Another alternative is Keil MDK. www.keil.com/freescale
The Kinetis K70 is already supported with the new CMSIS-Packs.
The IDE uVison supports P&E, OpenSDA, J-Link and Keil ULINK.
The Tower K70 is supported with two examples: Blinky and RTX_Blinky. RTX is a free ARM RTOS with source code.
You can compile up to 32K code free and there is a yearly license for all Kinetis for $745.
Hello Tong Jianwu:
Just pasting here the response to your Service Request for others in doubt.
Some legacy devices will have KSDK support, but unfortunately for K70 we do not have an estimated release time yet.
But there is K70 enablement:
1) Sample code package "KINETIS_120_MHz_SC" from the next link under “Snippets, Boot Code, Headers, Monitors, etc”:
2) MQX RTOS which fully supports K70:
Once installed you can find demos in the installation paths:
You can install CodeWarrior: CodeWarrior for Microcontrollers-Eclipse IDE|Freescale
And there are some PEx examples:
- C:\Freescale\CW MCU v10.6\MCU\CodeWarrior_Examples\Processor_Expert\Kinetis\TWR-K70FN1M
About MQX RTOS starting tutorials next links in community are very useful:
