VSDSP Forum

From @Hannu 's answer, it seems plugins require a uC, and cannot be used at all without a uC. Is that correct? I still don't fully understand what you're asking. vs10xx series of chips are slave decoders, they do nothing without a microcontroller (or an application loaded from SPI EEPROM/FLASH). I ...

Can you give an example of a plugin you have in mind?

To me plugins without microcontroller are useless, because without microcontroller there is no encoding or decoding going on in the first place.

I2S is fully hardware, so it can be configured and used.

Generally vs10xx applications are designed to work standalone (edit: without external uC) . They boot from SPI EEPROM and perform their own function. Plugins..., they enhance the decoder or encoder functions. They generally do not work with applications, because they use the same instruction and dat...

The vs1053b / vs1063a EQ application takes over any normal functions like decoding or encoding. You cannot have any other code or patches loaded at the same time. The main function you have available in the EQ application is analog input from stereo line input or mono mic input, performing the EQ fu...

Can an SD card act as the external SPI memory?

VS10xx cannot boot from SD. You need SPI EEPROM or SPI FLASH.

(VS1010 can boot from SD.)

"Standalone" means you don't need a microcontroller.

You're right, there is no version for vs1003b. (A direct port is not possible because the ADC is different and there is less instruction memory.)

If EQ is all you would like to run, check the vs8053b variant.

Thanks.

Btw, VS1000 applications are better placed in the System Software forum, because VS1000 / VS1005 / VS1010 are not slave decoders...

VS1000 can only boot from SPI FLASH. (SD card is only used for audio.) The boot image (actually 4 different programs) is at the start of the SPI FLASH. The USB mass storage disk starts only after this reserved area, so when you format through USB, it won't touch the reserved area. (You can program t...
