Looking into SigmaStudio help, I have found that there is a block (on demand) for driving a stereo LED level meter using an external A6276EA chip from Allegro.

a) How can we get this block?

b) Is there a way to do a similar thing, as for example driving the A6276 output channels individually or, better, to use a standard shift-register with SPI-like interface (clock, load, data in) to connect external devices such as LED indicators and gain control to them individually? (not necessarily for audio level metering as the mentioned block does)
