In case you have this problem with the FRDM boards: You are using the FRDM bootloader mode (it shows up as BOOTLOADER) or the MSD mode (e.g. it shows up as FRDM-KL25Z) (see OpenSDA on the Freedom KL25Z Board) and it does not respond any more, or does not work as expected, then read on…
If you are not in the academic world, then you might wonder about that ‘LaTeX‘ in the title. and no, it is not about that latex rubber material ;-), it is about ‘la-tek’ 🙂
In short, it is a programming language and tool set to ‘compile’ documents. Originally, TeX has been designed and mostly written by Donald Knuth and released in 1978. Since then, it has been evolved and TeX (or LaTeX) is widely used in academia.
Now I have implemented a watchdog with Processor Expert for my system. But what I have found out? I ended up with a looping system, and the watchdog did not fire 😦
What went wrong?
This week we were busy with building and documenting the first robots based on the Zumo Robot Chassis PCB.
The chassis is designed to hook up the FRDM-KL25Z board from Freescale. It is using parts from Pololu (chassis, motors, DC-DC converter, line sensor, H-Bridge, encoders):

In this semester course, students (and myself too, of course :-)) are building a Mini Sumo Robot. That robot is using the Freescale FRDM-KL25Z board with an ARM Cortex-M0+ on it. Today I’ll give an introduction to the ARM core to the class, and timing is right: this morning I have found an excellent overview about ARM microcontroller and tools written by Jay Carlson.: Getting Started with ARM Microcontrollers.
