I would like to puck up this time an easy programming on MCU for child or dummies. The program is going to be a LED Blinky program, it simply blinks LED’s. Actually, you might have seen this type of articles somewhere. I tried to show an MCU programming using development environment that is a free of charge, which is being used at work in an actual environment.

I tried to measure a DMA data transfer throughput on Kinetis MCU. I was wondering how fast it is.

QN9080 has Arm Cortex-M4F core integrated, DSP instructions are available for such algorithm computation. QN9080 has a co-processor integrated as well which is called Fusion Signal Processor (FSP), it is suitable for processing an algorithm for sensor data. Thanks to FSP, the sensor algorithm processing can be done in parallel with a high priority task like Bluetooth stack processing. FSP is actually much faster than Cortex-M4F DSP instructions.

It has past a quite a long time since the last post, but I finally got time so I post a new article. This time, I introduce an unique feature, which is a power debugging on MCUXpresso IDE. The power debug doesn’t give you a powerful debugging, but you can monitor a dynamic power consumption and it is visualized on MCUXpresso window.

As a dynamic analysis method of application, I have wrote about printf debugging in the past, but this time also gives you tips about printf debugging.
