Using the Evaluation Software
4.4
Lower Part of Screen
This part of the screen contains the following checkboxes and buttons:
•
‘’Poll status’’ checkbox: Allows continuous reading of the evaluation chip status register, the state of
I/O pins, and the voltage measurement results.
•
‘’Auto write’’ checkbox: If this box is checked, any change to registers will be written to the device
immediately. Otherwise, the user must press "Write regs" button to update registers. This way, the user
can change values in several registers and update changes simultaneously.
•
‘’Update’’ button: Reads content of every register and updates screen accordingly.
•
‘’Write regs’’ button: If Auto write checkbox is disabled, the user can press this button to update the
content of every register.
The status bar at the bottom right corner of the window indicates whether or not the connection to the
evaluation board has been established, and displays information about the last register write/read
operation. Register information is given in the format: "R/WXX:YY", where first letter indicates operation
(Read or Write), XX is the register address, and YY is data.
