I'm developing a board with the 21489 and a Cortex8 micro connected by serial port and SPI port.
The 21489 have a set of modules to shape audio channels.
In which mode I could set a firmware project (on both DSP ad micro) to have a VuMeter bar on a display connected with the Cortex8 micro?
Which is the basic idea?
Which values/rgisters the micro have to request to the DSP?
Can the DSP submit data to micro just-ready to show?
What if I need to display 5 bands bars?
