(++) Configure SDADCx clock divider with HAL_RCCEx_PeriphCLKConfig.
|
|
(++) Enable power on SDADC with HAL_PWREx_EnableSDADC().

(++) If interrupt mode is used, enable and configure SDADC global
|
|
interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().

|
|
with SDADC handle using __HAL_LINKDMA.
|
|
(#) Configure the SDADC low power mode, fast conversion mode, slow clock
|
|
mode and SDADC1 reference voltage using the HAL_ADC_Init() function.
|
|
Note: Common reference voltage. is common to all SDADC instances.
