Project description
Story As W5300 supports only Parallel Bus Interface to Host MCU, connecting W5300 to STM32F103 MCU needs FSMC(Flexible Static Memory Controller) interface. I’ll show you here how to configure FSMC interface for W5300 and how to set up a loopback application as an example of TCP/IP communication using W5300 Configure FSMC In Pinout and Configuration Tab, select Connectivity->FSMC and. In FSMC Mode block, click “NOR Flash/PSRAM/SRAM/ROM/LCD 3”, select “NE3” on Chip Select, “SRAM” on Memory type, “10 bits” on Address, and “16 bit” on Data. In FSMC Configuration block, change Write operation to…
