七:终极任务二：使用外部存储器，组建简易FTP文件服务器，并能正常上传下载文件。
7.1 准备
基于ftp的example和前面的入门任务和基础任务一。
添加代码
修改CMakeLists.txt为如下
set(TARGET_NAME w5x00_ftp_server)
aux_source_directory(ZLG_GUI ZLG_GUI_SOURCES)
include_directories(ZLG_GUI/include .)
add_executable(${TARGET_NAME}
${TARGET_NAME}.c
ls013.c
ls013_lcd.c
${ZLG_GUI_SOURCES}
)
target_link_libraries(${TARGET_NAME} PRIVATE
pico_stdlib
hardware_spi
hardware_dma
hardware_clocks
ETHERNET_FILES
IOLIBRARY_FILES
FTPSERVER_FILES
)
pico_enable_stdio_usb(${TARGET_NAME} 1)
pico_enable_stdio_uart(${TARGET_NAME} 0)
pico_add_extra_outputs(${TARGET_NAME})

7.3 测试
下载运行D:\BOARD\followme4\RP2040-HAT-C\build\examples\ftp\server\w5x00_ftp_server.uf2
使用FileZilla连接，可以下载上传文件
7.4 增加eeprom读写
参考以下文章使用IO模拟IIC可以驱动各种IIC设备，使用QWIIC转接板可以接各种QWIIC接口的传感器。以下在tfp基础上实现EEPROM读写。
