Hi,
The code hangs on:

Hello,

Compiling for STM32G0 with KEIL 5.33, chcoreasm.s gives 3 errors:

os\common\ports\ARMv6-M\compilers\RVCT\chcoreasm.s

- .zombies b .zombies
+ _zombies b _zombies
- _port_exit_from_isr
+ __port_exit_from_isr
- .waithere b .waithere
+ _waithere b _waithere

Hi,

I did this test, something is writing in the structure.

uint32_t CFGR1x, CFGR1y, CFGR1z;

/* ADC configuration and start.*/
CFGR1x = ADC_CFGR1_RES_10BIT | ADC_CFGR1_EXTEN_RISING | ADC_CFGR1_EXTSEL_SRC(5) | ADC_CFGR1_DMAEN | ADC_CFGR1_DMACFG ;
adcp->adc->CFGR1 = CFGR1x; // cfgr1;
CFGR1y ...

Hi,

The cfgr1 variable has an incorrect value.
I defined a variable:
uint32_t CFGR1x;

/* ADC configuration and start.*/
adcp->adc->CFGR1 = cfgr1;
CFGR1x = cfgr1;

Then the value of CFGR1x is 0x00000543 (it should be 0x0000054B)

Sori,
.cfgr1 = ADC_CFGR1_RES_10BIT |

CFGR1 0x00000543

const ADCConversionGroup adcgrpcfg1 =
{
.circular = true,
.num_channels = ADC_GRP1_NUM_CHANNELS,
.end_cb = adcCallback, // NULL,
.error_cb = adcErrorCallback,
.cfgr1 = ADC_CFGR1_RES_12BIT |
ADC_CFGR1_EXTEN_RISING |
ADC_CFGR1_EXTSEL_SRC(5),
.cfgr2 = 0xCD,
....
}

adcStartConversion(&ADCD1 ...

yes, the setting does not reach the ADC, regardless of the setting, bits 3 and 4 of CFGR1 remain at 0.

Hello,
I am doing tests with the ADC of the STM32G071 and it is not possible to change the
resolution is always 12 bits.

.cfgr1 = ADC_CFGR1_RES_10BIT |
ADC_CFGR1_EXTEN_RISING |
ADC_CFGR1_EXTSEL_SRC(5),

Hi,
I didn't find any example, they are all for RT.

Daniel

no problems with STM32F051
