I had a little time away from work and social life to hack together a custom test PCB circuit for the 32 pin kl24z QFN chip. This is just a board to expose the pins and provide SWD programming interface as well as provide 3.3v power. I have some separate power supply circuit drawing power […]

I got hold of some KL24Z 64K 32-pin microcontrollers at around the same time I got the Kinetis FRDM-KL25Z and FRDM-KL05Z freedom boards. After playing with the KL25Z board for a while, basically trying different kinds of toolchains and Eclipse, I think its time to make some custom PCB prototypes with the kl24 chips, and […]

Join me as I enjoy mbedding!! 😉 The mbed platform contains the libraries you need to set up a project for ARM microcontrollers, including the FRDM-KL25Z… The Application Programming Interfaces (API’s) above the Hardware abstraction Layer (HAL) that make the process of creating an embedded application trivial. You merely just write C++ code in your main […]

I am on a rampage to find a way to program and debug Freescale chips without using a vendor IDE. Well, until such a time as when i find a working cmsis-dap deburger, at least i can use a bare-metal start code and learn the arm architecture. Pre-requisites: Install gtkterm $ sudo apt-get install gtkterm […]

NB: this post has been updated since openocd now implements swd using hidapi and libusb. Before I dare start reading the mcu manuals, I wanted to just be able to build code, flash and debug on the Freescale FRDM-KL25Z without purchasing software, on Linux. I have read many blogs and here is a summary of […]

I have been looking for alternative micro-controller chips for small low cost embedded applications, mostly for teaching purposes. As it happened, our electronics thematic section at the Physics Department purchased some new KITs from Freescale. The good news is that they are ARM-based micros. I have been looking forward to going that way eventually, so […]
