README ====== This port is for the FRDM-K28F development board that features the MK28FN2M0VMI15 MCU. The features of the FRDM-K28F board are: o Kinetis MK28FN2M0VMI15 MCU (ARM Cortex-M4 at150 MHz, 1 MB SRAM, 2 MB flash, HS and FS USB, 169 MAPBGA package). o Kinetis K20 MCU (K20DX128VFM5) based OpenSDA circuit. o Dual-role high-speed and full-speed USB interface with the micro-B USB connector via the high-speed switch. o One 256 Mbit (32 MB) on-board QuadSPI memory at 1.8 V. o One 128 Mbit (16 MB) on-board mobile SDRAM memory at 3.3 V. o Multiple independent voltage domains: VDD_CORE, VDD, VBAT, and VDDIO_E. o FlexIO socket which enables you to connect an optional TFT Proto 5" CAPACITIVE from MikroElektronika (5" display board with capacitive touch). o Easy access to the MCU input/output through Arduino R3-compatible I/O connectors to connect external add-on boards. o Flexible power supply option—OpenSDA v2.2 USB, Kinetis K28 USB, or an external source. o FXOS8700CQ—6-axis sensor with accelerometer and magnetometer. o RGB LED. o Two mechanical push-buttons for user input and one for the reset. o Programmable OpenSDA v2.2 debug circuit supporting the DAP-Link interface software which provides: - Mass-Storage Device (MSD) flash programming interface. - CMSIS-DAP debug interface over a driverless USB HID connection providing run-control debugging and compatibility with the IDE tools. - Virtual serial port interface. - Open-source CMSIS-DAP software project.
