MAX7359 Evaluation Kit
Figure 1. The MAX7359 EV Kit Software Main Window
Registers
Each of the MAX7359 registers is represented on the
software’s main window (Figure 1). Each register has its
own Read and Write buttons. Clicking the Read entire
FIFO now button reads register 0x00 repeatedly, until the
FIFO indicates that all key-press events have been read.
Key Grid
Whenever a key-press event is received, the key loca-
tion is shown on the Key Grid . This grid shows eight
rows and eight columns. Register 0x02 Debounce /
Port Enable determines how many of the column pins
are taken away from the Key Grid and used for general-
purpose outputs (GPOs).
Interrupt Response
Although the PC software cannot respond to interrupts
with the speed of a true low-level hardware interrupt,
the software does offer flexibility for evaluation. The
software polls the status of the INT output pin twice
every second. The Periodic Actions checkboxes
determine what action the software will take when INT is
active.
History Window
Each register read or write event is recorded in the
scrollable History window.
