:) Hi my friends.
I've written a code to play a song file for long time on repeat mode. Normally this code work correctly without any problem but for a short time. After for example 500 repeated, the sound goes to choppy mode, but when i change the player to other song, the other song will play...
:) Hi My Friends.
I wanna to know that, what is difference between Ethernet Controller and MicroController with built-in Ethernet.
And also which one is better with the same features...
Thanks Alot...
:) Thanks for your replies. The problem solved with your help.
I used battery charger. This charger is poor but i used some filter to regulate it.
I didn't use this bypass capacitor. When i used it the noise reduced in large scale.
:) Thank you alot...
:) Hi My Friends...
I have a circuit with LM386 Amplifier to amp the signal of VS1003 Left and Right channels.
The question is, when i put the headphone cable (example iPhone 4) to the output stage, i dont hear any noise, but when i use another headphone (iPhone 5S) i hear noise of...
as you said, i've checked again and this is what i see in oscop :
Sin wave : Input : Ch1 = blue, Output : Ch2 = yellow
before setting Speaker :
after setting speaker :
my amplifier is LM386 with this schem :
in my board i removed the Gain capacitor.
so is it correct output? does the...
Thanks for your reply, I've checked it and i can hear pure whistle sound. Also i have checked my DAC with demo wave sound (16000Hz mono) and it was pretty good. But mp3 player has noisy sound.
Hello my Friends... :)
I wanna to create a MP3 Player with ARM - STM32F103RE and internal DAC. As you know this micro controller has 2 DAC that can produce sound in stereo mode in 72MHz core clock. So i choose it for my project.
As i said, i choosed this mcu and i wrote a program for decoding...
Hi Every body. :)
I have a problem to Run(Display Character on LCD) my Code of xlcd (2x16) on dsPIC30f4011. i think my delay time is wrong but i dont know what is the Correct. can Somebody help me ?
My Code:

#include <p30f4011.h>...
Hi Everybody.
can some body help me to undersntand about Opmap in Comparator mode that how is it work and often where we use it.?
i really need to know this.
thanks alot.
:)
thanks about your help, i found out my problem and solve it, i have a oscilloscope and it was not Calibration then it made me Wrong signal and wrong Voltage (Average Voltage).
hi every body.
i have a problem about Analog to digital Processing in PIC18f458.
when i want to convert , the result is wrong, and its not work true.
this is my Code :
void set_registers(void)
{
// *********************** A/D Module **************
ADCON0bits.ADON = 1; // AD ON...
