Controlling speed in DC motors and position in servomotors with KSDK [FTM + GPIO]

[#1]

Hello community,

This document is the continuation of the document Line scan camera with KSDK [ADC + PIT + GPIO] which shows the ease of use of the peripheral drivers from Kinetis SDK applied to the Freescale Cup smart car. This time I bring to you a document which explains how to control the speed in DC motors and the position in servomotors with KSDK step-by-step. This document is intended to be an example for the TPM and the GPIO peripheral drivers usage.

The required material to run this project is:

• A Servomotor (the project supports up to two servomotors, one servomotor is included in the smart car kit).
• Two DC motors (included in the smart car kit).
• FRDM-KL25Z based on the Kinetis Microcontroller KL25Z.
• FRDM-TFC shield.
• Mini-USB cable.

This material can be bought in The Freescale Cup Intelligent Car Development.

   

The document Create a new KSDK 1.2.0 project in KDS 3.0.0 explains how to create a new KSDK project for the KL25Z MCU. The result of this document is the project BM-KSDK-FRDM_KL25Z.

The document Controlling speed in DC motors and position in servomotors with the FRDM-KL25Z and the Kinetis SDK [... explains how to implement an application to control the motors. The result of this document is the project BM-KSDK-FRDM_KL25Z_LINE_SCAN_CAMERA-SERVO-DC_MOTORS.
