Ethernet drivers for KL25Z and/or KL05Z?

[danreltek]

New to implementing network interfaces I'm seeking guidance on where to start.

I am currently using KDS to develop a PE project around the KL25z (but i am thinking about splitting it into 2 KL05z working together so, interested in solutions for both of these).

I simply want to add Ethernet connectivity but can't find suitable component in PE. Nor can I find example in SDK.

A nudge in the right direction would be appreciated.

Thanks

You could use an external Ethernet chip with the KL25Z, I have done this with Processor Expert, see FRDM with Arduino Ethernet Shield R3, Part 3: Embedded Web Server | MCU on Eclipse 

I hope this helps,

Hi Erich,

I have downloaded codewarrior and imported your project successfully.

I am trying to understand RTOS. I've written concurrent programs before but I'm having trouble finding where the variable AppTask is defined. It is used in the first line of APP_Run.

I presume that this is a pointer to the user-defined process that contains the infinite loop. But how does it get a value?

Thanks

Hi Dan,

maybe have a look at the ressources on the FreeRTOS web site (FreeRTOS - Quick start guide ) which has all the documentation and tutorials.

As for the AppTask(): this is a FreeRTOS task, and if you want to pass an argument it, it has a pointer to void which you can use for this. See This page describes the RTOS xTaskCreate() FreeRTOS API function which is part of the RTOS task cont... .

I hope this helps,

Erich

Thanks Erich,

I have downloaded recommended documents and begun reading. In the meantime I have a few other questions...

Arduino Ethernet shield is no longer manufactured. I found a supplier who claimed to have some so I ordered one. When it arrived I realised it was a copy called IDUINO.

It appears to be a faithful copy of the Arduino. I opted to leave the 6 pin header in but simply hooked enamelled wires around the exposed parts of the posts. Continuity tests proved connections correct and no shorts.

No MAC address is given with the device.

Q1: Do you know if anyone else used this IDUINO etherent shield and are there any pitfalls I should be aware of?

Q2: What can I do about finding the MAC address?

I've inserted a brand new Verbatim 8 GB micro SD card.

I've downloaded and installed the very latest Processor Expert components and compiled the project.

There are 2 warnings:

When I run the project, Termite displays the following:

Q3: Can you offer me any insight or solution to getting the file system to mount please?

Thanks for your prompt, unstinting and invaluable help so far. Please never leave.

Hi Dan,

Q1: I don't know that board, but as long as it is compatible, you should be able to use it. I have other clones like that one working. I suggest you compare the schematics if they are really compatible.

Q2: why do you need it?

Q3: As for the SD card: is your card properly formatted? I'm using the FatFS from Elm Chan, see FatFs - Generic FAT Filesystem Module 

I hope this helps,

Erich

Thanks Erich,

This is the direction I am leaning toward.

Hello Dan,

The kenitis L series product doesn't support Ethernet module :

Kinetis L Series Microcontrollers - Arm® Cortex™-M0+ Core|NXP 

You can choose some of  Kinetis K series , for example K64:

There is "Ethernet_LDD" component under Processor Expert, also there is Ethernet demo project

under latest SDK2.3:

under SDK2.3 package for FRDM-K64:

Hope it helps

Alice
