K40x256 Programming guide, API configuration guide and example code for this controller

[madhusudankumar]

I newly  started working with freescale k40x256 board... I need help in getting the user programming guide for the same which contains various APIs for the programming ..I have few sample codes , but the problem which I am facing is that an API guide would help me in programming myself. Write now I am trying to understand the example code , and it is becoming very tedious. Kindly suggest any manual with API.

Thanking you

Hi,

normally NXP provide the API document right with the SW package.

for example if you use KSDK1.3 pakage, you will find the API document under

C:\Freescale\KSDK_1.3.0\doc

if you are not working with KSDK, please let me know:

which demo code do you work with? is this NXP produced demo? please point the demo download link thus we can check. thanks!

Have a great day,
Jennie Zhang

Respected Madam,

                                  I am using Code Warrior and hence the package doesnot have the necessary API.. In order to just give an idea, I am pasting on the codes to blink the LED.. I need an API pdf which could help me to understand the codes. These codes I got from vendors as test codes so I dont have hyperlink of downloadable link

#include "Events.h"

Hi,

from your code you use processor expert. so the "API" you mentioned should refer to pe component method. to check the methods usage, right click on the component, then click on "help on the component". see attached video I made.

does this answer your question?

Have a great day,
