Re: how to record my voice in Vs1003?

Thank You!
I have just one more question is it possible to force VS1003 to output mono instead of stereo? I want to connect a single (mono) amplifier with vs1003, how should i connect it? should i simply short left and right channel and use as one channel?

thanks

Re: how to record my voice in Vs1003?

Ok we can do it step by step. First create a file on the SD card. Write this data into the file: const unsigned char RIFFHeader0[] = { 'R' , 'I' , 'F' , 'F' , // Chunk ID (RIFF) 0x70, 0x70, 0x70, 0x70, // Chunk payload size (calculate after rec!) 'W' , 'A' , 'V' , 'E' , // RIFF resource format type...

Re: vs1003 spi help

Hello Panu, Thank you for reply. I checked pin continuity with VS1003 and found the SO pin was loose, so i soldered it and now I am getting value of 65535 for all registers. I don't have oscilloscope right now but I tried the SPI check, when I connect microcontrollers SDI line to GND i get reading o...

Re: Audible "Hello" example for VS1003B + Microcontroller

Hello Panu, I read the tutorial and found it useful. I am using vs1003 and powering it at 2.65v, I am using pic 3.3v microcontroller, my question is should I decrease the voltage for SPI or 3.3v is ok? I read the datasheet and it says max High-Level Input Voltage = IOVDD+0.3v and I am using a 3.3v p...
