Example Description

This example shows how to configure the TIM peripheral to interface with a encoder sensor. The TIM3 is configured in encoder mode1: Counter counts up/down on TI2 rising edge depending on TI1 level

The TIM3 Autoreload value is set to 399, so the encoder round is 400 TIM counter clock. An update interrupt is generated each time the TIM counter reach the Autoreload value, in this example 400 TIM counter clock.

Note:

The "system_stm32f0xx.c" is generated by an automatic clock configuration tool and can be easily customized to meet user application requirements. To select different clock setup, use the "STM32F0xx_Clock_Configuration_VX.Y.Z.xls" provided with the AN4055 package available on ST Microcontrollers

Hardware and Software environment

• This example runs on STM32F0xx devices.

• This example has been tested with STMicroelectronics STM320518-EVAL and STM32072B-EVAL including respectively STM32F051R8T6 and STM32F072VBT6 devices and can be easily tailored to any other supported device and development board
