First of all, thank you for giving me the opportunity to test this board.

I haven't tried the Freedom platform before, and I'm really not very clear about it. I look up information online. FRDM-K64F is an ultra low-cost development platform for Kinetics K64, K63 and K24 MCU. FRDM-K64F hardware specifications are compatible with Arduino ™ R3 pin layout provides rich expansion board options. FRDM-K64F is equipped with a wealth of peripherals, including 6-axis digital accelerometer and magnetometer for developing full electronic compass functions, 3-color LED for direct interaction and feedback and two user buttons, memory that can be expanded through microSD card slots, on-board Ethernet ports, connectors for Bluetooth and 2.4 GHz radio add ins, and other connection options, Rapid prototyping can be realized. FRDM-K64F platform is equipped with Freescale OpenSDAv2 embedded open source hardware serial debugging adapter running open source boot loader. This circuit provides a variety of serial communication, flash programming and operation control debugging options.

At that time, I was a little confused. No instructions. Who can tell me why so many interfaces are used? I almost got mad, and then I found that the red paper was actually a manual, which was almost thrown away by me.

• Software support and application development are provided by the Kinetics Software Development Kit (SDK). This is a comprehensive suite, including stable and reliable peripheral drivers, protocol stacks and middleware (instead of sample code packages/samples). Join the online community forum of the Kinetics software development kit to get expert opinions and support.

Baidu, this is the description of all the above interfaces.

Then I followed the instructions and came to USB to connect the computer and then plugged in the Internet cable (at the beginning, it seemed that I didn't use this, but I was used to it)

After the cable is plugged in, the green LED light indicates that the power is on, and the three color LED light on the top flashes cyclically.

My computer has an mbed USB storage disk. After opening, a webpage shortcut appears and click to open the webpage

This is the instruction page. There is a test sample helloWord in the Downloading A program column. Download the. bin file and copy it to the USB storage disk. Then click Reset to restart the project. After restarting, the red LED light flashes all the time, indicating that the project was successfully written.

This is a development community I found. There are many examples in it.

In general, this board is very interesting, but it is not suitable for the public. If you like C/C++, I want to use this board to develop interesting applications.
