HELLO, AnjanaM_61 BoonT_56 KeTa_1341526
i am trying to do the process mentioned below.
Go to Project and select Properties. Expand C/C++ Build and choose Settings. Under the Tool settings tab expand GCC Linker and select Libraries. At the right of the window, add a library named m at Libraries (-l).
As you can see in attached file, there is no Tool Setting?
Please help.
Thank you.

Hi AkJa_4647796 ,
The one in the other thread was for Modus Tool box. Please note CYBT-343026 is now supported in Modus Tool box.
So you can try MTB as well.
I have not tried any external math libs. However below is the general steps to add external library file to WICED
- Copy xxxx.a to /20706-A2_Bluetooth/Wiced-BT/tier2/brcm/libraries/lib/20703. You can directly copy paste the file into the folder using WICED GUI, look for the library folder under WICED (Be careful there is another “library” folder directly under /20706-A2_Bluetooth don’t put the file there)
- Copy the xxx.h into your project folder and include it into your source fie by using #include “xxxx.h”.
- Update your make file to include xxxx.a library by adding following line to your make file.
APP_PATCHES_AND_LIBS += xxxx.a
Could you please try these steps and see if it works ?
Q) if log function doesnt exits then what should i do? what other oprtion i can use?
A) Either you have to use a external math lib or custom function to implement the functionality.

Anjana

Hello AnjanaM_61,
Thank you for your response.
I did as you said,
1. Copy lib_fixmath.a to /20706-A2_Bluetooth/Wiced-BT/tier2/brcm/libraries/lib/20703
2. In libfixmath source directory. (file attached below)
Header files: libfixmath.h fix16.h fract32.h int64.h uint32.h (5 in total) . I copy all the header file to 20706-A2_Bluetooth\include
Source files: fix16.c fix16_exp.c fix16_sqrt.c fix16_str.c fix16_trig.c fract32.c uint32.c (totally 7)
I am not getting in which library folder i have to include it?
a. C:\Users\abc\Documents\WICED-Studio-6.4\20706-A2_Bluetooth\libraries ?
b. C:\Users\abc\Documents\WICED-Studio-6.4\20706-A2_Bluetooth\Debug\libraries
c. C:\Users\abc\Documents\WICED-Studio-6.4\20706-A2_Bluetooth\Release1\libraries ?
3. what i did is i all all the .c file into my project. and updated the makefile.mk file. As you can see in triumph >> adc_read project.
I am getting error as
make.exe[1]: *** No rule to make target '../../build/adc_read-CYBT_343026_EVAL-rom-ram-Wiced-release/fix16_32.o', needed by '../../build/adc_read-CYBT_343026_EVAL-rom-ram-Wiced-release/lib_installer.c'. Stop.
make.exe[1]: *** Waiting for unfinished jobs....
make: *** [triumph.adc_read-CYBT_343026_EVAL] Error 2
Makefile:552: recipe for target 'triumph.adc_read-CYBT_343026_EVAL' failed
what is fix16_32.o file?
in libfixmath zip files there is a makefile in which OBJ = fix16.o fix16_exp.o fix16_sqrt.o fix16_str.o fix16_trig.o fract32.o uint32.o this is included. Do i need to copy this file in my project and where?
Thank You.

Hi AkJa_4647796 ,
I am not sure libfixmath files are compatible with WICED studio. I will try at my side and will confirm.
Meanwhile did you tried adding libm.a ?

Anjana

Hello AnjanaM_61
Yes i tried all steps using libm.a also.
1. Copy libm.a to /20706-A2_Bluetooth/Wiced-BT/tier2/brcm/libraries/lib/20703
2. APP_PATCHES_AND_LIBS += libm.a and adding #include "math.h" in hal_adc.c
3. Go to Project and select Properties. Expand C/C++ Build and choose Settings. Under the Tool settings tab expand GCC Linker and select Libraries. At the right of the window, add a library named m at Libraries (-l).
Still i am getting error?
13:43:32 **** Build of configuration Release1 for project 20706-A2_Bluetooth ****

Hi AkJa_4647796 ,
Let me try at my side , give me one day.
However I doubt your error is not related to adding libs.
Can you just try download any other existing demo to 343026 ? say hello_sensor?
Hope you have included the platform files for CYBT-343026 : Platform Files for CYBT-343026-EVAL – KBA221025

Anjana

Hello AnjanaM_61 ,
Yes, i have followed all the step mentioned in Platform Files for CYBT-343026-EVAL – KBA221025
Currently using the same platform files. Even if i use hello_sensor code still get the same error.
Initially i didn't have any TOOL setting. as you can see in image below
What i did was, Go to Project and select Properties. Expand C/C++ Build and choose Settings. In setting window UNDER CONFIGURATION -->> Manage Configuration
IN pop \up window, Selecting NEW. A new windo appears.
In Import Predefined menu, selecting Executable > Cross ARM GCC > Debug.
Then i got Tool Setting option, so then, i can add m library in linker.(this is how i added m library, was it right?)
But i have some doubt, in Toolchains -->> Toolchain path is empty.
i tried adding GNU arm paths aslo
C:\Users\abc\Documents\WICED-Studio-6.4\20706-A2_Bluetooth\Debug\wiced_tools\ARM_GNU\
C:\Users\abc\Documents\WICED-Studio-6.4\20706-A2_Bluetooth\Release1\wiced_tools\ARM_GNU\
But still end up getting errors.
Thank You.

Hi Hi AkJa_4647796 ,,
Please don't do any change in the tool settings .
Please keep the default settings , add platform files as per the KBA and only follow the steps mentioned in previous response. Copying it below :
below is the general steps to add external library file to WICED
- Copy xxxx.a to /20706-A2_Bluetooth/Wiced-BT/tier2/brcm/libraries/lib/20703. You can directly copy paste the file into the folder using WICED GUI, look for the library folder under WICED (Be careful there is another “library” folder directly under /20706-A2_Bluetooth don’t put the file there)
- Copy the xxx.h into your project folder and include it into your source fie by using #include “xxxx.h”.
- Update your make file to include xxxx.a library by adding following line to your make file.
APP_PATCHES_AND_LIBS += xxxx.a
Could you please try these steps and see if it works ?

Hello AnjanaM_61,
I am trying to use this function.
WICED_BT_TRACE("log : %s\r\n\n", temp_val);
sprintf("%9.3f",temp_val);
i am getting error as
hal_adc.c: In function 'seconds_app_timer_cb':
./../../../wiced_btsdk/dev-kit/baselib/20706A2/WICED/common/spar_utils.h:55:17: warning: implicit declaration of function '__2sprintf'; did you mean 'sprintf'? [-Wimplicit-function-declaration]
#define sprintf __2sprintf
^
hal_adc.c:262:5: note: in expansion of macro 'sprintf'
sprintf("%9.3f",temp_val);
^~~~~~~
As you stated
sprintf(float_txt"%9.3f",(float)log(wiced_timer_count));
what is float_txt?
As per the snip/hal/gpio app;
the output in putty terminal is shown below.
I think the module is getting reset?
Thank You.

Hi AkJa_4647796 ,
I am sorry, float is not supported in our SDK for our BT chips .
Instead of sprintf , please use snprintf

Hi AkJa_4647796 ,
We have never noticed float_txt . If possible please share the complete code , I shall check it.
However As I mentioned before float is anyway not supported on 20706 SDK.

Anjana
