Please help me about this problem.
I want to use sd card module and ethernet module together. My code works fine if i remove miso or vcc pins of my SD module from the board. However, if they are connected, my code doesn't work. My lcd ekran shows the requirements of my code until arrive this line "if (ether.begin(sizeof Ethernet::buffer, mymac, 10) == 0)". Then, lcd screen freezes.
