I have written code that generates SPWM on atmega 32 at 16MHz.i intend to use Brdge configuration and to drive that i will use TC4427 and 4426 .Problem is that in my sine wave UPS there is transformer that converts 24 Volts from bridge to 220 V Ac
questions are
1LC filter should be used before...
i want to measure 220V ac my setup will b like
-->limit voltage to 2.2V-->ADC
220v->9V
-->powers uc
if DC increase say if its 250 volts then what will hapen is nstead of 9 v we will get say 10 and that variable used infront will further scale...
first there might be problem that u have not assigned any val while decleration like
unsigned char x = 0;
second connect an LED and make it turn on in inturrept function that will tell that your program runs into that function
Will this work
i want to make current meter I posted on this forum . i tried somethings but none of them worked well i plan to work on this ckt in ADC0831 datasheet .My question is that what minimum current is this ckt is capable of detecting and please tll me equation that converts ADC reading...
Hi every 1.
I want to make Multimeter capable of reading max of 30 V DC and also make current meter capable of reading 15A Max.
I have never worked on AVR or PIC.so far i have managed to make voltmeter using AT89C51 and ADC 0831 using voltage divider ckt that reads max upto 15 V. Please suggest...
data saving using 8051
there is no problem interfacing EEPROM i have done it many times, but problem is that if i have to leave system on testing and saving three values Temperature,Voltage and current in EEPROM than wont it get full and how to save it i am using AT89C52 and 24LC256 EEPROM...
