i use the STM32F303. How can i active the synchronous clock mode without DUAL MODE? In dual mode it is possible by writing ADC_CCR_CKMODE_AHB_DIV1, ADC_CCR_CKMODE_AHB_DIV2 or ADC_CCR_CKMODE_AHB_DIV4 to CCR of the ADCConversionGroup.
The CCR is not available in the driver without dual mode in the adc_lld_start_conversion function:
Code: Select all
void adc_lld_start_conversion(ADCDriver *adcp) {
uint32_t dmamode, cfgr;
const ADCConversionGroup *grpp = adcp->grpp;
#if STM32_ADC_DUAL_MODE
uint32_t ccr = grpp->ccr & ~(ADC_CCR_CKMODE_MASK | ADC_CCR_MDMA_MASK);
#endif
and in the ADCConversionGroup:
Code: Select all
#if STM32_ADC_DUAL_MODE || defined(__DOXYGEN__)
/**
* @brief ADC CCR register initialization data.
* @note The bits CKMODE, MDMA, DMACFG are enforced internally to the
* driver, keep them to zero.
* @note This field is only present in dual mode.
*/
uint32_t ccr;
#endif
I think this has to be available.
Thank you.
