Hi,
I've tested several command and sequence combinations but final results were simply frustrating. Here goes one capture just in case some is able to figure out what's happening.
Image may be NSFW.
Clik here to view.
Traces are: yellow=SS; Blue=CLK; Pink=RF field.
Event 1)- FIFO status read followed by FIFO data read (one byte available), works correctly.
Event 2)- First two accesses are one RESET command followed by one IDLE command.
Event 2)- Next six accesses, TRANSMIT_NO_CRC command + Continuous write to TX_LENGTH_BYTE_1 + Count (LO-HI bytes, 2 bytes) + TWO bytes.
Event 3)- The transmission of "something" starts. According to TRF7970A's documentation, I think this should not happen.
Was not the FIFO cleared with the RESET command?
Thanks in advance,
Victor
