VS1010 LQFP SAR

Hi, My project is using the QFP version of VS1010. I understand that there is a SAR. I'm hoping I can use this to monitor some board voltages such as the battery voltage on VHIGH. Whilst section 4.4 of the datasheet shows the SAR characteristics I didn't find any reference on how to use the SAR ADC....

Re: FAT External flash memory with pic18f97j60

It's possible to create a UART controlled MP3 player with the VS1010. SO if you interface via UART to the PIC you can send commands to play files etc.
I've done a couple of examples using ATMEL processor.

VS1010 Player Software

Hi, I'm currently trying to create some firmware for VS1010 LQFP. I should state from the start I'm not a Software Engineer so apologies if the my questions appear obvious. I've used the TreePlayer as a starting point and have: 1. Replaced button control with UART input - no issues 2. Setup I2S on s...

VS1010 File Position

Hi,

Having previously used VS1005 in UART mode there was data returned on file position as a percentage.
Does something similar to this exist in VS1010?

Re: VS1010 LQFP board bring up issue

Hannu,

I found the problem. A mistake on my part! I missed the need to ground the TEST pin. On most of the ASIC's I've been involved in designing, whilst we recommend TEST is grounded it doesn't need to to be. In the case of VS1010 it really does need to to be grounded.

Thanks for the support.

Re: VS1010 LQFP board bring up issue

Hi, Thanks for the reply. Regarding GPIO1_12 (next) and GPIO1_13 (pause), these are as per the schematic you provided, so 100K pull ups to IOVDD and 10k pulldown via toggle switches. IOVDD is sitting at about 3.1V but GPIO1_12 (next) and GPIO1_13 (pause) are at ~ 2.8V. Is there some internal current...

VS1010 LQFP board bring up issue

Hi, I have build a board that uses the QFP version of VS1010. The VS1010 part of this board is based on the 'vs1010_LQFP_simple_board_v10' schematic that you kindly provided. The only element of the design that I have not populated (although I have the foot print in place) is the SPI flash. As I und...

Re: VS1005 Software Reset / Read Version

Hi, Thanks for the reply. One more question. Looking at some of your band schematics I see pull-ups on the SD Card interface. They tend to be different from board to board. I don't see anything in the datasheet regarding these. Do these have some second function? or do I need them. On my PCB I have ...

VS1005 Software Reset / Read Version

Hi,

Is there a way via the UART to initiate a reset of the VS1005 or a command to read back the version of VSOS?

Re: VS1010 QFP

Thank you for a quick reply.
Do you have any sample code for the schematic you attached?
