Hi Gerasin,
Answering your second question PORT_PCR_MUX(1) is a mask which writes to the MUX field on PCR register. Look for Pin Control Register n (PORTx_PCRn) in the Reference Manual. In MUX field you can write from 0 to 7 in order to select Alternative number.
In section K40 Signal Multiplexing and Pin Assignments you can see the function for each Alternative (ALTx), in this case writing 1 (0b001) to MUX field ALT1 will be selected for that pin; for most of the pins ALT0 configures them as GPIO (GeneralPurposeInput/Output).
Answering your first question, if you can´t find those files you can create them and add them to your project:
- Check this link K40: Blinking LED - The Freescale Cup Wiki where you can find the code for k40_TOWER_BOARD_SUPPORT.h and K40_TOWER_BOARD_SUPPORT.c
- In your project right click sources-->New-->new folder, then give a name to the folder. (e.g K40_SUPPORT).
- Right click on the new folder(K40_SUPPORT)-->new-->source file. Name it as K40_TOWER_BOARD_SUPPORT.c
- To the same of the last step, but now choosing header file and name it as k40_TOWER_BOARD_SUPPORT.h
- In .h file paste the code form the link and do the same with .c file. Copy the code respectively.
- Now you just need to write the #include files in each one.
- Modify function main.
- Add paths for the new folder in project properties. right click-->properties
- In the tree on your left C/C++ Build-->Settings then add the paths on ARM Compiler-->Input. Add the path for Source folder "${ProjDirPath}/Sources"
- Apply and Now compile.
Let me know if you have any problems.
Hope this helps.
Hi,
You need compile you code in Flash mode. In Flash memory your application will be there after power-up again. Check the image below:
Click on the name of the project and then this will show up.
You can check datasheet of your product and see the list of power options, you can use the USB input to power on.
