you can use 0.3E/1A ferriet bead, with 10uf & 0.1uf capacitor at both ends of bead and ground the another terminal of capacitor. this works fine for me.
Dear friends,
I am planning to start learning ARM 7 (LPC21xx) microcontroller and need a complete reference manual with explanation of all the register. especially CAN registers. and also with example programs. thank you..
hello friends... i want to design a wireless charger of 6v/1A output.... please help me out for the circuit design.. i'v tried inductive coupling to glow small led.. but its not working... i gave 20v/900A AC for primary coil and in secondary coil i just connected one LED but LED glows only when...
hello friends. i want to design digital multimeter using 8051. pls help me for doing this project, i need a schematic and program. thanks in advance. :)
i think this would help you, but this code is for 8051. i left only the delay part
IR equ P3.3
buzz equ P1.0
org 00H
mov P1,#00h
main:
jb IR,lop
lop:
jnb IR,delay
sjmp main
delay:
ret
end
everything i made it in a program itself, so whenever i want to receive or transmit a signal, i made some perfect delay for enabling the relays. that delay calculation is very important.
this program will convert binary to hex, this would help you.
#include<reg51.h>
#define input P0 //Input port to read the values of ADc
#define output P2 // Output port, connected to LED's.
sbit wr= P1^1; // Write pin. It is used to start the conversion.
sbit rd= P1^0; // Read pin. It...
im using keil compiler, and at89s52 controller... i dont have any schematic im just connecting tsop out to external interupt.. but i dont know how to get a 14 bits from rc remote and store it in controller..
