* 本帖最后由 921742079 于 2019-12-11 09:08 编辑 * 买的stm32f103vet6的带can的工控板，自己改的BSP，cubeMX配置管脚以后，测试，无法接收数据，另外一端接的usb转can的分析仪，也拿不到数据，波特率都试过了，都不行，我用的是基于313的rtt，scons --menuconfig里面，关闭了can的硬件过滤器，apb1也看了，是36的，后来发现有人说需要用新的can驱动，然后我复制github的master分支里面的drv_can.c和h，复制到项目的 libraries/HAL_Drivers/下面，但是各种编译出错，怎样才能编译通过？
