Texas Instruments INA228 User Manual

4.2.2.3 Registers Tab
To view and edit the device registers, click the (Registers) icon on the menu on the left. The registers tab will
look similar to the one shown in Figure 4-11, depending on the device connected.
Figure 4-11. GUI Registers Tab
From this page, you can read and write device registers on the EVM. Here are some important notes:
• Use the Selected EVM drop box at the to choose which device to work with on the register map.
– Note, changing this here also changes the same setting for the Configuration tab.
– Functionally, this button sets the default read/write address in the MCU and then reads all register values
back to update the register map. Note that if data is being collected at a high frequency, then this may
cause a minor delay in the data collection. For optimal performance, set device settings before you start
collecting data.
• By default, all changes are automatically written to the device. If desired, you can change the "Immediate
Write" setting to "Deferred Write" to only allow writing when you are ready.
– You 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 clicking on any individual bit.
• Turning on "Auto Read" will only update registers in the register map, 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 4-12.
