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 appear; 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 be working), the SPI test might show failure status. The demo

board expects an SX1239 to be identified on the SPI interface.
