Where I can fined FRDM-K64Z QSP examples source (Not precompiled files).

Thanks Jun

I assume that you understand that KDS is new to me.

Your attached doc is helpful it and was needed to me month
ago when I started KDS.

I’m using Freescale docs and a lot of Erich “MCU on Eclipse”
I’m wasting a lot of time doing “Googling” search.

My recommendation is to prepare for unexperienced users like
me a document with collection of: How to manuals, Demos, Application notes … etc.
It will include abstract for each item and location where to find it.

My problem now is to use OpenOSD (onFRDM-K64Z board) as a UART
with RX from keyboard and TX to console (not semihosting).

I want it with Processor Expert and KSDK , I thought that “shell_test”
demo in QSP is good place to start.

Do you have other solution?

Have a nice day,

Shaul

Yes I’m familiar with this post.

Alice solve two TX options:

1. Debugger semihostig (paragraph #1). In this paragraph she needs to use Erich recommendation and modify link
   configuration.
2. printf to Terminal (paragraph #2).

In my opinion what is missing in this post is the RX option  (reception from keyboard).

Based on RX user will have a possibility to selected different activities.

May be this is the best way to solve my problem but I don’t know how to do this

Thanks

Sorry this link doesn’t help.

Different board (Tower TWR-60) & different tool chain (CW)

The first printf( “ ***** Test ******\n”) to TeraTerm

Then gets(str) does’t work and OpenOCD lose control

Hello,

Maybe this post could help you Writing my first KSDK Application in KDS - Hello World and GPIO Interrupt, it explains how to create a baremetal project from scratch that uses the printf function.

Best regards,

Earl.

Hello and thanks;

I’m interest in keyboard reading.

Without input instruction the demo runs O.K

The program crash executing read a string or char like gets(str)

And I don’t know why.

So it doesn’t solve my problem

Hello Zhang;

Thanks

Yes I’m familiar to Erich excellent posts.

This is exactly what I want to implement.

Especially with this post and my little experience I have seen problems that I can’t explain to myself.

I have to two main difficulties: one is test program and the second is project building with the tools.

Test program

The #include definition in the Test program are not clear to me:

#include "Application.h" // ?

#include

void APP_Run(void) {

int value;

char buffer[64];

for(;;) {

printf("Hello world!\r\n");

printf("Please enter a name:\n\r");

scanf("%s", buffer);

printf(" I have received: '%s'\r\n", buffer);

printf("Please enter a number:\r\n");

scanf("%i", &value);

printf(" I have received: '%i'\r\n", value);

}

}

Project Generation:

The post refers to KDS beta tools, I’m using KDS3.0, I do not know if my problems associate them to tools or I’m doing something wrong.

My assumption is that the project is generated with PE enabled and without KSDK?

Using FRDM-K64F Device is selected from Board option, but only 1200 baud is accepted.

Using FRDM-KL25Z Device has to be selected from Processor option (why)?

In generated code I don’t see bugs that are mentioned in the post

I don’t know if the bugs in “generated code” still exist in the new tools version?

After this long story I think that the Test issue is my main problem.

I wrote simple printf and scanf test. I start debug using PEmicro.

The step by step printf is outputting to console, but scanf failed and I don’t know where is the debugger.

hi

there is no FRDM-K64Z but only FRDM-K64F

you can get source code from KDSK install folder

C:\Freescale\KSDK_1.2.0\examples\frdmk64f\demo_apps

here is KSDK 1.2.0 download link:

Software Development Kit for Kinetis MCUs|Freescale

does this answer your question?

Have a great day,

Thanks;

Strange in my installation I have only fourteen examples and in yours there are sixteen.

I’m specially interest in UART implementation with RX and TX implementations something equivalent to “shell_test” demo in QSP.

I prefer to have it implemented with KDS3.0 with KSDK1.2 , I don’t want to deal with tool versions compatibilities.

Tanks again

hi

yours screenshot is correct.  the redundant her_hello_world and my_hello_word is were created by myself for testing purpose.

I also recommend you this document regarding KDS v3.0 and and KSDK v1.2.0 customized project.

How to start customized KSDK project based on KSDK demo code

can this help you?

Have a great day,
