Micromedia+ PIC32MX7 and Sigfox click

[heliop]

Hi,

I´m trying to run sigfox click example with mikromedia+ with the shield for pic32mx7. I create a new board definition file compatible with the shield but when I run click_Sigfox_PIC32 example it get stuck in the function sigfox_init().


I attached the board files it´s the only files I changed.

Thank you,

Hi,

Could you please attach the photo of your connection ?

Hello,

SigFox Click communicates via SPI. Have you checked that you initialized SPI properly?
Which SPI module are you using?

Kind regards,

Hi,

I´m using SPI 1 and in the oscilloscope I can see communication from pic32(CLK and DO) but no answer from sigfox click.



Thank you,

Hello,

Everything in the files seems to be correct.
I will test out Sigfox click with your board def files on mm+ for PIC32MX and I will let you know what happens.

Kind regards,

Hi,

Could you send me a screenshot of your Library Manager, the section where the mikroBUS Board Definition API is, so I can see which library you ticked?

Kind regards,

Hi,

I´m using easypicfusion but I include the files I edit

#include "__epf_generic_GPIO.c"

#ifdef ENABLE_SPI
#include "__epf_generic_SPI.c"
#endif
#ifdef ENABLE_UART
#include "__epf_generic_UART.c"
#endif
#ifdef ENABLE_LOG
#include "__epf_generic_LOG.c"
#endif

Thank you,

Hi,

But have you edited the file called easypicfusion_v7_P32MX795F512L.c?
The library uses this file and not the generic easypicfusion one.

Kind regards,

Hi,

Yes I edited easypicfusion_v7_P32MX795F512L.c

Hi Hélio,

Does the MCU completely freeze at the sigfox_init function, or does the code go through but Sigfox just fails to initialize?
How are you monitoring the code?
Have you tried other mikroBUS sockets?

Kind regards,

[heliop]

Hi,

The MCU completely freeze at the sigfox_init function.
I´m monitoring the code with breakpoints.
I only use mikroBUS1 socket because they share the same SPI bus the only difference is CS.


Thank you,

Hi,

Are you using hardware debugger?
RB6 and RB7 pins are used for programming and debugging and at the same time they are CS and RST on mikroBUS where you are trying to use SigFox Click.
I tried the example code and the MCU doesn't freeze, the code goes through, however I am not able to debug for above mentioned reasons.

Kind regards,

[heliop]

I will try without the debugger and I let you know if it works.



Thank you,
