The module displays information on the current sampling rate using pins F0-F3 on amanero. The option must be enabled in oemtools "Enable F0, F1, F2, F3".

PCM DSDOE=0
0 (F3), 0 (F2), 0(F1), 0(F0) - 32kHz
0 (F3), 0 (F2), 0(F1), 1(F0) - 44.1kHz
0 (F3), 0 (F2), 1(F1), 0(F0) - 48kHz
0 (F3), 0 (F2), 1(F1), 1(F0) - 88.2kHz

As a display, I used the most common LCD 1602A, which can display ASCII characters in 2 lines (16 characters in 1 line), each character in the form of a matrix of 5x7 pixels.


The display itself is easy to attach to this board with the controller.
