The video generation is independent, so the CPU (and interface) speed doesn't matter unless you need constant updating such as animation.

VS23Sxxx doesn't have sync inputs, so unfortunately it cannot be used for overlaid OSDs.

The values are signed, so 65498 is actually -26, and 65535 is -1. Maybe that's your issue, maybe there are other things. You also seem to be printing the one's complement of the value and not the inverted value. Another thing you may encounter: if you stop/disable/turn off and restart the ADC withou...

I am using a USB stick as storage. It is definitely able to transfer fast enough. It is transferring at USB 1.0 speed currently and it tested at 11.7Mb/s which is more than adequate, right ? Average speed isn't the only deciding factor. What's the latency? When you read a block, how long it takes t...

What's your storage? Are you getting data quickly enough?

2.4MHz SPI is plenty to send the data to vs1063.

Hi, the errors seem specific to the arduino software, so we can't really help much.

The first things to check:
- is the XTALI running, and xRESET become high, do GBUF/LEFT/RIGHT rise to 1.2V?

What is that vs1053 card you use?

You only need to send the file data, respecting DREQ. So, check your DREQ and xDCS handling. What's the bitrate and samplerate of the file, and what's the CLOCKF value you write? The default 1.0x clock can only decode the lower samplerate or mono files. The maximum SPI speed you can use also depends...

Programming through UART works the same for your own board. You need a compatible SPI FLASH (4kB block erase) and need to copy the audio module schematics so that you have access to the UART for programming the initial firmware, and preferably a way to pull xCS low during powerup so that you can pre...

Using VSIDE and USB cable I presume, or do I need a special programmer? If the module already has a firmware programmed, you can update the firmware and content using a uSD card. If the module doesn't have firmware or it is corrupted, you can program the module firmware with UART (either in VSIDE o...

What I failed to understand is how to choose between the two modes. Or does the chip accept commands both ways at the same time? The mode of operation depends on the firmware that is loaded from the beginning of the SPI FLASH. The rest of the FLASH is used for audio content. (The SPI FLASH is popul...
