Hi all,
I'm having an occasional issue where the TRF79070A FIFO overruns. I'm hoping you can tell me why.
The SPI trace (Saleae) between TRF7970A and STM32L4 is available here
here is a screenshot:
At 3.652+s we empty the FIFO for 98 bytes but the subsequent read of the FIFO status register says there is a buffer overrun. The FIFO is 128 bytes so it's not clear to me why there is an overrun.
Another observation is that the NFC traffic seems pretty steady but then at 3.592+s it looks like it slows down a bit. I'm not sure why this happens and I'm wondering if it's causing the buffer overrun.
Any insights are greatly appreciated!
Regards,
Robert Abad
