Re: VS1063 strange SD card issues

I've sent the cards your way. I have also tried two other 16GB SDHC cards. Initially I thought the VS1063 was not able to record to them, as they both seemed to freeze the device after "Init Record". But after waiting for about 2 minutes, the recording does start. I read somewhere that the VS1063 fi...

Re: VS1063 strange SD card issues

Jep, playing from the 8 GB card works. Where can I send the cards to? I'll send them right away. Btw I much appreciate your quick response and willingness to help.

VS1063 strange SD card issues

I'm running into some issues when interfacing with SD cards. I have four cards, two of which without issues. The other two don't work, but with different symptoms. Both of the not working cards are microSD cards, have significantly higher storage capacity and are SDHC devices. Working: 128 MB, full ...

Re: Problems getting started with VS1063

Newer cards have a dedicated regulator for the uSD/SD card. I'm assuming you mean newer boards here? I've attached a separate power supply and soldered a 10 µF low ESR cap close to the SD card and the voltage sag is gone. The good news is I can now make recordings with 2 out of 4 SD cards. The bad ...

Re: Problems getting started with VS1063

That seems like a logical explanation. After connection a 2V8 power supply to the board, I was able to record something successfully. Strange enough, after the first time I didn't succeed anymore. The device seems to hang after "Init Record". Checking with my scope I did see a pretty big drop in vol...

Re: Problems getting started with VS1063

Thanks for your message. After trying for some time it seems to be an intermittent issue, I have gotten it to work only once so far. Other times the device seems to freeze / crash at some point. I got it to work by 1) Programming the code from VSIDE 2) Quickly (!) connecting over UART and inserting ...

Re: Problems getting started with VS1063

I still can't get it to work.. here's what I did 1) Formatted the SD card as "FAT (default)" (I also tried FAT32) 2) Download the newest firmware that you posted this morning 3) Commented out UART_BUFFERED, and leaving COMPAT_KEYS uncommented //#define UART_BUFFERED /* Use buffered UART commands. */...

Re: Problems getting started with VS1063

Ok thanks. You said you were working on getting UART and key control to fit in the memory at the same time. Is this realized in the new version, or do I still have to disable UART?

Re: Problems getting started with VS1063

I assumed it would always output the current state, playing, recording, whatever. I realise now that assumption was false. Thanks for posting the new version!

You say it takes some time before the actual recording starts, but I assume that's in the order of a few seconds, right?

Re: Problems getting started with VS1063

Hi pasi, Thanks for your reply, it clears up some of my confusion. However I still don't understand why the device does not respond to any serial command? For example, sending "?" should make it send some status information but nothing happens. I'll try again without UART_BUFFERED defined. How long ...
