I2C drivers for TRK KEA128

jashanm — Tue, 02 Jun 2015 06:36:50 GMT

hi all,

I am working on TRK KEA128, Since i need to communicate with a sensor on I2C it need the supporting drivers (like .c and .h which we use in case of gpio) which I couldnt get it on website. So can any one share it with me so that i could test it out ?

The KEA128 is now supported in the uTasker project: µTasker TRK-KEA128 support which contains most resources.

However the KEA128 is more or less the same as a KE06 so you can probably use any KE06 files to work with.

Regards

Mark

Kinetis: µTasker Kinetis support

KE: µTasker FRDM-KE02Z support / µTasker FRDM-KE02Z40M support / µTasker FRDM-KE06Z support

KEA: µTasker TRK-KEA128 support

For the complete "out-of-the-box" Kinetis experience and faster time to market

Hello Jashan M:

Attached is a driver for I2C. This driver was developed for KE devices, but as mentioned by Mark the modules are the same. If you are interested in more drivers and examples of how to use them, you can download the KEXX drivers package from the link below, called KEXX_DRIVERS_V1.2.1_DEVD under "Middleware-Device Drivers":

Freescale Freedom Development Platform for Ki|Freescale

And specifically for TRK-KEA128 there are some labs which could help you in the next link, under "Lab and Test software":

Kinetis KEA128 StarterTRAK for CAN Applicatio|Freescale

Regards!,
Jorge Gonzalez

Hi,

The example file in the KEXX_DRIVERS_V1.2.1_DEVD gives example to read and write to i2c slave address but how do i make sure i read from a particular register of the i2c slave....

hey Jorge_Gonzalez I have tried this driver in kiel Uvision 5 IDE for TRK-KEA128 board but I get lots of error which I unable to solve so I decided to write my own library for I2C and I have done with it and now I am using this library to write byte into AT24C64 EEPROM and get back same byte from AT24C64 EEPROM , I have successfully write a byte into this eeprom but while reading this byte from the eeprom I always get 0 , I don't know what is the problem I have tried each and every bit of register but I didn't understand the problem

can you please help to find error ???

Hey Jashan first of all use S32 Design studio for programming TRK-KEA128 and another input is that FRDM-KEA128 and TRK-KEA128 board having same microcontroller so there is readymade library for all the peripherals of FRDM-KEA128 board using S32 Design Studio which is working fine for TRK-KEA128 I have tested it is working fine !!!!
