canbus to usart directly

I'm using NUCLEO F103RB.

1. First install stm32CubeMX. https://www.st.com/en/embedded-s ... ia=productId=LN1897

   and install SystemWorkBench http://www.openstm32.org/HomePage

2. Use CubeMx to create project new project

   

   For me chose NUCLEO-F103RB

   

   YES

   

   Now configure the pin function. CAN+RTC+USART+WWDG

   

   also, you should take some time to look "clock" "configuration" "power calculation" is to calculate the power use for the project,most time is not that important ![image]
   project--setting

   

   project name "test4" Most important is to chose "Toolchain / IDE" to SW4STM32.........Important

   

   generate code

   

   now, finished to generate project to use. next step is to import the project to systemworkbench.

3. import project to System Work Bench. open systemworkbench, chose workpace directory. this is not that important

   import our project file--import

   in Genaral chose existing projects into workspace

   browse

   chose test4 -- open -- finish

   open the project and find main.c in while(1), add HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_SET); This means to turn on the blue led

   

   click "run"

   

   chose Ac6 STM32 C/C++ application

   

   than the blue led turn on.
