This was caused by a bad soldering in the microphone wiring. Since it is a balanced microphone the interference dissapeared as soon as that was fixed.

Actually the noise got worse from putting in 100kOhm inline with iovdd. I shall get my ocilloscope out and have a look at it. From just listening to it, it sound like a square wave.

The GPIOs are pulled to gnd with 100kOhm and the buttons connects direct to IOVDD. It may be a good idea to put some resistance on the IOVDD or each GPIO separatly to keep the current limited. What size current do I get on the GPIOs without resistance? The noice gets worse the more GPIOs driven high...

Hi, The purpose of this project is to play prerecorded messages like "10 minutes to closing" in a shop in addition to the shop PA. I'm using the VS1000 module with somewhat modified software from version 0.60 on a prototype PCB. GPIO 0-2 is pulled low and keypress pulls high is used for bi...

Hi, Is there any documentation available with more or less step to step instructions covering the procedures to change the play mode on the 16 button standalone player using a 1003b chip? I have been trying to work it out reading misc posts, readme files and documentation but I think I may be missin...

Thanks for your answer. The reason for my problem was that I actually misunderstood the instructions in the Readme.txt. I was changing the .bin file name in the .bat file rather then just rename the .bin file i wanted to use into EEPROM.IMG and use EEPROM.IMG as a parameter when running the .bat fil...

Hi, I am trying to flash a 16 button stand alone player software on to a VS10xx using VS3EMU. I manage to connect to the board. I have changed to player1003butt.bin in the prom03b.bat. When i run the .bat this I get a Coff read error: Wrong magic number in the COFF header (0x2650). Do I have to make...
