Re: VSIDE DSP Library for VS1005, VS1063, VS1053, VS1003, VS1103

Hi Henrik.

Unfortunately, also using the documentation I cannot use remez.

It is unrecognised even if I copied the right original folders and file into my cygwin home folder

Is there something I forgot or some well-known missing procedures in octave installation?

BR
Lorenzo.

Re: Register to use for custom data VS1053B and MCU

I managed in this way: In asm.s: .sect data_x,lorenzo .org 0x1000 .export _configValue _configValue: .bss 0x2 In source file .c: extern u_int16 __x configValue; For example: if(configValue == 0x01) { // Do something. } Do you think, it is a good way? Is there a better and more efficient way?

Register to use for custom data VS1053B and MCU

Hi @Pasi. I would like to have a method to let the MCU to read from one or some registers a custom value from VS1053B. I want to use my custom plugin (http://www.vsdsp-forum.com/phpbb/viewtopic.php?p=15748#p15748) to evaluate something (I don't know what yet, maybe a statistic) and to let the MCU to...

Re: DREQ always LOW with PLUGIN - Slave use case.

Another my mistake. :) Everythink is ok now. I am going now to test the solution you proposed me with DECIMATOR for 3 in order to work with 16kHz instead of 24kHz. Thanks a lot. BR, Lorenzo. P.S. Could I post my basic new plugin in order to let others, who are interested in plugin development, to us...

Re: DREQ always LOW with PLUGIN - Slave use case.

Thanks for sizeof(2*BLOCKSIZE). My stupid mistake in copy&paste. 2) Honestly I don't understand your explaination: Setting GPIO4 as output reduces to USEX(GPIO_DDR) |= (1<<4); Setting the GPIO4 high: USEX(GPIO_ODATA) |= (1<<4); Setting the GPIO4 low: USEX(GPIO_ODATA) &= ~(1<<4); Toggling GPI...

Re: DREQ always LOW with PLUGIN - Slave use case.

1) HDAT0/HDAT1 not updated: The problem was my MCU code. So I fixed it. 2) The following function still doesn't seem have effects since the signal on GPIO4, measured MCU side is always LOW. // Set up GPIO GPIO_CONFIGURE_AS_OUTPUT(GPIO4); // GPIO4 UP GPIO_SET_HIGH(GPIO4); Probably I need to do someth...
