The firmware includes several command formats that are used by the RFIC Design
Assistant utility program to read and write parameters to the TRC105 configuration
registers and to send and receive terminal mode messages. Table 6 summarizes
several commands that are useful for proof-of-concept testing.

Custom Firmware Development Support
The 10-pin programming header on the interface board is compatible with the Silicon
Labs development tools for the C8051F310 microcontroller. This allows the user to
develop and test custom firmware for use with the TRC105.

Write register rr with data dd, where rr and dd are two
character hex values. For example, write 0x80 to register
0x01 is formatted as W0108.
The DR-TRC105 radio board must be in terminal mode, as
discussed in Table 5 above. The user’s message, up to 63
bytes, must be preceded with an ASCII 0x02 start-of-text
character, and followed by an ASCII 0x03 end-of-text
character. For example, the string of hex characters to
send Hello in ASCII is: 0248656C6C6F03
When the example string above is output by the receiving
node, an ASCII carriage return - line feed is added as
follows: 0248656C6C6F030D0A
