Hi all,
I have been reading the code for SPI and ENCX24J600 in the
feature-runtime-wip.
To my understanding the ENCX24J600Class::availablePackets() in
encx24j600_packet.h is not returning correct packet count value in E_STAT
address read through SPI. That may be the only reason why its not reading
furthermore packets. Is it possible to test the value returned from lower
8-bits of E_STAT by writing it through serial port? There might be
configuration problems while initializing the registers for encx24j600.
