Building K70 MCU based data acquisition board

phyprabab — Sat, 08 Jun 2013 16:22:27 GMT

Hello!

I am an EE student that is some what new to Freescale and MQX. I am designing a board to do data acquisition and have chosen the K70 as the MCU to use (combination of ADC channels, DSP, and memory). I am working with the K70 tower schematic removing various components and adding in necessary external ADC, power, etc. Intended functionality of the K70 I need to exploit includes SPI, parallel bus, internal ADCs, and internal PWM. I am not currently interested in most of the components of the K70 tower board, so basically just stripping out unnecessary parts on the reference design.

I have been playing with the K70 tower board using MQX, awesome stuff. I want my new board to run MQX (once its completed of course!). Could anyone give me pointers, next steps, documentation or personal experiences in getting MQX running on their own board(s)?

Thank you for your time!

Hi Phy,

Check out this thread, it'll help you out: Re: MQX: Customizing a BSP for new hardware

Easiest way is to keep the clock source the same (since that can take a bit to figure out). All the other stuff is pretty straight forward. There is an app note being worked on to flesh that out, but I don't have an ETA on that at the moment.
