Application note Connecting SPI Buses shows the different alternatives for how to connect a microcontroller to a VS10xx audio coprocessor using an SPI bus. Version 1.10 of the document has been appended with VS1073 information, and particularly its new Multiple Read SCI operation that makes reading a recorded bitstream twice as fast as before.
The VS1063a datasheet has had a minor text cleanup update.
VS1053b and VS8053b datasheets have had a minor update involving how to repeatedly start and stop the "Old" SDI Sine Test.
The new VS1073 Application Note shows in generic microcontroller C code how to control the VS1073 audio coprocessor's playback and recording. This should make it easier and faster to learn the ins and outs of controlling VS1073.
There is a new application note describing the main differences between VS10XX audio coprocessors. There are also five migration guides that present summaries of things that you need to change when migrating to VS1073.
Some of the other VS1011e migration guides and application notes have also been recently updated.
A preliminary datasheet for VLSI Solution's newest audio coprocessor VS1073 has been released.
VS1010 Developer Board schematics has been updated to v2.06. VLSI Solution recommends using the new, annotated schematics as a basis for new VS1010 designs. |
