This whole discussion was aiming at making a simple Musical door bell. It is definitely not good for any songs type playback. To playback such music, you will have to use a DAC (Digital-to-Analogue converter) chip such as CS4334. I have added a schematic at Making an MP3 player using STA013 & CS433...

Hi guys I'm adding the C code for playSound function. // frequency table: periods in thousands of ms #define NFREQ 7 const unsigned char t_period[NFREQ] = {132, 148, 165, 176, 198, 220, 247}; // s - Index of the sound in frequency table // d - Duration of the sound in numbers of periods // t - Dura...

you are Welcome to robot.lk. it seems you have to amplify the out put of PIC. Below cricuit is very easy to build. tryout it. lm386amp.gif I'm unable to covert this ASM code to C, because I'm busy with my studies.

First all you need to read wave file. after reading the wave file, you will get the data. send that data to pwm register or to DAC. will be get the sound on speaker. Note down the link, which tell you the wave file format. https://ccrma.stanford.edu/courses/422/projects/WaveFormat/ read the format ...

Is it possible with out ARDUINO. using only pic??

Hi, Yes, you are correct i forgot to change there I use 20MHz so i changed the value as per 20MHz = 20000000 But still the same humming sound coming. So i Tried with the one PIC Simulator which i download from Microchip site. and checked then i realized :idea: that Timer 0 is not get started timer1 ...

Hi, I made the Do Musical DoorBell with PIC 16F628 but why to waste this 18 pin PIC for just one output line so I buy 8 pin PIC 12F629 i change program as per 8 pin pic with same crystal and also code also same just changed the port address GPIO but it creates a humming sound not exactly the way it ...
