STM32F091RC DAC PINA4 PINA5 not working

‎2023-09-23 09:37 AM

I have been following mastering stm32 book for a while now and checking out the tutorials from the st channel.

I was following the dac tutorial and I had a problem with outputting analog signals in pin A4.

I use eclipse IDE and i am imporing cube-mx files to the default stm project created in eclipse with a tool called CubeMXImporter.

So far, i didn't have any problem with the tool so I really don't know the reason.

my main.c file and hal_msp file is attached below if you would like to take a look.

Well, turns out that PA5 is actually connected to PD13 and the signal is outputted in that pin. But I really don't know why PA5 pin doesn't show it up.

When i have debug the code, i realized that the execution stucks at

__weak uint32_t HAL_GetTick(void)

{

return uwTick;

}

i really don't know whats happening since i am a beginner.

Hello @roboticsdev 

I think it can be a clock configuration problem. Can you share your .ioc file.

Also, is going to be better if you start your project from one of those two ready to use DAC exemples. Than, you can add other parts (UART,...).

Best regards.

Hello, I searched my project directory with
find . -name *.ioc  but i couldn't find any file with .ioc extension .

by the way, my project format is sw4stm32 and i am using the last version of MX that supports this.

What I'm asking for is the CubeMX configuration of your project.

the same codes, except, pin_a5 is set as the output channel in this example, it also doesn't work like pa4.

By the way, I suggest you to use ST tools ( CubeMX and CubeIDE). To migrate your project from SW4STM32 to CubeIDE, you can refer to the UM2579.

Best regards.

Hello, thanks for the help really, i really don't know the reason, but PA2 pin show the output in DAC and not PA5 , I really don't know why.

does this output mean that i have a problem with my board ? because PA5 and PA2 are not connected in any way from the schematics.
