如何使用函数指针作为参数的函数

更新：我注意到我忘记在main.c中包含app.h文件，即使它包含在项目中（还有一个问题，但是还有一天）。项目现在构建，但是带有警告……src/main.c:78：警告：（359）指针类型之间的非法转换。希望有人能告诉我为什么。试着在工作中做一个项目，测试PCB上的继电器。他们在4个银行中，有一个使用SPI的继电器驱动器/锁存器和一个芯片选择线。我有四个函数向这些库发送数据，每个选择行一个。这个函数有一个函数指针作为参数。我有一个函数测试所有的库。我已经包括了源代码和构建输出的文本文件。谢谢你的帮助！上传修改文件的问题。再试一次

    Update: I noticed I forgot to include my app.h file in the main.c even though it was included in the project (another question there but for another day). Project now builds but with warnings ..
src/main.c:78: warning: (359) illegal conversion between pointer types
Would appreciate anyone cluing me in as to why.


Trying to do a project at work that tests relays on a PCB.
They are in 4 banks with a relay driver/latch using SPI and a chip select line.
I have four functions that send data to these, one for each select line.
I have one function that tests one of these banks at a time, given which select line to use. This is the function that has a function pointer as a parameter.
I have one function that tests all of the banks.


I've included source code and text file of output from build.
Thanks for the help!

having issues uploading revised files .. will try once more
