最近开始研究了一下stm32cube,发现挺好用的,就是bug太多,经常生成的工程不能编译.
我一般选择生成makefile,这样对自动集成比较友好.方便后续迭代.
cube配置
没有硬件,电路在不断改设计(这个是我随便画得,不一定能运行,没看手册),暂定这么分配管脚.这次主要是测试编译和接口,为以后开发踩下坑
芯片支持usbfs和fdcan,可以做个canfd数据分析,省下周立功两千多大洋(感觉周立功的东西去个0差不多),vector这种级别的比不了还是买吧.
而且支持双向USBPD,可以做快充,或者大功率耗电.看了下st的pd视频,估计未来的st芯片系列都会带有这个模块.
cube坑和注意事项
- pd快充的硬件模块
ucpd必须要手动开启中断和DMA,增加USBPD中间件并不会自动配置. - GUI_INTERFACE启用后可以对PD进行debug,ST有一个上位机PD工具
- USBPD开启TRACE_EMB,并且TRACE_EMB模块打开可以在串口debug,也可以在GUI看到.
生成代码的坑
这坑就大了…
Makefile上
IDrivers/CMSIS/Include这里多一行,生成工程经常遇到,老错误了- 下面这段
LIBS = -lc -lm -lnosys \
-lUSBPDCORE_PD3_FULL_CM4_wc32.a
LIBDIR = \
-LMiddlewares/ST/STM32_USBPD_Library/Core/lib
把链接文件当库用了…应当是下面这样:
LIBS = -lc -lm -lnosys \
Middlewares/ST/STM32_USBPD_Library/Core/lib/USBPDCORE_PD3_FULL_CM4_wc32.a
LIBDIR =
3. 修改下面编译阶段,加入ccache可以加快编译,毕竟整个库几乎不用改.不然每次修改makefile都会全部重新构建.
4. cube配置后可能有重复的文件加进去,导致一堆符号重复,删除重复即可
库BUG
经过上面反复折腾,如果你在cube配置时选择双向(dual)PD你会看到下面错误:

这个问题我猜了好久,因为之前的链接库错误,我一直在找这个库在那个lib里面,就差对全系统文件进行objdump了,后来突然发现这个ManageStateDetached_SNK函数就在报错的那个文件里面.不过是这么写的
#if defined(_SNK)
static uint32_t ManageStateDetached_SNK(uint8_t PortNum)
{
看来ST是认为这个函数只有在sink时候才应该编译,但按照名字来看双向接口应该也有这个功能.于是修改成下面这样,编译之.
#if defined(_DRP) || defined(_SNK)
static uint32_t ManageStateDetached_SNK(uint8_t PortNum)
{
然后编译成功了.
不过至于能不能正常工作,这个就需要之后硬件完成后在测试了.
