Thanks, but I do not need auto transformer.
On the other hand, I have collected all these equations from some online blog helped by google. But there was no information or data about current rating or wire size, and I have created a transformer practically using 18swg, and voltage was perfect as...
I am designing a step up transformer. I have calculated all the calculation as like core area, turn per volt, P volt, S volt. All is okay. But now I need the right wire size according to my load current.
Transformer Details:
Primar volt: 130v
Secondary volt: 200v
Imax: 8A (so 8x200= 1.6KVA)...
Yes, its typing mistake here.:thumbsup:
case 9 : return 0x6F; //For 9

Hi Klaus
Multiplexing several digit (to display alphabet)
I can display same alphabets on one digit or all digit, but now i want to display 2 different alphabets on 2 different digit at the same time...
Hi Brian,
I know that it is simpler to insurt the new value directly in PORTB lines, But I want to use multiplexer so I can show other value in other digit at the same time.
I try it by adding the switch/case statement and failed in instruction steps.
unsigned short hex(unsigned short a){...
Hi everyone,
Using MikroC Pro for pic16f73, I can multiplex numbers [0-9] on 3 digit 7 segments, but can't multiplex any alphabet or any custom segments. I want to multiplex "H" and "L" in port B.
My program is:
int X; // for Analog value
unsigned short hex(unsigned short a){
switch(a){
case...
Yes, PORTB = (Hex (x%10) & 0x7F) | (y << 7); is perfectly working what I needed. Thanks you.
Now, would u like to share with me the theory of [ &0x7F and y<<7 ] as i can teach others.
Hi Brian,
Using PORTB = (Hex (x%10) & 0xEF) | (y << 7); I can separately control (0 or 1) RB7 what i needed.
But the new problem is in this way RB4 (E bit for 7 segments) is always zero and thats why E bit of 7 segment (CC) is always off, Everything else okay. so now what can i do for RB4
Hi everyone,
Using MikroC Pro to multiplexing 7 segment the written program is
PORTB = Hex (x%10);
there PORTB means RB0 to RB7 total 8 pins are includes, but I want to use only 7 pins for 7 segments RB0 to RB6, and the pin RB7 as other O/P.
As like Rb0 to Rb6 = hex (x%10) and Rb7_bit = 0 or 1...
