2.1 Jump Start Your Design with the MCUXpresso SDK
The MCUXpresso SDK is complimentary and includes full source code under a permissive open-source license for all hardware abstraction an peripheral driver software.
Click below to download a pre-configured SDK release for the FRDM-K22F
You can also use the online
SDK Builder to create a custom SDK package for the FRDM-K22F using the SDK builder.
2.2 Install Your Toolchain
NXP offers a complimentary toolchain called MCUXpresso IDE.
Want to use a different toolchain?
No problem, The MCUXpresso SDK includes support for other tools such as
IAR, Keil and command-line GCC.
2.3 MCUXpresso Config Tools
The MCUXpresso Config Tolls is an integrated suite of configuration tools that guides users in creating new MCUXpresso SDK projects, and also provides pin and clock tools to generate initialization C code for custom board support
The MCUXpresso Config Tools are integrated within the MCUXpresso IDE, if using MCUXpresso IDE, no additional download is needed. If using another toolchain, please consider downloading the config tools here.
2.4 PC Configuration
Many of the example applications output data over the MCU UART so you'll want to make sure that the driver for the board's virtual COM port is installed.
Before you run the driver installer, you MUST have the board plugged in to your PC.
With the serial port driver installed, run your favorite terminal application to view the serial output from the MCU's UART. Configure the terminal to 115200 baud rate, 8 data bits, no parity and 1 stop bit. To determine the port number of the FRDM-K22F's virtual COM port, open the device
manager and look under the "Ports" group.
