FlexIO PWM

JustMet — Thu, 14 Jul 2022 11:37:35 GMT

Hello

I am using Simulink model-based design to generate code so I tried 2 things
1st I add the FlexIO Uart Config file(
When I am using the FLexIo Uart Config file I am unable to use my IRQ handler it gives me the error exio_common.c:347: multiple definitions of `FLEXIO_IRQHandler'
I comment out my IRQ handler the code run without any error but without the handler my code is logicless
)
2nd I removed the FlexIO UART Config and run the code I get the error for Missing header file and to copy the header file into my code folder I went to the location but I didn't find the specific header file you can see it in the images I am sharing

Best regads,

Link to same question with images in same community but other section - Re: FlexIO PWM - NXP Community

Hello @JustMet ,

Could you please have a look first at the examples we provide together with our toolbox related to the FlexIO UART, and try one of the examples there on your setup?

For example you could start with fxio_uart_hello_world_s32k14x example

If you are still unable to build your example, and still facing errors, could you please send me your example?

Hope this helps,

Marius

hello @mariuslucianand

Yes, I can build examples on my setup I think it's my error on tlc file. I am trying to transmit SENT Signal from PTD0 PTD1 currently and later want to use multiple blocks to transmit SENT signal from all available FLEXIO Tx pins.

Hello,

So I updated my code, TLC and Mex file

-> in my code now instead of using

FLEXIO_IRQHandler(FlexIo_IRQN)

i am manualy calling

FLEXIO_IRQHandler1(uint32_t DATA),

this is also updated in TLC file so in tlc ->

%function Outputs(block, system) Output
%if FEVAL("mbd_s32k_is_codegen_compatible", CompiledModel.Name)
FLEXIO_IRQHandler1(%<LibBlockInputSignal(0, "", "", 0)>); %%DATA
%%<LibBlockOutputSignal(0, "", "", 0)> = returnData1(%<LibBlockInputSignal(1, "", "", 0)>); %%return Data to Output
%endif

%endfunction

also i am attaching the simulink model ,snapshot of tlc and s function c file with this post

in the model i am taking converted data from adc block and using that data for Transmiting SENT Singnal

The code is working in IAR Debugger (there i have ADC function ) in simulink i am using ADC block for adc conversion

i am initialising the clock and FLEXIO and i am getting this error and i cant seem to understand what i am missing

if i include #include "S32K144.h" file i get the error no such file or directory so i also added this file into my code folder but same error and once i remove the include i get the following error
