The convinient stepper motor driver for FRDM-KL25Z

kevinamadiva — Mon, 26 Jan 2015 11:51:57 GMT

Hi,

i have a KL25Z, which i want to drrive multiple stepper motors with. My issue is i need to get a steppper driver that does not need a volt- level shifter. Am requesting if sm1 has tried this out , and what driver can u recommend. I dont want an arduino shien. i need something like a DRV8825. Any help please?

Helloo Kevin,

I hope you are doing great. I have a question, do you need a driver that doesn´t have a level shifter, so the integrated circuit driver will have to have an output of the same voltage that the motor requires? I don´t know what the voltage is required for the motor.

Check the different options on the following link: http://www.freescale.com/webapp/sps/site/homepage.jsp?code=ANALOGHOME

It could be under Drivers and Switches or Engine and DC motor control. All these are integrated circuits.

The Board tools available are these: http://www.freescale.com/webapp/sps/site/overview.jsp?code=ANALOGTOOLBOX

And just to confirm, you have checked the following shield used for our Freescale Cup Challenges: Freescale Cup Motor Driver Board. You can acquire it in our www.freescale.com with the part number TFC-Shield, it comes with the FRDM-KL25Z board.

I hope this helps.

Hi DamarisOchoa maybe my question wasn't clear enough. I have a FRDM-KL25Z which av been trying to drive AT LEAST 4 Bipolar stepper motors. but i have not found the most convenient motor driver. I have a Pololu - DRV8825 Stepper Motor Driver Carrier which is causing me a lot of headache. It just doesnt work with the KL25Z. i also tested with L293D and ULN200XX which worked but required that i shift the voltage from 3v-5v in order 4 them 2 interface with the board. But now i want a dedicated stepper motor driver (with a carrier) which would interface directly with the board and work directly with the 3v logic from the board pins. I also need a driver board that doesnt sit on top of the KL25Z which will end up limiting the number of pins i use (e.g THE ARDUINO SHIELD >> FRDM-KL25Z with the Arduino Motor Shield | MCU on Eclipse). therefore i need smth very small in size even if it drives 1 stepper motor i can be able to multiply them easily without my project becoming cumbersome. I hope that is clear enough.

Regards

Hello Kevin,

I checked who can help on this question and vicentegomez suggested to take this question to the Kinetis Microcontrollers Community where engineers can support with suggestions on Stepper Motor drivers.

Hi,

You can download the example driver that is used to control the Freescale Cup Shield for the Freedom KL25Z which has on board 2 channel Motor Driver ICs (MC33887APVW). It might be helpful. Unfortunately we do not have a code driver for the bipolar stepper motors you are using.

Hope this information can help you

i just bought a few DRV8825 pololu driver chips and they work out of the box directly with the KL25Z. Worked like charm. So if it would be helpful for someone, i suggest using the DRV8825 driver chip. Thanks for the help though.... :-D
