How to use ros and stm32 communication
I would like to use stm32 to write the motor driver, use ROS to control, but I do not know how to use rosserial and stm32 communication.

Hello,
It will depend on which framework you use to program your microcontroller.
For example there is already rossserial-mbed
that works with boards supported by mbed.
If you are not using mbed, you have to create the interface in the hardware file. Basically, you have to provide a method to write a byte on a buffered serial port, a method to read a byte from a buffered serial port and a method to give the time elapsed since the beginning of the program in milliseconds.
For example :
Everything is explained in the wiki.

Thanks very much,I have found rosserial_stm32f1 package(https://github.com/spiralray/stm32f1_rosserial.git),but this project has some error when i run it .So i want to move roslib in this project to stm32 stlibrary,then using topic communicate with ros,What do you think about it?
I have never used stm32plus so I cannot help you with this library. In the meantime, I have fixed the issue with the one using ChibiOS. And I am using it successfully right now ( https://github.com/romainreignier/rob... ).
I can give you a simple example on how to run rosserial with ChibiOS but the difficulty is to use the several stm32 peripherals. No, I think, the best for you is to create a rosserial hardware file for the stm32 environnement you are used to. Maybe I can help you. Whick frameworks it is?
Ok but which library do you use to program it?
The easiest way is to use the Arduino port for STM32F1 from stm32duino.
I have just added support for it in rosserial
, I hope it will be merged soon (PR).
