## 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

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
