ChibiOS Free Embedded RTOS

thanks

Maybe best solution will be perform a ADCv1L0XX ?

os/common/ports/ARMCMx/chcore_v6m.h

have check for GCC version

/* Handling a GCC problem impacting ARMv6-M.*/
#if defined(__GNUC__) && !defined(PORT_IGNORE_GCC_VERSION_CHECK)
#if __GNUC__ > 5
#warning "This compiler has a know problem with Cortex-M0, see bugs: 88167, 88656."
#warning "*** Use ...

Can you post here when you make a final decision what solution apply

What the best solutions for this situation? use this fix or try to define a ADC ISR ?

Try putting it to FALSE in registry, it disables the ISR.

Helped!!!

Now i can catch adcerrorcallback

Thanks, i'll try.

It is a known error, the ADC ISR is not defined for the L0, moving in bug reports.

You may re-enable the ISR and it should work.

you mean

// re-set IER

adcp->adc->ISR = adcp->adc->ISR;
adcp->adc->IER = ADC_IER_OVRIE | ADC_IER_AWDIE;


and re-enable
adcp->adc->CR = ADC_CR_ADEN;
while ...

Seems bug
