2.10 Test Tab
The TRF7970A EVM GUI Test Tab is used to send specific command strings that the firmware supports
but that are not built into the specific protocol tabs in the GUI and to assist in understanding the finer
details of the TRF7970A EVM operations. This tab also allows retrieval of the version number of the
firmware loaded in the MSP430F2370 on the EVM. The following example show how and why test strings
might be used.
Two buttons are available for sending strings: Send and Send Raw. The Send button is used to send
complete strings (including SOF, length, etc.). The Send Raw button prepends and appends those byte
required by the MSP4340F2370 host.c file for a properly concatenated string.
A few examples of when a user would need to utilize these features would be:
1. For observing a read or write continuous to the registers of the TRF7970A during code development
with a logic analyzer. These examples are using the Send button which adds on the necessary bytes
before and after data to send strings are entered. This example is setting up the TRF7970A for full
power out and ISO15693 operation (see Figure 39 and Figure 40).
