It presents a simple method to implement the full and half operating modes in order to control the stepper motors @par Directory contents - inc: containing the user header files - FullHalfStepMode/inc/stm32f10x_conf.h Library Configuration files - FullHalfStepMode/inc/stm32f10x_it.h Interrupt handlers header files - FullHalfStepMode/inc/StepperMotor.h Motor control header file - src: containing the user source files - FullHalfStepMode/src/stm32f10x_it.c Interrupt handlers - FullHalfStepMode/src/main.c main program - FullHalfStepMode/src/StepperMotor.c Motor control source routines @par Hardware and Software environment - This example runs on STM32F10x High-Density, STM32F10x Medium-Density and STM32F10x Low-Density Devices. - This example has been tested with STMicroelectronics STM3210B-EVAL evaluation boards and can be easily tailored to any other supported device and development board. - STM3210B-EVAL Set-up - There is no specific hardware (single PCB board with one reference) used in this Application Note.The validation was performed using a connection between an evaluation board for the L6208N DMOS driver ( ST board)And STM3210B-EVAL (the STM32F10x controls the L6208N DMOS driver).For getting clear picture concerning the hardware connection, please refer to the Figure.8, in the current Application Note documentation. @par How to use it ? In order to load the FullHalfStepMode code, you have do the following: - EWARM: - Open the FullHalf_Step_Mode.eww workspace - In the workspace toolbar select the project config: - STM3210B-EVAL: to configure the project for STM32 Medium-density devices - Rebuild all files: Project->Rebuild all - Load project image: Project->Debug - Run program: Debug->Go(F5) - RIDE - Open the FullHalf_Step_Mode.rprj project - In the configuration toolbar(Project->properties) select the project config: - STM3210B-EVAL: to configure the project for STM32 Medium-density devices - Rebuild all files: Project->build project - Load project image: Debug->start(ctrl+D) - Run program: Debug->Run(ctrl+F9) - RVMDK - Open the FullHalf_Step_Mode.Uv2 project - In the build toolbar select the project config: - STM3210B-EVAL: to configure the project for STM32 Medium-density devices - Rebuild all files: Project->Rebuild all target files - Load project image: Debug->Start/Stop Debug Session - Run program: Debug->Run (F5) @note - Low-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. - Medium-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 32 and 128 Kbytes. - High-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 256 and 512 Kbytes. * <h2><center>&copy; COPYRIGHT 2009 STMicroelectronics</center></h2> */
