports to receive external interrupts, when external interrupt is fired, then it checks if it's first or another interrupt, if it's the first interrupt then it is reset interrupt and it remain low for 480us and goes high for 30us, so the whole...

    Send data with one wire protocol?

    thnx for reply KrisBlueNZ, Actually I don't know about CAPCOM, but my programming logic is based in interrupts, so every bit received from master fires an interrupt, than I would transmit the data bit. The codes are as follows: one wire master -> reader (Arduino for avr): #include <inttypes.h>...

    Send data with one wire protocol?

    Thanks for your answers... I've an arduino code for master end, and a code for a slave also in arduino. I understood it, but the problem is that I'm not able to measure the low bus time from master, so i can't read the command by master. Do you have any idea for programming stm8s from arduino...

    Send data with one wire protocol?

    Hi there, I want to send data through one wire protocol from stm8. So, stm8 will act as one wire slave device, and send those data to another device through one wire protocol. Please if you can, tell me how to solve this problem !

    Please help finding resistance !

    Please can you tell me how to find these parameters: R1=? ; R2=? ; Re=? if Vcc=18V; Rc=2k(ohm) ; IcQ=4.8 [mA] ; VceQ=6 [V]. the circuit is: http://img18.imageshack.us/i/electrocircuit.png/ p.s. Please do it as fast as you can because I'va an exam in Suterday...

    Help finding voltage across diode

    That is easy... Just do the equivalent of current source and parallel resistor to Voltage source and series resistor . Vin=i*R R=R; and then, when Vin>0 diodes is conducting and Vout is zero ( if diode is ideal), but if Vi<0 thn diode is cut off and Vout is Vin => Vout=Vin.

    diodes conducting in different cases?

    Are you sure that this method is right? Becuase I proved this but in some cases doesn't give the right results...

    diodes conducting in different cases?

    Please, can you tell me why the diode D1 in case (a) is conducting but in case (b) it's not? And how to find all currents in this problem? notice that the only thing that are changing are resistors... the problem is in the link below...
