How do I use Processor Expert in KDS?

[jacewalton]

Using MK22FN512VLH12 board 

How do I use Processor Expert? I have GPIO configured.

....which only controls the Blue LED on my board. 

How do I set up UART. I have it configured in processor expert but what function do I used to send and revived data with?

is there a Preocessor expert document that I can learn form?

Hi Jace,

There is "Help on component " in each component , you can find the introduce and demo code :

Right click your component , then select "Help on Component":

Hope it helps

Have a great day,

This does help but not of the components that I looked at (several of them including ADC) have a typical usage.

I am using KSDK_1.3.0

when i used the newer SDK_2.1_FRDM-K22F. I cannot get any demo projects to work or even get a basic LED blink to work.

what do i do now?

Hello Jace,

Sorry the KSD_2.x doesn't support PE.

The demos all without PE, you can find under KSDK folder :

SDK_2.0_FRDM-K22F\boards\frdmk22f

Hope it helps

I have tried those ones Non of them work....

anyways about processor expert with sdk 1.3.0. I am trying to configure UART. I can get my code to compile but I cannot get any data to communicate over UART. is there any more documentation for UART. in Processor Expert? how can I learn more about how these components work and how to use them?

There no typical usage section in this component. I'll attach my project to my original post if you could check out what my problem is. thanks!

Hello Jace,

- Only the Processor Expert without SDK has "Typical Usage", the PE with SDK  hasn't .

- When use KSDK, the API on PE is the same with KSDK without PE, so you can refer to the KSDK API RM:

KSDK_1.3.0\doc\Kinetis SDK v.1.3 API Reference Manual.pdf

And  the demo under KSDK:  KSDK_1.3.0\examples

that helps but am running into problems

this is my code from examples in the pdf 73.6.5 UART Transfers

uint8_t sourceBuff[4] = "asdf"; // sourceBuff can be filled out with desired data
uint8_t readBuffer[10] = {0}; // readBuffer gets filled with UART_DRV_ReceiveData function
uint32_t byteCount = sizeof(sourceBuff);
uint32_t rxRemainingSize = sizeof(readBuffer);
uint8_t* psourceBuff = &sourceBuff;
uint8_t tx_size = sizeof(data);

UART_DRV_SendDataBlocking(1, psourceBuff, byteCount, 1);
psourceBuff++;

The output is 

aaaaaaaaaaaaaaaaaaaaaaaaaaaassssssssssssssssssssssssddddddddddddddddddddddddffffffffffffffffffffffff

when do do not increment the psourceBuff I get

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

8 characters at a time. 

Is there something else I am supposed to do with this?

Hello Jace,

Please first test the demo which used the function UART_DRV_SendDataBlocking() :

KSDK_1.3.0\examples\frdmk22f\driver_examples\uart\uart_blocking

If it can work well, you can refer to .
