Fast Implementation of W5500 Ethernet Communication Module of STM32
W5500 Ethernet communication overall solution design
STM32F407 + W5500 with LabVIEW Client mode
HW part: STM32F407 + W5500 connected by SPI interface
SW part:
- STM32F407 + W5500
> STM32F407 Initial configuration
> Rewrite W5500’s WIZCHIP_READ(), WIZCHIP_WRITE(),
WIZCHIP_READ_BUF(), WIZCHIP_WRITE_BUF()
> W5500 Ethernet communication main program flow chart of STM32CubeMX
LabVIEW Client:
Result:
- Communication rate results before and after modifying the officially provided W5500 library function
Conclusion:
The microcontroller STM32F4 provided in this article extends the W5500 Ethernet communication rate test system, using the STM32CubeMX tool developed by ST to configure the relevant initialization of the STM32F4 chip, combined with the W550 0Officially provided library functions reduce development time and perform single-receiver and single-send data transmission, with an average The transmission rate can be stabilized at 220KB/s. Further improvements to the W5500 library function have increased the communication rate to a certain extent. The final average transmission rate can be stabilized at 414KB/s, providing users with practical reference applications.
