Re: VS1005 4-channel HiRes Recorder

Hello Henrik, Forgot to mention in the last post that we would also need to know for using Nand Flash as a ring buffer: What boot code and/or boot helper rescue image code might need to remain on Nand Flash and where is it located? Where are the Bad Block Tables located? Obviously, we will still nee...

Re: VS1005 4-channel HiRes Recorder

Hello Henrik, This is going to be a long and involved message; I hope I can make my answers clear. Well explained with sufficient detail. Especially significant are the details on bypassing the file system, using the battery backup ram (which we are using - now to schedule turning the device on and ...

Re: VS1005 4-channel HiRes Recorder

Hello Henrik, We could really use this uncompressed 96K recording technology on our existing VS1005g custom board design. We are already using a Spansion S34ML04G100TF100 Nand Flash with your existing SLC Nand driver k9f4g, controlled with the same hardware configuration as the Developer Board (with...

Re: MP3Model/MP3 Codec file seeking behaviour

Hello,

This behavior also drove us to look at Oog Vorbis. Customers prefers mp3. Is this new update also now part of VSOS3.57?

Thanks for the speedy rewind update!!!

Re: RDS Radio compile problem with asm files

Hi Hannu, Thanks for the idea. I copied the file to my Solution and compiled with both: #include <vs1005h.h> and with #include "vs1005h.h" and got the same results: ERRIR 102: pointer type needed for parameter 1 Old fm_function code works fine with vs1005h header file. That's the good news. Still di...

Re: RDS Radio compile problem with asm files

Hi Panu, Just #if 0 the new code and #if 1 the original code which used the call WriteIMem((void*) 0x31, ReadIMem(int0x31)); and got very different results. Now fm_function.c compiles but in both fmint.s and mac0int.s the following link error occurs Couldn't open file vs1005h.h I see these at the to...

Re: RDS Radio compile problem with asm files

Hi Panu, Thanks for the quick reply. Tried it and I got the same error message. I did not find any rogue references in my header files. But a search for WriteIMem did turn up something interesting: In imem.h [29] i find: void WriteIMem(register __i0 u_int16 addr, register __a u_int32 instr); while i...

RDS Radio compile problem with asm files

Hello, After upgrading our FM/RDS code from the original (test code) to the latest from 6-12-18 (which compiles correctly), I am having a compile problem in fm_function.c file. I have replaced the old RunIQComp/FmIQRound combination with RunIQComp.c/FmIntC.c/fmint.s combination. I am getting the fol...

Re: Need I2C Driver

Panu,

Does the GPIO2 pins have their own Bit Engine 0 and 1. From the data sheet this appears to be true, yet your post above seems to imply that only GPIO1 pins have the engine. Am I reading this correctly?

Thanks,
Scott

Re: creating mp3 device playing sound in specific time

Panu, Thanks, this clears it up. We could perhaps also integrate code into the kernel boot to detect this kind of situations. For our application, this is not really necessary. If the alarm triggered a boot sequence, we still must read a stored list of any pending alarms anyway. These alarms are to ...
