Unable to Generate ADC0 pinmux code using processor expert for S32K148 EVB

Hi,

got some issue while generating processor expert code for pin configuration for ADC0 in pin mux

step i have used is :

1->opened pin mux ->selected Channel 0 PTA0 as input.

2-> cliicked on project tab --> clicked on generate processor expert code

issue -> generated code not present in pinmux.c file.

Hi@dhirajtarole

the default setting of the ADC0->Channel0 is to select PTA0 as input, so the pin_mux.c may not be changed.

Hi,

but if we select multiple pin also ,the code will not generate in pin_mux.c file.

lets assume i have selected multiple pin like

ADC0-> PTA1/PTA6/PTA7/PTB0/PTB1/PTB2/PTB3... INPUT and click on generates processor expert code

code will not generated in pin_mux.c file as well.

see generated code below:

/* MODULE pin_mux. */
#include "device_registers.h"
#include "pin_mux.h"

Hi@dhirajtarole

can you tell me whicih IDE & SDK you are using? I will double check it,

IDE - S32DS ARM 2.2

SDK - S32K148_SDK Version : 3.0.0

Hi@dhirajtarole

we can do a test to troubleshoot the problem,

1. import the sample project in the SDK,for example.

a.import the demo: hello_world_s32k148

b.made some changes,for example,we set the PTA0 to GPIO output,then generate the code.

2. Check whether the updated results have changed

hi,

For GPIO it is working, we will get a code as shown in your pin_mux.c file.

can we get same code for ADC0 in pin_mux.c ?

lets assume, we need to perform ADC operation for that we are generating ADC0 code and calling ADC0 function in the main.c file.
1.will this ADC code will run without pin_mux configuration ?
2.or for ADC , in pinmux Direction are given default(INPUT). just we need to select on which pin we want for ADC Channel (using pin/Signal Selection) ? --(AT this condition it is not generating code)

thanks,

hi,

thanks @Senlent , it is working.

could you pl find why this is not working for other pins.

And on the S32K148 EVB board pot is connected with PTC28 pin. so by using processor generate code we are unable to use that pin.

Hi@dhirajtarole

1. As we discussed before, most of the unused ports are set to ADC input by default
2. I don't quite understand your description about the PTC28 port.do you want to use this port? If yes, you can refer to adc_swtrigger_s32k148 this routine
