How to use LPC-LINK2

I’m gonna show you how to use LPC-LINK2. The LPC-LINK2 is a very handy tool because it can be used as various debug probe, being very cost effective. The license is only allowed to use for NXP MCU’s, Kinetis and LPC microcontroller. If you have already bought it but you don’t make use of it to the full extent, you can refer to this post. There might be an useful information for you.

What’s the performance?
QN9080 Fusion Signal Processor

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.

CMSIS Systick

Let’s use CMSIS! Easy way to measure cycle count.

I will show you a good tip when you want to measure the time or cycles taken for your code. By means of CMSIS ( Cortex Micro-controller Software Interface and Standard) which is an application software interface for Cortex-M MCU, you can do it so easily. Here is the easy way of using CMSIS interface to measure cycles. Let’s do it.

Amazing low power Bluetooth LE

Amazing power consumption!
NXP BLE device QN9080

Bluetooth has been 19 years this year since it was officially released as ver. 1.0. And, Bluetooth low energy has been 10 years since it was released. Bluetooth classic and low energy devices have been released from many companies. Those devices diversify the features from high-performance to super low power. In these days, NXP has released their Bluetooth low energy device with BT ver. 5.0 last year.
