Hello
I need help with enabling Pattern Match filter on ENC28J60.
I use little modified example from ENC datasheet. ENC is supposed to respond
when encounter {0x09, 0x0A, 0x0B, 0x0C, 0x0D} at the beginning of data field
of incoming packet.
Here is my code:
With this code ENC allways return "OK", no matter what is sent.
MCU is 18F46K22, at 32MHz (8MHz on board with 4xPLL enabled).
Compiler is MikroC Pro 6.62
Thanks
Refik
