Patches and OGG Recording

Hi, since my last post i managed it to record and play several ogg files successfully but sometimes i am experiencing strange issues that must be solved before the product will reach production state. First of all: Is the patching process required after each SoftReset ? Then to the second topic: Wit...

Ogg Encoder Plugin upload behaviour

Hi its me again.. :D The audio recording with the OggEncoder plugin works somehow fine except the fact that i have to wait like 7seconds+ to initiate a recording and i think this isn't the way it should be. My LoadPlugin method does nth. more than executing the unpacking algorithm and writing uint b...

Re: Problems with OGG Vorbis Encoder

It seems like i found the major problem. When loading a plugin, we are streaming from an SD card with an Filestream and a BinaryReader. The Reader provides us with functions like ReadByte(), ReadUint16 etc. and then advances the current position in the stream automatically. But now i found out that ...

Re: Problems with OGG Vorbis Encoder

Hi, thanks for your fast answer. Decoding is working fine and I have now replaced the starting address with 0x34 manually but this makes no difference. SCI operations should work, because i am able to change the volume of the device correctly. Here is an code excerpt of the init routine: SciWrite(Sc...

Problems with OGG Vorbis Encoder

Hi, we are currently implementing our last features for our device, which uses the VS1053 as a slave decoder/encoder. We want it to record an audio signal coming through Line_In_L (we have already checked that the signal is correct) and therefore we are trying to use the OGG encoder. I've managed it...

Re: Loading plg files and audio recording

Ok then i have a question concerning the WriteVS10XXRegister(uint16 adr, uint16 val) method:
Is it an equivalent to the WriteSciRegister() method ?

Loading plg files and audio recording

Hi, i have a question concerning your RLE compressing/decompressing algorithm: First of all, why does loading a plugin take so much time ? apporx. 125kb Then it never finished in my code, although i was using your code-example which is attached to nearly every datasheet from you. The C: if (n&0x8000...

Re: WRAM reading problems

Thank you!

It's working now. But is it normal that the play procedure is finalized after i guess 3x-4x times sending the 32Byte array of endFillByte ?
But on the whole the chip is working fine!

Re: WRAM reading problems

Thanks for your fast help!

I'll try it now again, maybe my cancelling procedure is wrong...
Do i have to set the Cancle bit only or has the SDINEW bit set to one as well?

WRAM reading problems

Hi, i'm using the VS1053 for decoding purposes but i have a problem with reading from the WRAM. As i understood so far I'm ought to perform a pointer setting method with writing the adresse i want to read to the WRAMADDR register. After that i can perform a SCIRead with the Wram Adr. The result of m...
