STM32CubeMX and Quadrature Encoder

I am new to ARM and STM32CubeMX

My goal is to use this very interesting board

http://www.st.com/en/evaluation-tools/32f429idiscovery.html

and use one internal 16bit counter for time and one 16bit counter for QEI

(QEI=Quadrature Encoder to track angle of crankshaft)

These two counters should have an external reset to zero when each new revolution starts

The datasheet

http://www.st.com/resource/en/datasheet/stm32f429zi.pdf

   says:

Up to 17 timers: up to twelve 16-bit and two 32-

bit timers up to 180 MHz, each with up to 4

IC/OC/PWM or pulse counter and quadrature

(incremental) encoder input

STM32CubeMX is such a great and unique utility and it can not only handle the chip but also the entire board

STM32F429I-DISC1.  This is fascinating. 

Still I am lost here as it is my first use of  STM32CubeMX

Can anybody tell how to do and also indicate  the code needed to read the counters in a C -loop,

An image is enclosed - I am also looking for a way to program the card with

Thanks and best regards

Hello

Ovelius.Bengt

,

• I advise you to download the

  http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-embedded-software/stm32cubef4.html

  package . There is an example entitled 'TIM_Encoder' under the path below: 'STM32Cube_FW_F4_V1.0\Projects\STM324x9I_EVAL\Examples\TIM'This example shows how to configure the TIM1 peripheral in encoder mode to determinate the rotation direction.You may take it as a reference.

• Since it's you first time using the CubeMx tool, I recommend to :

  • Watch the '

    http://www.st.com/content/st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-configurators-and-code-generators/stm32cubemx.html

    ' video available on ST website;
  • Have a look at '

    https://community.st.com/docs/DOC-1203-how-to-create-stm32cubemx-project

    ' which is a tutorial to create your own project using STM32CubeMX.

May this help you

Best regards,

Khouloud.
