To view and edit the device registers,
click the
(Registers) icon on the menu to the left. The Registers tab looks like the one shown
in Figure 4-9.
From this page, the user can read and
write device registers on the EVM. Here are some important notes:
- Use the Selected EVM
drop-down menu at the top to choose which device to work with on the Registers
page.
- Note, changing this here
also changes the same setting for the Configuration tab.
- Functionally, this
setting sets the default read/write address in the MCU and then reads
all register values back to update the Registers page. Note that if data
is being collected at a high frequency, then this can cause a minor
delay in the data collection. For good performance, set device settings
before starting to collect data.
- By default, all changes are
automatically written to the device. If desired, then change the Immediate
Write setting to Deferred Write to only allow writing when
ready.
- The user can modify
writable register values from any of these methods:
- Through the
widget settings in the Field View section on the
right.
- Changing the
Value directly with either hex or decimal
values.
- Double-click on
any individual bit.
- Turning on Auto Read only
updates registers in the Registers page, and not the plots in the Results
Data section.
- Leaving Auto Read
on while collecting data for plots can interfere with data collection
timing.
- For questions about a register or
register bit field, select the icon.
- For even more questions
about registers, check the data sheet.
- For convenience, register
settings can be saved and loaded back later to any device with the same register
map. To do this, go to File > Register Data, as shown in Figure 4-10.
- Press the Read All
Registers button after loading data to update the Registers page
with the actual device values in case the loaded registers were not
compatible with the connected device.
