Connecting W5300 to STM32F103 via FSMC interface

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,…

STM32에서 EEPROM 읽기 쓰기 오류 대응

EEPROM Read/Write를 위한 오픈 라이브러리 https://github.com/sinadarvi/SD_HAL_AT24 오픈 라이브러리 사용시 문제점 32바이트의 경계를 넘는 범위로 Read/Write를 할 때, 값이 제대로 읽고 쓰지지 않는 문제가 발생한다. 라이브러리 내부 함수에서 이런 문제를 일으키는 것으로 보인다. 해결책 EEPROM 공간이 32바이트 단위를 걸치지 않도록 Dummy 블록을 지정하는 방식으로 Read/Write 오류를 수정한다.
