2.6.0.3 RTCC TEST
When RTCC tests are initiated, the LCD display will show the clock and calendar. If no
coin battery for RTCC has been installed, the time displayed will be close to the reset
time of January 1, 2012. On the other hand, if a coin battery for RTCC is installed, the
time displayed will be based on whatever is previously set, plus the time that has been
passed. Observe that the clock is advancing. Once the RTCC test is done, SW1 needs
to be pressed to move forward to the SPI test.
2.6.0.4 SPI TEST
The SPI test in hardware self-check is performed to the SPI bus that connects the
target application microcontroller and the SX1239 Receiver PICtail Daughter Board.
Therefore, the SX1239 Receiver PICtail Daughter Board must have been plugged in
before this test starts. Once the SPI test starts, the target application microcontroller
requests specific information from the SX1239 receiver through the SPI bus. If the
expected response is received, then the “Successful” status will be displayed;
otherwise, the “Fail” status will be displayed.
Note:
If a PICtail daughter board other than the SX1239 Receiver PICtail
Daughter Board is plugged into the PICtail connector, even though the SPI
bus may still work, the SPI test might show failure status. The reason is due
to the expected values to be received from the SX1239.
