The Wiznet5k series of chips support a MACRAW mode which allows the host to send and receive Ethernet frames directly. This can be hooked into the lwIP stack to provide a full "socket" implementation using this Wiznet Ethernet device. This patch adds support for this feature. To enable the feature one must add the following to mpconfigboard.mk, or mpconfigport.mk: MICROPY_PY_WIZNET5K = 5500 and the following to mpconfigboard.h, or mpconfigport.h: #define MICROPY_PY_LWIP (1) After wiring up the module (X5=CS, X4=RST), usage on a pyboard is: import time, network nic = network.WIZNET5K(pyb.SPI(1), pyb.Pin.board.X5, pyb.Pin.board.X4) nic.active(1) while not nic.isconnected(): time.sleep_ms(50) # needed to poll the NIC print(nic.ifconfig()) Then use the socket module as usual. Compared to using the built-in TCP/IP stack on the Wiznet module, some performance is lost in MACRAW mode: with a lot of memory allocated to lwIP buffers, lwIP gives Around 750,000 bytes/sec max TCP download, compared with 1M/sec when using the TCP/IP stack on the Wiznet module. |
