Posted on October 06, 2016 at 00:39 I am trying to set up TIM4 in Encoder Mode in Nucleo F767ZI. STM32 core support for Arduino. It works with stm32 platforms. On a whim I added the code snippet below, which was from another STM32 encoder example from the mbed siteit appears to be redefining a function which was already being called somewhere in the encoder library I am using. I want to measure the speed and position of a motor with an integrated hall encoder of 6400 rising/falling edges per rotation, separated into two channels (one CH gives 3200 rising/falling edges). Dc motors are common motors you see in your houses(DC water pumps, DC fans), toys etc. However, the datasheet / programming manual is very vague on anything other than a single encoder connected to TI1/TI2 channels of a timer (EG Timer 2 Channels 1 + 2), the CubeMX software appears Measuring The Rotation Speed Using STM32 and Timer in Encoder Mode. Nucleo32-L432KC (ARM Cortex-M4 @ 80MHz) or (eBay) 2. Stm32 Nucleo-64 using the Arduino SimpleFOCShield.
