If the source is a leniar source i mean if O/P(A)+O/P(B)=O/P(A+B), then the total load current measured by a single CT will be sum of equal currents for both the input sources (provided the source resistance is same) .. but as vinod already mentioned, u cant measure current flowing thorugh 2...
terminate i2c bus
i think its important to terminate the communication so tat the line gets FREE, for other slaves or masters.
its imp to note tat the slave always has the right to hold the line LOW if its processing the info given by master .
a micon will ignore an interrupt when
1) if the new interrupt has lower priority than the current interrupt
in case of maskable interrupts,
1) if global interrupts are disabled
2) if the interrupt enable bit of a perticular peripheral is disabled
any interrupt with higher priority than the current interrupt can disturb the running ISR .. provided the global interrupts are enabled .. and NMI can interrupt any ISR even when the global interrupts are disabled.
Interface AC line
U hav to build a zero corssing detector circuit .. only when the voltage on the line is 0V the microcontroller can access the line .. tats the safest method to carry on power line communication.
Re: information and link regarding analog frontend design to
Hi,
Even i'm looking out for some info on analog front end .. i've selected Teridian semiconductor corp's 73M1903C .. but the information provided in the datasheet is not sufficient .. any help in this regard is highly appreciated...
