4. Freescale FRDM-K64 K64 Cortex-M4 120 MHz 1 MB flash 256 KB RAM mbed
Arduino™ R3 pin layout - we can add shields
Debug connector – next to RESET

5. Board Pinout
NOTE – our Arduino shield only uses the outside rows!

6. Update the MBED driver if needed
Connect your FRDM-K64F board via the programming USB connector (next to the reset button)
Once Windows recognizes it, you should have a new drive called MBED. Open this folder.
If there is a DETAILS.TXT file on the MBED device, read it. Otherwise open mbed.htm with a text editor and look for the version number. It should be 0226.
If not, follow the directions at:
sam_grove/0226_k20dx128_k64f_0x5000.bin

7. Updated Board Should Be 0226

8. Install the Windows Driver if Needed
NOT NEEDED FOR WIN 10
Plug the FRDM board into the PC
Open Device Manager
Check ports – if you don’t see a mbed port, you need to install the Windows driver

9. Installing the Driver Follow the directions on steps 1 and 2
Follow the directions on steps 1 and 2
Note that this installer needs to be run for every mbed board that you use – it sets up a device driver for each individual serial number

10. After installing the serial port driver, you should see these four devices

11. Back to mbed
CMSIS – Cortex Microcontroller Software Interface Standard
Standard for tools to be added to mbed
expanded into other areas:
reference design software component management
reference debugger interfaces

12. Must have ARM Account

13. But CMSIS is also a Toolbox

14. CMSIS-CORE
API for the Cortex-M processor core and peripherals. It provides a standardized interface for Cortex-M0, Cortex-M0+, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-M23*, Cortex-M33*, SC000, and SC300. Included are also SIMD intrinsic functions for Cortex-M4, Cortex-M7, and Cortex M33 SIMD instructions. *ARMv8

15. CMSIS-Driver
Defines generic peripheral driver interfaces for middleware making it reusable across supported devices. The API is RTOS independent and connects microcontroller peripherals with middleware that can implement communication stacks and data storage, amongst others.

16. CMSIS-DSP
DSP Library Collection with over 60 functions for various data types: fix-point (fractional q7, q15, q31) and single precision floating-point (32-bit). The library is available for Cortex-M0, Cortex-M0+, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-M23 and Cortex-M33. The Cortex-M4, Cortex-M7, and Cortex-M33 implementations are optimized for the SIMD instruction set.

17. CMSIS-RTOS API
Common API for real-time operating systems. It provides a standardized programming interface that is portable to many RTOS and enables therefore software templates, middleware, libraries, and other components that can work across supported the RTOS systems. It provides a standardized programming interface that is portable to many RTOS, enabling software templates, middleware, libraries, and other components that can work across all supported RTOS.

18. CMSIS-Pack
Describes with a XML based package description (PDSC) file the user and device relevant parts of a file collection (called software pack) that includes source, header, and library files, documentation, Flash programming algorithms, source code templates, and example projects. Development tools and web infrastructures use the PDSC file to extract device parameters, software components, and evaluation board configurations.

19. CMSIS-SVD
System View Description for Peripherals. Describes the peripherals of a device in an XML file and can be used to create peripheral awareness in debuggers or header files with peripheral register and interrupt definitions.

20. CMSIS-DAP
Debug Access Port. Standardized firmware for a Debug Unit that connects to the CoreSight Debug Access Port. CMSIS-DAP is distributed as separate package and well suited for integration on evaluation boards. This component is provided as separate download.

21. Tomorrow
Communications!!! RTOS!!!
