Re: VS1005 Power Consumption

One thing missing from this thread is RTC power consumption from the RTC battery . We did the measurements with an LR44 battery that had a voltage of 1.56 V. We did it with one VS1005, namely the one located on my VS1005g Developer Board. VS1005 RTC powered by LR44 battery --------------------------...

Re: Latest VSOS Kernel (3.44) available here.

Hello,

here is a minor modification to VSOS, called VSOS 3.44.

The only change is to the scheduling of the Cyclic task, which could go wrong if the Cyclic task run out of CPU at any time. This has been corrected.

Kind regards,

Re: VS1053 BOB V4 SPI interface not Working.

Hello Joe! Hi, The values in registers after 0x0034 is loaded to SCI_AIADDR are SCI_MODE (0) = 0x1800 SCI_STATUS (1) = 0x0048 SCI_MODE looks good, but SCI_STATUS does not. Bit 3 should be clear. What I think is that you start loading the code, or, to be precise, disable interrupts so quickly after b...

Re: VS1053 BOB V4 SPI interface not Working.

Hello!

After you write 0x34 to SCI_AIADDR, what value do you get if you read registers SCI_MODE (0), and SCI_STATUS (1)?

Kind regards,

Re: VS1005 player and recorder

Hello! also please suggest how to control vs1005 through microcontroller The easiest way is first to control VS1005 using a terminal program and VSOS Shell, then you can use your microncontroller and UART to give the same commands. So, I suggest UART control. As for your question of how to record, y...
