STM32W108 temperature sensor problem

Hi guys,

I've got a problem when trying to read the temperature from STLM20 on-board sensor. I'm using the STLM20_ReadTemp() function and when it reaches the line

while (!( ADC->ISR & ADC_IT_DMABF));

it never goes out of that loop. In call the STLM20_Init(() function in the beginning, I think that ADC->ISR doesn't change it's value when it should (should there be an interrupt?)

I'm using MB950 board with STM32W108CB

Thanks for your help.

Hi przemek,

Could you please follow the temperature sensor example in ''STM32W108 standard library firmware'' V1.0.1''. You will find that STLM20_ReadTemp() is used after some configurations in main.c

Let me know if you need more details.

With regards,
