Test Project for LAUNCHXL-F28379D & WIZnet W5500

The project was tested in Code Composer Studio v10.1.1, TI compiler v20.12.0.STS SPI frequency - 12.5 MHz To reboot the system, first press Reset on the W5500 Ethernet Shield, then on the LAUNCHXL-F28379D

Connecting W5500 Ethernet Shield to LAUNCHXL-F28379D

Description of the program F28379D

Static IPs are used, defined in the following symbols:
  • EDGE_IP?- IP KVU
  • W5500_IP?- W5500 controller IP
  • W5500_GW?- gateway
If the?DONT_RECEIVE_ONLY_SEND?symbol is?specified?, then the uint8_t [1024] array is sent once per second, representing 256 32-bit floating point numbers (a sinusoid with increasing amplitude). If the?DONT_RECEIVE_ONLY_SEND?symbol?is?not defined, then LaunchPad expects the following commands:
  • 0x04?- Sends an array uint8_t [1024] representing 256 32-bit floating point numbers (a sine wave with increasing amplitude)
  • 0x05?- Reset the amplitude of the sinusoid
