KEXX_DRIVERS_V1.2.1_DEVD

IlConte — Fri, 13 Oct 2017 06:58:25 GMT

I'm starting to develop for KE04Z8 kinetis processor with FRDM-KE04Z.

I use CW 10.6 and need use a library like KEXX_DRIVERS_V1.2.1_DEVD.

After downloading it, I could not install it and use it, how do I include it?

Thanks

Stefano

Hello,

" I could not install it and use it,"

-What do you meaning it can not install? What's the error ? And it needn't install ,

just unzip it, then you can directly impor the exmaples :

KEXX_DRIVERS_V1.2.1_DEVD.zip\kexx_drv_lib\build\cw\ke04

I download it from here : FRDM-KEXX Driver Library Package , it can work well.

Yes importing the project all work !

But I need to create a new project using the library.

In this case is difficult using many include, variable etc....

I use CW10.6

The problem is that using KE04Z8 with only 8K flash, using ewl and example libriray the flash space remaning is very low.

In particular using the standard ewl library i have the map with this occupation

.text.long2str.isra.0
                0x00000a44      0x19c C:/Freescale/CW MCU v10.6.4/MCU/ARM_GCC_Support/ewl/lib/armv6-m\libc.a(printformat_.o)
.text.__pformatter_
                0x00000be0      0x428 C:/Freescale/CW MCU v10.6.4/MCU/ARM_GCC_Support/ewl/lib/armv6-m\libc.a(printformat_.o)
                0x00000be0                __pformatter_
.text.__sformatter
                0x00001008      0x698 C:/Freescale/CW MCU v10.6.4/MCU/ARM_GCC_Support/ewl/lib/armv6-m\libc.a(scanformat_.o)
                0x00001008                __sformatter
.text.isalpha 0x000016a0       0x20 C:/Freescale/CW MCU v10.6.4/MCU/ARM_GCC_Support/ewl/lib/armv6-m\libc.a(ctype_aeabi.o)
                0x000016a0                isalpha

The ewl library use many flash space condering only 8K flash max (0x2000).

The space left for the application is really too small !

I hope there is a simple solution for this problem, otherwise it is almost impossible to develop.
What library setting can I change?
Which solution do you recommend to work with this processor?

Thanks all !

Stefano

Hello Stefano,

You can use the library of ewl_noio:

the used flash size is 0x5a4 :

Hope it helps

Have a great day,
TIC
