VSDSP Forum

Hi! I have a question about SPI BOOT and DREQ mode - on the "VS1053 Simple DSP board" (as a slave) DREQ stays LOW if I short circuit GPIO0 to GND for a boot time only. Master MCU doesn't pull down DREQ - I've checked that twice. In the VS1053 DS (ver.1.13, "9.9 SPI BOOT" on p.57)...

Thanks, Panu.

I've suggested that, but it's important to know it definitely.

It seems that it is a one frame and having no tags. Hi, Zulunation. Each mp3-frame contains just 0.026 sec of sound (mostly), so "HELLO" sample contains much more samples than "a one". And it contains ID3v1 tags: "Hello", "Panu-Kristian Poiksalo", "VSDSP...

- Be very careful with the chip select signals! - Check that xCS and xDCS are never both "0" at the same time. Hi, Panu. :) Could you, please, be more specific describing this circumstance. What will this state ( xCS and xDCS are both "0" simultaneously) lead to? Could it damage...

Hi, Panu! :D Recently, I've got " VS1053b + VS1000 HiFi Recorder " board and after playing awhile I've found some "misbehaves" of the board, that I'd like to change. E.g., if 'left' or 'right' buttons are hold pressed, sound is replaced with noise (I'd like to implement a 'fast f...

...they're the "secret" part of calling the ROM... -Panu This is exactly the same I've meant - subroutines, that resides at the crystal ROM. Well, I see, there is no documentation on it. :) ...the "library search tool" found in this forum may be helpful also. -Panu Do you mean t...

Great that it works now! Yeah... it was mea culpa... :lol: Just keep a lookout for "InitHardware()" calls in the code; -Panu I've tried to find any description of InitHardware() and other subroutines like InitLayer3() , InitCommon() or InitDecode() but had no success, so is there any docu...

... Start with the "Hello World" and "Audible Hello". -Panu Thanx for the advice, Panu. I did a short trip with "Hello World", "Audible Hello" and then "Audio Effects". Third one is a kinda mysterious for me now - ... *sp = (s_int16)(((s_int32)lp[0]...

Sorry, guys! I wanted to start with " VSIDE+SimpleDSP " ASAP so much... and missed precautions made at the page 29 of the "First Steps": If the Simple DSP Board has any code loaded ... You need to solder pins to JPE and attach a jumper. With JPE shorted f/w was downloaded success...

Hi! After making an example project "Audible Hello" I've downloaded it in the VS1053 successfully, but then downloading gets impossible: http://img828.imageshack.us/img828/180/vsidedwnlderror01.th.gif The autodetection works properly: http://img641.imageshack.us/img641/3935/84195192vsidedw...
